Hello everyone,
I recently upgraded my personal system, going from AM4 to AM5, 5600G to 7800X3D, Cryorig H7 to Thermalright Phantom Spirit 120SE, keeping my Sama (sold as Intertech here in the EU market) IM01 case.
Currently my cooling setup is as shown in the picture:
Fresh air is pulled in from beneath by 2 Arctic P12s, blasting the GPU. The GPU itself spits the hot air out whichever way it can (a fair amount out the back actually). GPU temps are phenomenal.
The CPU pulls fresh air in from the rear and then essentially blasts it at the underside of PSU. There's an Arctic P12 up top that also exhausts hot air, but it can only do so much considering the limited space.
The PSU is essentially an isolated loop, pulling in fresh air through the vents in the front panel, and then exhausting it out the top.
So far, CPU temperatures are fine. The most CPU-intensive game I own is Cyberpunk 2077, and the CPU hovered between mid 50s to mid 60s °C, with occasional, very short spikes into the 70s. I am running it with a -30mV undervolt, and swapped out the stock Thermalright fans for Noctua 2K Industrials, so I'm not too concerned about the CPU, but rather the PSU. During a gaming session (Destiny 2, ~2h) I touched the underside of the PSU, which the CPU is barraging with warm air, and it was warm to the touch, as expected. Not hot, but "phone under heavy use" type warm.
What I'm wondering is whether you would flip the PSU around so the fan is facing into the main chamber, rather than having it as a separate loop?
On one hand, I know that PSU components don't immediately explode as soon as their ambient temperature exceeds 22°C, and afaik, the PCB inside the PSU is mounted on standoffs that separates it from the bottom of the enclosure. That means there's a layer of air between it and the surface that I'm effectively heating with my CPU exhaust, plus there are very few, if any, components on the underside of the PCB. Thus, chances are the actual components aren't really being heated much by the CPU exhaust.
On the other hand, back when top-mounted PSUs were the norm, you'd run them fanside down a lot of the time. Usually this was cause the case didn't really have an option for the PSU to breathe when mounted fan-side up, but additionally, it provided some extra exhaust. However, in my case, the PSU would only be getting pre-heated CPU air blasted straight into it, which is a bit different than the passive airflow from say a downdraft Intel stock cooler.
Since I've no real way of monitoring inside temps of the PSU (and monitoring individual component temps would be opening a separate can of worms entirely), I don't really know how it's faring, and whether it's fine as is, or if I'm cooking all my components alive
As such, would you flip the PSU around? Or keep it as is?
Bonus question, do you think adding an 80mm rear intake would help CPU temps any? Considering there is only maybe 3 inches of distance between the back of the case and the CPU fan.
Would be interested in hearing y'all's inputs and thoughts on this. Cheers

I settled on this layout and asked my question using this current layout because it offered improved CPU thermals, I just wanted to see if anyone would be alarmed at me "blasting" my PSUs underside with CPU exhaust air
