Why does nobody talk about PSU fan orientation in a basement PC case?
I just spent 3 hours rebuilding a client's PC in an NZXT H5 Flow and realized I had the PSU fan facing up instead of down. The case has a vented basement but I never checked the manual. I found a Gamers Nexus video showing that flipping it dropped temps by 8 degrees on the GPU. Has anyone else messed this up on a new build?

Eight degrees from flipping a fan?" That's a wild difference for such a small change. I would have never guessed it mattered that much.

Yeah, I was skeptical too until I tried it in my own setup. I flipped the fan on my PSU from exhaust to intake and saw my CPU temps drop by about 5 degrees under load. My GPU ran slightly warmer but nothing crazy, maybe 2 degrees. Worth doing if your case has decent airflow elsewhere.
