I recently changed my psu to CORSAIL sf1000, and noticed some difference. I did not change any of the airflow setup, but the up front fan actually exhausts COLD airflow now, other than hot airflow like before with a shitter psu.
I think it's because the SF1000 is a much cooler psu. But, the real concern is since it's venting out cold air, does it really help at all with the cooling? In picture 2, i tried to cover part of the side mesh with a sheet of paper, intending to create a vential airglow to help the GPU exhausting hot air. During my test, this change did make the up front fan exhausting a little warm air, but the overall temperature didn't make much difference.
I'm wondering, if i change the back fan and cpu cooler fan to intake, and take away the up end fan, will it make a big difference? I guess the dust will be more noticeable anyways.
My build:
CPU:i7-10700
GPU: 9070xt
PSU: CORSAIL SF 1000
Case: NR200
Temps: CPU:50-60 idle, 60-70 gaming GPU: 60+ gaming, memory 90+ gaming ( known for hot GPU memory, but i think it's fine)
