squirrito Posted August 18, 2020 Share Posted August 18, 2020 Recently my newly built PC has been unstable, frequent BSODs with no cause that I could determine. At random, I noticed the Zero RPM mode on my PSU was on. I turned it off. Suddenly the PC is behaving again, at least for the past few hours which is more than I've been experiencing. Can the Zero RPM mode somehow cause system instability under certain conditions? Could my PSU be faulty? It's more or less brand new, a couple of months old at most.

It SHOULD turn on if the PSU gets too hot, but who knows. It's hard to say without knowing anything about your build. Like what you're powering, what your case is, how's the ventilation, how is the PSU mounted, fan up, fan down, etc. Link to comment Share on other sites More sharing options...
squirrito Posted August 18, 2020 Author Share Posted August 18, 2020 It is mounted at the bottom of a Fractal Design Meshify S2 case in an upright position, so the fan (which I believe is an intake) is at the bottom of the case. The PC sits on the floor, but the ventilation in the case and behind this PC is reasonable I would say. The PSU is powering Ryzen 3700x, RTX 2080 Super, 32GB 3600 Mhz ram, AIO cooler, Crosshair VIII motherboard, an SSD and an HDD. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted August 19, 2020 Corsair Employees Share Posted August 19, 2020 Hmm.. Shot in the dark, but you could just try the PSU mounted fan up to see if the behavior changes? Because then the heat rises up out of the PSU as long as the fan isn't spinning. Link to comment Share on other sites More sharing options...
