[SOLVED] Hybrid PSU Positioning

[newtothiscomputerthingy]

hi my mans,
CASE: NZXT H710 (the hot box)
PSU: 850 W ASUS ROG Strix (not the thor Asus stuff the like stripped down versions)

I've got me PSU in hybrid because everflow fan is well, loud
I read the manuals etc and no specific mention of where to position this hybrid PSU - I only inquire as when in passive mode you'd think it be better to allow heat to rise and what not, but obviously its gonna be passively going into my rtx card and heating that guy up which is already idling high temps due to Nvidia Broadcast and the h710s average airflow. they will also fight for that same airflow as the fan will be pulling from the GPU's source.

the issue is with fan down, and internal components being up means the heat just stays and rises back into itself until the fan eventually turns itself on - which i felt on the sides of the psu as being nice n toasty after relatively short use. max operating temp of 50 C should mean even in the hot summer it should be a'ight but you never know.

in short, where should i position it in your guys opinion and do you think that good old ASUS parts will survive the heat of hybrid mode?

thanks my mans

The exhaust from the PSU shouldn't be going into the GPU. The heat should be exhausted out the back of the CPU, not up or down.

The heat will be exhausted from the same no matter if the intake fan is up or down (at least when the fan is on; if it's not, then it's usually a low enough temperature that the heat is fairly negligible). The question is if the PSU will get more ambient air with the intake up or intake down. Generally, it's preferable to have the fan down so that the PSU has its own air source, but it's not better in all situations. If the ventilation holes on the bottom of the case are insufficient or there's insufficient height clearance from the case feet or the case is on a dusty floor or carpet, then it may be preferable to have the fan up.

If you're worried about GPU temperatures from PSU orientation, the most logical course of action would be to test this on your own.
