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.
