PSU fan not spinning

Hi I just bought Corsair SF750 and noticed the fan won't spin throughout entire usage of the pc and gaming. Every time I switch on pc, the PSU fan spins for few seconds and then stops, and never spin again. Is it normal? It's not spinning even during heavy gaming. Edited by kkl

That specific PSU has a zero RPM mode and will only spin up the fan when necessary to actively cool the power supply. You most likely aren't pushing the unit to the point it needs to actually spin up the fan.

 

I tried with Unigine Heaven Benchmark 4.0 for 15mins and also gaming for 2-3 hrs, did not see it spin even once. What's the best way to push its limit, to test if the fan is working?

Without knowing your hardware specs, we've got no clue what to tell you.
