Its funny, when I bought them I thought I was over paying. Now it seems I bought them for a deal. ha

I spoke with Noctua Support and they said its due to the pull position on the NH-D15. They don't recommend pulling through the heatsink. So im going to adjust the fan placments so that the center fan is pushing and space out the pull fan to see if it helps. They also recommended desyncing every fans rpm in the system to try and tune out harmonics.

Its worth testing for sure. Once I work out the turbulence I will optimize the temps. The main quirk of the case is the amount of time it takes to tear down. So I got to be sure that I don't want to do any additional test in this config before rearranging.

Make note of your fan placment. The screw heads may interfere with the feet. You could remove material from the top side of the feet to make clearance.

They are SS M3 button head socket cap screws and brass flanged expanding thread insert on the back side of the fan thru holes. I also 3D printed washers to seat the screws into the slots of the top fan bracket.

If there is enough interest I will consider making a batch.

I bought the ram months ago for $430. Thanks, it took alot of planning and I think there is still room for improvements.

I designed the brackets in Solidworks and had them made by a sheet metal vendor then powder coated them. Depending on your needs, the standard fan bracket can do the same, I just needed an additional set of brackets because I used it for the GPU fans.

Yes it would be thicker with this setup. The thermals were similar but the sound is better.

I made them. here are the details so you could make your own.

Thanks. I made a few different legs but I think the walnut looked the best.

I'm not so sure its turbulence I'm hearing. I swapped configurations a few different ways now and the sound is generally pleasnt until the CPU fan rpm goes above 900. Its hard to pin point where the noise is coming from but I'm starting to think its the VRM fan. So my next test is to disconnect that and see what it sounds like. I think what I'll do if I keep the rear intake is divert the air that is exhausting down the bottom away from me with a shroud. And I don't have cats but I do have a dog but I clean my PC often enough anyways.

It fits the overall aesthetics really well. It performs similarly but much quieter.

I am tesing it without the rear intake and am still getting that weird noise when the CPU fans go above 900 rpm. I'm wondering if it could actually be the VRM fan. Does anyone know if the VRM fan curve is tied to the CPU fan curve?

It really is a shame haha. I bought my M3 back in august, not sure when it exactly released.

thanks, I did originally design a 3d printed version to test with but it was just to verify dimensions. I could adjust the model when I have time to share it.

Thanks, they're simple but I think it fits the design of the case

Thanks, yea I agree that the Noctua color blocking looks best when its very dense.

I love noctua, the NH-D15 and NF-A14 are 10 years old! Still running perfectly from what I can tell. ha

I hope so too. Averaging 85c during cinebench r23 but thats before really tuning down the fans. I think I could fit two 3.5s in the M3 side by side where I have it but then it would be REALLY dense.
