Breaking the Rules: We 3D Printed a Noctua Computer Fan

0:00 We're finally gonna answer the question.

0:02 Only with this level of precision can you get the true answer

0:06 to the question of if I buy an Noctua NFA 12G2 for like $40,

0:13 destroy it to claim the motor and then print my own to put the the motor

0:21 into like some sort of cannibal movie where they wear the skin of their victims.

0:27 Will it be better than the original Noctto fan?

0:29 Well, we will have your answer.

0:35 No one else is going to do this to this degree.

0:42 It's working.

0:43 Hang on.

0:47 We've made our own unofficial official Noctua fans.

0:52 Noctua released 3D CAD models of several of its products,

0:55 recently adding to them the NFA12 G2.

0:58 Noctua's page says that these are for mechanical design,

1:01 spacing, animations, but not 3D printing.

1:05 These files are definitely not supposed to be 3D printed.

1:09 Noa says, quote, "Do not use these models for 3D printing." End quote.

1:13 Now, this immediately was met with headlines like, quote,

1:15 "You can now 3D print your own Noctua fans, but you can't build a full clone.

1:20 Challenge accepted.

1:22 Allow us to introduce you to the full clone.

1:26 I to be fair, we did have to buy a Noctua fan and cut it

1:32 into pieces to make the full clone cuz we needed to get the motor out of it.

1:36 But technically, they said we couldn't build a full clone and it's right here.

1:40 Look, I guess what we're saying is all you

1:42 need to build your own Noctua fan for cheaper

1:46 is to to first buy a Noctua fan and cut it into pieces and take the motor out.

1:51 But and then then you can make your own fan.

1:53 Today, Mike's going to work through making the fan and 3D printing it.

1:57 I'm going to run Noctua's NF12G2 through our fan tester,

2:00 and then I'll test Mike's version of it.

2:02 If it works at all, we'll be happy with it.

2:06 But the full disclaimer is we're like brand new to 3D printing.

2:10 little late to it.

2:10 I mean, I've covered it in the past, but this is our first kind of real project.

2:14 We've done anything with a 3D printer in a video.

2:16 So, a lot of you know a whole hell of a lot more about 3D printing than us.

2:20 So, we are going to be noobs at going through this process.

2:23 And, uh, if you have ideas or feedback or whatever, wide open to it.

2:27 We'd love to read it, to study it.

2:29 Uh, we've had a lot of fun with 3D printing.

2:31 And Mike in particular with Andrew, they've been working on the 3D printer

2:35 for a while with a bunch of different projects.

2:36 So, this is kind of our first one we're showing off.

2:38 Uh, and we're just we're just we're going to make

2:41 some fans and then we're going to go completely overkill

2:44 on testing those fans in a Hemi and a quick

2:46 chamber and on a fan tester because why the not?

2:49 It's fun to do.

2:50 Let's get into it.

2:51 Before that, this video is brought to you

2:53 by the Thermaltch TR100 portable miniITX case.

2:56 The TR100 case has a mesh ventilated front panel,

2:59 heavily perforated side and top panels,

3:01 and claims to support up to 280 mm liquid coolers,

3:04 and large GPUs up to 360 mm long and 70 mm thick.

3:08 It even has an optional suitcase with cutouts for the system,

3:11 a mouse, keyboard, and monitor for transport.

3:13 The Thermaltch TR100 MiniITX case targets portable,

3:17 smaller form factor PC building while

3:19 maintaining compatibility for relatively large components.

3:22 Learn more at the link in the description below.

3:24 All right, so Noctto files aren't exact

3:26 one:1 replicas of the actual fans they sell.

3:29 They're close in some ways, but they're very different in others.

3:32 And uh it's still awesome that Noctar released CAD files

3:36 at all because it allows us to do stupid stuff like this.

3:39 Okay, that's all right.

3:42 That's that's maybe not the best example of the we we'll we'll fix that.

3:46 Anyway, it's awesome they released these because it's fun

3:48 to do this stuff and they are clear about the uses.

3:51 They say quote, "These public 3D CAD models accurately represent mounting

3:55 dimensions as well as the overall external dimensions of the product.

3:59 to protect our intellectual property.

4:01 Certain features such as fan impeller geometries have been slightly

4:05 modified while remaining visually very close to the actual product.

4:08 End quote.

4:08 Let's jump over to Mike to build the fan.

4:11 Okay, my job is to print that.

4:15 So, this is the G2 fan.

4:18 Um, when they initially announced that they

4:21 were going to release these CAD files publicly,

4:23 um, I went ahead and downloaded the, uh, A12 25 120 mm regular firstg fan.

4:31 Uh, and I went ahead and just printed it.

4:33 Uh, there's a lot of things that aren't exactly 3D printing optimized.

4:36 Obviously, the software, we're using Bamboo Lab software,

4:40 um, threw in a bunch of supports, rightfully so.

4:42 There's a bunch of overhanging areas.

4:44 Um you can see a bunch of supports

4:46 on the sides here for uh where all these cutouts are.

4:50 And then the first challenge we're going to deal with or first

4:54 problem we're going to solve for is going to be the impeller.

4:57 So you could see that the uh file has absolutely no

5:01 cutouts or space or modeling for where the motor would go.

5:05 And we can see that here in the software as well on the G2 fan.

5:10 You can see that's just a solid block.

5:13 Um, so we're going to have to fix that and make it fit on a motor.

5:18 Um, speaking of motor,

5:20 we're going to need one first because obviously we can't 3D print a motor.

5:23 So, let's go cut up an actual knock to a fan and harvest its motor.

5:27 They've got like a sticker of some kind on the back here.

5:33 Okay, cool.

5:34 W That's like a hefty like metal.

5:37 That's like a serious serious sticker.

5:40 It looks like this is just press fit.

5:56 We're free.

5:57 Looks pretty good.

5:59 So, truth be told, this is actually the second time I've done this.

6:02 Um, so I'm going to cut along like right in front of the top

6:08 of the impeller blades here along the entire outside of this motor housing.

6:12 So we did this earlier and I realized that the um impeller material

6:17 is actually structural so it helped it float in the center of the motor.

6:23 But like now this doesn't spin freely.

6:27 So, I've got to We have to make sure to keep part of this impeller intact,

6:32 otherwise we can't use the motor.

6:43 Take a look.

6:43 See if this thing It's going.

6:51 Look at that.

6:54 Better than the day it was made.

6:57 All right, so Mike is 3D printing his fan.

6:59 We're going to test the Noctua NFA12 G2.

7:04 We need baseline numbers of the PPV model.

7:07 And to do that, we're going to throw it on the fan tester,

7:11 which we've been using this a lot lately in our case reviews.

7:15 That's going to provide air for the machine.

7:17 Now, we need the power from the circuit breaker.

7:23 This is our pre-flight checklist.

7:25 We need to um make sure it's all working and calibrated.

7:28 So, I switch to manual mode.

7:30 If you peer in through the window here,

7:32 you'll see that there's these almost submarine like vault doors that open

7:37 and close along with the counter blower in the machine, which is down here.

7:41 That's what provides the testing capabilities.

7:44 We need to also calibrate our results for the machine.

7:50 First though, we need to zero this out.

7:56 Yeah.

7:59 So, that's just opened up all the valves,

8:02 the doors in here that we were just looking at.

8:04 They're all open now.

8:05 And down here, you can see we've got like a negative 002.

8:09 That's fine.

8:10 That's within reason.

8:11 But zeroing it out.

8:12 Uh sometimes you'll get like a minus1 minus 2.

8:14 This is pressure millimeters aqua.

8:17 And um what the machine's doing now is calibrating,

8:20 getting everything set back to zero.

8:22 So then when we can run our test,

8:23 it starts at baseline zero instead of like minus two or something.

8:26 I got to go back behind the machine really quick.

8:28 All right.

8:28 So on the back here we have Oh.

8:30 Oh.

8:31 Oh, there's there's snipers.

8:33 It's got to be Jensen's people.

8:36 They found us.

8:37 They've infiltrated us.

8:38 They've infiltrated.

8:39 This is pretty empty right now.

8:40 I need to fill this for It's still wet, so that's good.

8:44 So this is a sock.

8:45 I It's not like literally a sock.

8:47 That's just what they call it.

8:47 This is a piece of cloth.

8:48 It hangs over this.

8:50 This thing's an uh thermometer and so there's this like metal rod that sticks

8:55 in and actually if you get a shot down so you see TD is temperature dry.

9:02 TWW is temperature wet and this D is a uh so this is a temperature sensor.

9:06 The one in this box is the same thing.

9:09 It's just a thermometer except it's got that piece of cloth wrapped over

9:12 it and then there's this fan uh that just provides some some cooling.

9:16 And so what this does is this going to let us adjust for humidity.

9:20 So, humidity control uh and altitude and things like that really matter.

9:23 So, in order to do our test in, I need to get this at least half filled.

9:28 We have now zeroed out.

9:30 So, auto zero is at zero.

9:32 If you look down here, every gauge that should be zero is zero.

9:35 Now, we just need to actually run a test.

9:39 And the first thing we're going to do is a quick orifice tester for calibration,

9:46 which is the uh system resistance curve.

9:52 And we're going to do resistance settings starting

9:55 at four steps of four going up to 40 CFM.

9:58 So, the way this works is that counter blower I was showing

10:01 earlier is actually gonna provide all of the the movement of the air

10:05 for the machine and it's going to try and suck air through

10:09 into the machine uh through this kind of like known size uh hole.

10:14 So, you can see here we've got

10:18 calibration reports in the back from the manufacturer.

10:22 And so every time we do major major rounds of testing, I do this.

10:27 I do this for the uh uh Haven BF360 most recently.

10:32 And here's our calibration report.

10:38 I'll check it against this.

10:40 So this um at this point this is

10:43 this is running and we'll check in when it's done

10:47 and then start the test of the noto fan

10:51 while Mike is hopefully things are going smoothly in there.

10:54 I don't know.

10:55 All right.

10:55 So after removing the motor I went ahead and measured

10:57 the dimensions the outside dimensions of the motor housing here.

11:01 Um and I've modeled or cut us a hole inside

11:05 of the impeller that hopefully will fit snugly when we print it.

11:09 Um, so I think our next step is to go ahead

11:11 and send this to the printer and see what comes out.

11:18 I've got the first test run of the impeller done here.

11:22 And just as a quick side note, we're using Bamboo Labs PLA Basic.

11:26 Um, I did a little bit of research.

11:28 I know there's stiffer filaments out there,

11:30 but this was the stiffest one we had on hand and we've got a lot of it.

11:34 So, I wanted to just use something simple and easy to work with.

11:37 I mean, this this stuff prints really well.

11:39 So, um, but speaking of printing well, this did not.

11:42 Um, so the Bamboo Lab software threw a bunch of supports on the underside.

11:47 So, it printed like this, of course,

11:49 and it threw in a bunch of supports on the underside and still was

11:52 not good enough to help um prevent

11:55 this from becoming all stringy and and uneven.

11:57 Obviously, this is going to perform like crap if

12:00 we try to, you know, move air with it.

12:02 Um, so I think we're going to have to solve for that next

12:05 and try to figure out either supports or some other kind of solution.

12:09 But, uh, why don't we go ahead and try to test

12:11 fit this on the motor to see if it fits at all.

12:17 Okay.

12:17 So, it's a little tight.

12:20 So, I'll have to fix that.

12:21 So, I'm going to go address that and uh

12:24 we'll check back in after our next test print.

12:32 Okay, so this this print kind of failed,

12:34 but I think it has enough for us to do like another dimensional test.

12:37 What's different about this print is the layer height.

12:39 We went down to a much lower layer height.

12:41 So, previously we had been printing at 02, which is kind of your default.

12:45 Um, this is at 08.

12:47 Um, what I noticed, and you know,

12:49 as a disclaimer, we're very new to 3D printing.

12:52 We're figuring this out as we go.

12:53 Um, so if you guys knew that, more power to you.

12:57 where where we did not this was discovered during this project.

13:00 So, um but we noticed what we noticed

13:02 was when we swapped to the lower layer height,

13:04 it had a lot less uh it had I was able

13:07 to do a lot more aggressive of an angle before it added support.

13:10 I think going forward I'm just going to print in a super low

13:13 layer height cuz the print time doesn't really matter for this type of project.

13:16 We're just printing it one off.

13:17 So, um let's see.

13:21 Oo, I think we're in business.

13:25 It's starting to look like a fan.

13:26 This is spinning pretty easily.

13:28 This might be a little too loose.

13:29 So, let's go ahead and tighten that up.

13:31 To test this, I don't need to print the whole thing.

13:33 So, I've just been printing the collar here.

13:35 Um, and I found a dimension that fits pretty darn good.

13:41 And that's like nice and snug.

13:43 So, let's go ahead and print the whole impeller.

14:06 Hopefully this fits nice.

14:11 A little loose, but I think that'll work.

14:14 Yeah, I think that'll be just fine.

14:19 Nice.

14:19 Cool.

14:20 Next step is to work on the frame.

14:22 And the first step of that is going

14:24 to be figuring out how we're going to mount it.

14:26 And then we'll we'll get to measuring it and making it fit to the frame.

14:31 All right, so we're back.

14:32 This is done.

14:34 The uh the system resistance report is complete.

14:37 All the numbers look good.

14:38 These match our calibrated report.

14:40 And so what this means at this point, machine's good.

14:42 We're calibrated.

14:43 We've got the water refill.

14:45 Everything's looking good on it.

14:47 And now I need to actually get the noto fan on here.

14:50 We're gonna need to do a two-step process.

14:52 One is getting all the screws in.

15:00 Cool.

15:00 Okay, couple more steps here.

15:02 First one, we need a way to read this with a laser.

15:06 Someone's left safety goggles at my station here.

15:09 I'm I'm not sure if we just forgot to put them back

15:12 or if it's it's a it's a message for me from OSHA.

15:16 So, uh, this part's pretty dangerous.

15:18 We're going to apply the scissors to uh, attack sensor.

15:31 Thank you, Steve.

15:32 Safety first.

15:33 Are you ready?

15:34 I think so.

15:35 You might want to adjust your volume down.

15:43 Okay.

15:46 Cool.

15:48 I need to adjust this laser tack.

15:52 You'll notice there's this green LED here on the back of the laser tachometer.

15:56 And when I spin this, when the sticker crosses the laser, we see it light up.

16:03 PC control mode, optic mode.

16:06 And now we're going to set up a test.

16:07 So, we're going to do a fan performance curve test.

16:09 And then I'm going to run one set of tests at just 100 for everything.

16:14 100% duty cycle, 100% start and stop.

16:16 We'll do another set of tests at 40% start with 5% increments, 100% stop.

16:22 So that means 40, 45, 50, 55, so on.

16:24 But we'll start with 100 100.

16:26 All right, good to go.

16:29 You can see it's starting to provide power for the fan.

16:32 So this is just kind of Yep, there we go.

16:34 12 volts.

16:34 So everything is starting to spin up.

16:37 And in a second if it starts opening valves.

16:40 Yep, that was the first valve.

16:42 So, very smooth.

16:44 We'll let this finish.

16:44 We'll get the results and then once they give me the other fan,

16:47 I'll throw that on here.

16:53 That looks pretty good.

16:54 Let's get it measured and start fitting the frame to it.

16:56 Okay, so I've been hard at work on getting the frame ready.

17:05 After a number of different attempts,

17:07 I decided to try to make the frame

17:09 itself a little bit more 3D printing friendly.

17:11 If we take a look here at this model on the right,

17:15 um this is going to be our more final 3D printed version.

17:19 So, you can see I've I've removed all the cavitation um

17:22 that that they they put in there to reduce weight and, you know,

17:26 material for injection molding, but obviously that's not a problem here.

17:30 And we want that all kind of filled in.

17:31 I removed the holes for the rubber grommets that go on the corners of the fan.

17:37 Um, I wanted to make uh very sure not

17:40 to remove any features like these uh outlets and inlet kind

17:46 of uh the fillets that would affect potentially affect

17:50 the performance cuz I don't want to affect the air flow.

17:52 I want to retain as much of whatever

17:54 they have modeled here for air flow as possible.

17:57 Um, I've also been working pretty hard on the dimension.

18:02 So, dimension of this hole.

18:04 So, this is where this this brass or I assume this is brass,

18:08 but where this part of the motor is going to insert into the frame.

18:11 I I really didn't want to glue this or use anything

18:13 kind of permanent in case it wasn't good or something broke.

18:16 Um, so I added a very slight um and it's not perceptible to the eye,

18:21 but a very slight taper to this hole so that when we insert it,

18:26 it's going to go in partially,

18:29 but then eventually stop when it hits that taper and it gets too tight.

18:33 So, let's go ahead and slap it all together and see what happens.

18:43 Press that in.

18:46 Look at that.

18:49 I made a fan.

18:50 Well, I didn't make it, but I printed it.

18:54 I made it printable.

18:57 Don't worry about that.

18:58 Those are those are normal noises when you're making fans.

19:05 It's working.

19:06 Hang on.

19:11 All right, that sounds better.

19:14 What was the issue?

19:15 It was just striking a little bit uh because

19:17 I didn't have it far enough on the hub there.

19:19 But now it's working.

19:21 We got some special filaments for maybe a final run.

19:26 Some color appropriate.

19:28 I don't know how this one's going to print.

19:30 This is like a wood fil filament,

19:32 but it looks pretty close to the the brown that we want.

19:40 And this looks pretty close to the beige that we want.

19:52 Is it done?

19:54 Oh, it's ready.

19:56 It's knocked to our covers.

19:58 Wow.

19:59 Okay.

19:59 Oh, don't forget we don't want it to vibrate.

20:05 Oh, yeah.

20:05 Oh, yeah.

20:06 This is definitely acoustically um Well, it's Hang on.

20:11 Okay, now the acoustics should be pretty compelling.

20:16 I just picked up a beige PLA and then

20:18 we actually had some rosewood wood PLA grain.

20:23 Yeah, wood grain, which is it they say that and I was like, "Oh, okay.

20:27 It's just going to look like wood or have wood,

20:29 but it actually smells like wood when it's printing.

20:30 So, I don't know if they actually like put wood.

20:33 There's wood.

20:33 There's wood in it.

20:34 It's uh I think it was like 30% or something was the marketing,

20:37 which is wild that it doesn't cause more problems, but yeah.

20:41 All right.

20:41 I'm curious about this.

20:43 So, Oh.

20:44 Oh my god.

20:45 There's We're going to need a taxi to get from the blade to the frame.

20:51 Three 3.7.

20:53 They haven't tried marketing bigger number better yet for that one.

20:56 So, I mean, context for everyone,

20:58 the getting the blade closer to the frame is better for performance.

21:01 You're utilizing more of the inner area to actually push the air,

21:05 and there's um it'll be better for flow.

21:08 But the downside is different plastics will stretch as it spins and with age,

21:14 and so they start clipping the inside of the frame housing.

21:17 Um, but this uses liquid crystal polymer, uh,

21:20 which to my knowledge is not 3D printable,

21:23 but is also the reason these fans are unbelievably expensive.

21:27 But anyway, I think they're definitely sub 1 mm.

21:30 Do you have any Do we have any feeler gauges?

21:33 Yeah, feeler gauges should be like 0.5 probably.

21:38 Oh, wow.

21:38 It's also going to be hard cuz it's on a I'm

21:40 putting a flat feeler on a curved surface, so sub 6, right?

21:47 Yeah.

21:47 So, subsight.

21:49 Yeah.

21:49 Maybe maybe.5 something.

21:51 This is one of the real ones.

21:53 Sorry, I didn't mean to.

21:55 They're both real.

21:56 Okay.

21:57 This is one of the Noctua fans.

21:59 Uh, and then this is the 3D printed one.

22:02 We've got two 3D printed ones.

22:03 So, it's press fit.

22:04 That one actually the Noctua the second round came

22:07 out a little bit tighter than the first round.

22:09 So, it might be due to like filament or just because it was the same setting.

22:13 So, yeah.

22:13 I mean, that's worth mentioning, too.

22:14 The filament's going to impact a lot of stuff.

22:16 We didn't try to like actually do a bunch of um

22:20 research on if you were to 3D print the fan, which filament would be best.

22:23 Yeah, I will.

22:24 I will put it on the fan machine.

22:27 Okay, best of luck.

22:28 Good luck, little fan.

22:29 Yeah, Noctua has not provided the same exact files

22:34 for a lot of reasons we already talked about.

22:36 And so, uh I I do not expect their fan with a 3mm gap will perform

22:41 anywhere near as well as the fan with like a 0 point whatever it was, like five.

22:45 I don't know.

22:46 It's like plus or when you're at plus or minus 0.1 from 0.5,

22:50 it doesn't really matter the 0.1 anymore against like 3.17.

22:54 So, uh, we just need Maxim for this test and it's fine.

23:00 I've already tested a a gray version of the 3D printed fan from Mike.

23:05 So, now the question is,

23:08 how much do the Noxy colors really add to the performance?

23:12 The gap fill this time is going to be substantial.

23:18 All right, let's see if it works.

23:20 Set up a new test.

23:22 Mike felt pretty good about it, so I trust his judgment.

23:26 There's no bad noise to it.

23:28 I don't know.

23:28 It's pretty impressive, honestly.

23:30 It's the It's the That's the the new Gamers Nexus fan.

23:38 Look at that.

23:38 You can't even tell them apart.

23:40 So, with that, let's cut over to the chart and wrap this up.

23:45 All right, the results for this are pretty simple, but they are fun.

23:48 The 3D printed NF12G2 file from Noctua in combination with an actual NF12 G2

23:53 motor resulted in far worse results than an actual NFA12 G2 that was made,

23:59 you know, in a factory with balancing

24:02 and more precise CAD file and liquid crystal polymer.

24:06 Credit to Mike.

24:07 He did an incredible job getting this thing to work at all.

24:10 And it's actually a lot better than I would have expected.

24:13 It's just not anywhere close to the actual NF12 G2.

24:17 But yeah, it's probably on par with like

24:18 a $1 case fan from a factory or something.

24:21 The NFA12 G2 had a maximum pressure result of 3.23 mm H2O.

24:26 In like forlike conditions, the 3D printed version of the fan had a 2.65 result.

24:31 The flow was also far apart with the NF12 G2 at 65 CFM and our fan at 36.9.

24:38 Amazingly though, we had acoustics at the same

24:40 level when tested in our Hemiooic chamber.

24:43 We tested at a distance of just half a meter and at a 100% fan speed

24:47 because we wanted to make sure we maximized

24:49 the ability to see differences in the results.

24:51 By noise level alone, there weren't really any differences.

24:54 The 3D printed fan was technically 1 dB louder.

24:57 Some of that lack of higher noise may

25:00 just be because it's not moving as much air.

25:02 As for the question we all really cared about,

25:04 printing with a different color filament and apparently about

25:07 30% wood grain and the dark brown for the blades.

25:10 I don't I don't know if Nocta has considered using wood for their blades,

25:14 but we've proven that at least in some capacity you can.

25:18 I guess they do it in propellers, but anyway, it didn't result in major changes.

25:22 Although we thought we had discovered

25:23 Noctua's secret to performance, this objective, definitive, well-refined,

25:28 and researched testing process proves that once and for all,

25:32 brown and beige colors are not the reason

25:34 that Noctua's fans perform the way they do.

25:36 We thought that all this talk of so-called physics was just

25:40 pure and that it was all to do with the fan colors.

25:43 Maybe we got the hex code wrong or we need a different panone.

25:47 But at least for now,

25:48 it looks like Noctua has won this battle with its the so-called physics.

25:53 For fun and just because we have it here,

25:55 we also pointed our Hemiian coic chamber and its mic and mic

25:59 at the 3D printed fan and the Noctua NF12G2 to test for frequency spectrum.

26:04 They both have spikes that are similar,

26:06 but the 3D printed fan spike occurs at 369 hertz.

26:10 The NFA12G2 occurs at 275 hertz,

26:13 which almost perfectly lines up with the blade pass frequency.

26:16 We're not sure exactly what the spike is from the 3D printed version,

26:19 but it at least occurs in a similar way, just higher up in the frequency range.

26:24 The Nocta fan has a much lower noise level

26:26 overall across the high end of the frequency spectrum.

26:29 It's technically louder in the 1200 to 2,000Hz range, but lower after that.

26:34 And then the total noise level is pretty similar.

26:36 The 3D printed fan is also louder in the lower frequency range.

26:39 significantly actually in the 200 to 500 Hz range in particular.

26:43 Overall, the level is about the same, but the 3D printed model has less smooth

26:48 of an overall noise arc from low to high frequency.

26:51 So, that's going to be it for this content.

26:52 Now, again, Noctua says they don't even want you 3D printing these fans.

26:59 It's not like a It's not a binding contract,

27:01 but it's supposed to be for people to use for their PC

27:04 building projects and modeling and things like that and software.

27:08 Uh, but it was fun.

27:09 You can 3D print it.

27:10 You're not going to get a motor.

27:11 Uh but as we've shown here, you know, Noctua,

27:13 I think probably can get over the fact that we went against them

27:18 and 3D printed the fan because we did have to buy four Noctua fans,

27:23 which is like uh I think it was I think it was like $200.

27:29 Uh it was Yeah, it was about $200.

27:32 150 bucks with taxes.

27:34 We had to buy four Nocta fans to cut

27:36 into pieces and reclaim motors for this testing.

27:39 So, I don't even think they could be that mad about it.

27:42 Uh, but I I Oh The all the testing is going to be invalid.

27:47 Wait, wait, there's still time.

27:56 Okay.

27:57 Oh, that was close.

27:58 All right.

28:00 So, the first number the first number might be wrong,

28:02 but the rest of them will be good.

28:03 Uh, so that's going to be it for our testing.

28:05 Um, it is it's about half as good as the Noctua fan for the flow.

28:13 And we're not going to talk about the pressure, but you could feasibly do it.

28:18 And I guess if you wanted to like buy a 50 cent

28:24 like Hua Bay special fan and rip that motor out and then

28:30 3D print this and you know and hollow it out with a Dremel

28:34 and then taper it so you can press fit it and everything.

28:37 If you did that, you would have a fan

28:40 that looks like an Octa fan for very cheap.

28:44 So maybe that's the consumer that's the consumer advice we have for you.

28:48 Thanks for watching.

28:49 To support this type of content,

28:51 which clearly deserves the support uh that we have

28:56 spent like a week on this because it was fun, you can go to store.garosexus.net,

29:01 grab something like one of our modmats,

29:02 our coaster packs, uh soldering and project mats,

29:05 all useful for this kind of thing,

29:07 especially the soldering and project mats have been really successful lately.

29:10 So, thank you for that.
