Can you turn off PSU fan?

Re: Turn off power supply fan This is a really bad idea. There are PSUs that are designed to shut the fan down when at low load, but PSUs that aren’t designed to work this way won’t have the passive cooling capacity to keep critical components from overheating.

How do I test my PSU fan?

Why is my power supply not spinning?

So, the main reason why your PSU fan won’t spin even when you’re under 40 percent load, is because the fan is designed that way. It won’t turn on unless your PSU needs to cool down and the load on your system has exceeded a certain limit. Another factor that affects the fan is the temperature of your PSU.

For bottom mounted psu’s, the fan intakes from the bottom and exhausts out the back in its own system. It does not mix with the case flow at all. So if you’re talking about overall case flow, it’s neither.

How do you replace a power supply fan?

To replace a modular power supply fan, remove the mounting screws securing it in place, disconnect the power connector and remove the fan. Connect the new fan and secure it in place. CPU fans may mount to the CPU and socket on the motherboard, may fasten to a fan mount or fasten to the case and channel air flow to the CPU with a shroud.
