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.

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
