Stealing Noctua's quiet airflow mod

Okay I've had this turbulence issue way more times than I can count so I thought I'd share the fix for it in this quick video! btw some crazy monitors coming out in the next few weeks so stay tuned.

Hey bro could you do a video about keyboard often called "cheaper wooting" ? heres a name DrunkDeer G65. I want to buy it but idk if its worth it

If u could add holes to the spacer could bring more air

make another setup review and hurry up boy

bro this is gonna be a weird question, but where do you get your tee’s?

can u do a review on the AOC 24G2ZE it has a 240hz ips panel for 164$

Time to learn some CFD 😁

Use different material may give good result?

Can you send out a free pc for me. ¿

I printed these and realized the screws I had were too short and can’t seem to find any longer than 12.5 mm but I think you need around a 15 mm screw. What screws did you use?

Since you are so good at testing and showing the results on a graph can you do a test to see how many girls like you if you use windows vs Linux?

I've always wondered why these disappeared. They existed in the mid 2000's and then just went away. I didn't know Noctua had brought them back.

everyone has headphones on no one heairs their fucking pc LMFAO

I know I'll sound Slavic now, but what about slapping a 5 mm spacer under each fan? No 3D printer over here. 🤔

time to sell this hard work back to noctua or sell the work to someone who can mass produce these lol

Not entirely sure but I believe even putting spacers/washers on the head of the screws that attach the fans might also help further dampen the vibrations. Maybe just put spacers everywhere possible.

4k pc gaming minimum power supply wots net is roaming stability to play

I use double sided foam tape to space out a fan and it works really well with little cost involved. I think the vibration isolation from the case also brings down the noise level a lot.

Inspired me to get a few to try out on my PC. For some reason my comment got deleted (maybe advertisement?) In any case they're a few bucks and TPU each. Can be bought from a big chinese marketplace :PP

hopefully will improve on the quality and pitch of my PC. Thanks for the heads up, what a great vid!

quality of the content is unbelievable. I have been thinking about the same issue for so long!! Thanks man.

Can u please test the polar 65 (wooting clone)

This channel continues to be awesome for actual geeks. No clickbait, just pure technology and modding. <3

Does anyone have recommendations for the best material to 3D print this with? I’m not too literate with 3D printing. I assume Nylon would be good to help dampen noise?

So you're saying you're a stealer?

I like this evolution of your channel

what software do you use to create these things?

This exact issue is why my pc is entirely exhaust fans pulling air through lol I'm way too picky about the noise from my PC
Also have you tried putting a big CPU heatsink on the GPU? I did that and it's awesome

I’m still waiting for someone to make an asymmetrical fan like Apple did for their MacBooks years ago so that there isn’t a single, high resonant tone, but the noise is spread across a few frequencies so that all frequencies are lower.

whole lotta turbulence

Go figure, Noctua knowing (and publishing) just the right mm that provides improvements. Great video, and just reaffirms that Noctua is just so damn good at what they do!

What is the name/model of the 3d printer?

so basically just add a spacer or open your side case a bit.

Did you see differences in the material type? Like TPU, PLA or ABS?

My AIO is very loud.

Do you just recommend this on intake fans or also on exhaust fans?

soooooo a set of phantex halo's would do the job AND GIVE YOU RGB!@?!

i dont have a 3d printer can i buy some of these off you? @optimumtech

this is something that i have done but for my main pc i dont need it as the speed of the fans never go above 1000rpm for me while i am gaming, max temps for cpu/gpu is 58/55

I've been using slim 120mm fans with old phobya branded 3mm rubber gaskets in the bottom of my ncase for years to solve this issue.. I was actually frustrated when I went to buy more last year and found they'd disappeared off the shelves years ago.

@optimumtech can you post STL/STEP files on Printables?

Thanks for sharing this 🙌

Reverse flow fan would fix that issue.

makes me wonder if there's a real fan blade design that could keep the noise level below 40 at like 1700 rpm

Wonderful video, these look like something people could fabricate themselves even without a 3d printer.
However, it would be interesting to see how different the sound is from other materials like TPU or carbon fiber and nylon.
Additionally, one other modifier i would like to see tested is hole diameter. I imagine most of the turbulence is coming off of the fan blades outer edge/tip.
Would bring in the diameter help to dampen or direct the air in a different way, especially on a TPU printed one.

This is already a long comment, but the pitch of the hole might also make a difference, ie a sloped edge going towards or away of the fan center.
Great video as always!

I've wondered this for a while. Thanks for testing this!

I had this issue on my phanteks case.. so I cut out the mesh with a dremel haha

"thicc"
they gooners at noctua lol

May I know which accoustic standing panel do you have please ?
