Question PSU fan ramps up to 100%

[Michael Valen]

Thanks in advance for the help.

I've made some posts on reddit/tomshardware earlier. I found out the faulty component is my PSU. Whenever I start my computer, after 1-2 minutes it ramps up to 100%. I've played with it before (because of a good headset and didn't notice at that time). Is there a temporary fix/safe to use? Could it be that the sensor/temp control is done for, and PSU is fine until the replacement?

The PSU is Corsair CX750M

does your PSU feel hot if u touch it after some time?

Not at all. The only part that feels remotely 'hot' is the fan, probably because of the load. Then again, the fan is warm to the touch, not close to unbearable.

fans are setup for 40C continous temperature
if u say its warm not close to unbearable..than it works as intended...
cleaned dust filters?
where is PSU taking air from? from outside of case or from inside ?

I've cleaned everything including the dust filters. The PSU is taking air from the underside of case. Never been a problem before (had the system for 6 years).

if its that old, some dust could be on heatsinks which prevents proper air flow

The PSU is dead. Rip Corsair CX750w you will be missed.
