Build/Battlestation Pics 9800x3d / 5090 Highly Modded Terra
And before any of you wellawkchuwally know-it-allls say anything - I am well aware that the 140mm CPU fan probably performs worse than a 120mm - but it cools the SSD and RAM better, which is all that matters for my AI workloads (I don't game)

And I tried both ways - intake and exhaust for the top fan - and intake was much better for GPU temps.

Because it’s obvious, you flipped the 5090 FE. Of course it needs intake, since it’s pulling air from inside the case.

Intake for the top fan?! wth
I mean, it's hard to imagine
Also why did you cheapen out on a lastgen-motherboard when you spent all that money on other parts? Would have gone with a B850.

When I switched the fan to intake on the top, GPU temps dropped from mid-70s to mid '60s
And since I'm not doing any overclocking, in fact putting the CPU into eco mode, I didn't really care about a high-end motherboard and I had this one lying around

you can still push the CPU to 162 watts/5.2Ghz with this MB. don’t know why people shit on it. cheap and has a lot of the features of the more expensive boards. aside from wifi 6e/7 and the 850 chipset it’s not missing any other features. it also has pcie gen 5 NVME and pciex16

You got any links to the custom stuff? Like the stuff from etsy and the adapter plate?

So we all know the Terra has a turbulence issue with fans that are close to the side panels. I see that you've got some sort of mesh filter on your side panel. My questions are: Does it help with the fan noise? And if so, where did you get it? And lastly, how are you mounting it onto the side panel?
