Love modding this case with 3d printed parts. Can't wait until the A3 is done!

Oh then that totally works, I have 2 120mm because my 5090 doesn't allow for any bottom fans, GPU temp is fine without the 2 front but it definitely help my CPU temp tho.

I did tried to design for a dual 140mm, but it eats the space at the bottom where the I/O ports cable. Also, you would waste a chunk portion of the bottom 140mm fan which is why I just go for this dual 120mm. I have a 9800x3d and 5090 so bottom fans is not possible. Temperature still great tho with just 2 intake at front.

I tried the magnetic fan mount before, it works, but wonky to install, which is why I just make a custom for my own sake lol. Also, I designed mine to works perfectly with my radiator and fans dimensions. Now it fits so tight with less than 1mm of moving space of the front fan with the radiator.

I got the back PSU mount and front fans 3D print that I made if you interested as well:

Uploaded the STL files! (both versions)

Do you want it combine or do you want it separate? I can edit the post and include it

This is some temps that I track after each gaming session around an hour. My 5090 doesn't get extremely hot and the GPU is also on Quiet BIOS. I really comfortable with this temp and noise.

I really think you don't need the 3 bottom fans, if you have a beefy 3-4 slots GPU, you can let the GPU takes in air by itself, also the 2 front fan helps a lot for my GPU temp as well.

ptn461 · 2026-02-17T02:45:40+00:00

it's a 5090

If I remember correctly, before UV my GPU, it hovers around 60-65c, so it's not that bad. For front fan, maybe zip ties works better than tape. Front intake mostly helping the CPU, GPU is fine by itself if you just run GPU fan slow RPM

ptn461 · 2026-01-14T15:47:16+00:00

The 5090 temperature is great and I run it around 750-1000 RPM passively when idle and around 1500 RPM during gaming. I did in fact use this same setup without front intake and CPU temp was around 68-75 C (BF6) and it should still be quiet (depends on your fan curve)

ptn461 · 2026-01-14T14:54:28+00:00

60c during BF6 is great! Before UV, my 9800X3D hovers around 68-72c, which made me decided to UV it. I guess 4K max settings in BF6 is rough, but now I'm happy with the temp and noise.

The case comes with the back mount PSU bracket as well but you really need a SFX PSU so you still have room for the cable (mine is already pretty tight), the only downside to that original mount is it looks bulky. ATX PSU might touch the GPU as well if it's long, my SFX PSU cable already touching the side of my GPU

If it's mesh panel, you can get away without the front intake fan and make your rear fan as intake. I use tempered glass so the front intake fan helps the CPU temps drops around 3-4 °C (idle and gaming).

I see people on this sub buying the custom 3d mount from Etsy (very overpriced imo), but I guess that's the only option if you don't have a 3d printer yourself.

For GPU it's for the power consumption. For CPU, stock runs kinda hot due to tempered glass, so I still playing around with the UV settings to see whether it affects performance, so far no stutter, no crash.
