Power supply fan not running

[grevs]

Hi,
The fan on my power supply (atrix 650T) doesnt run.
can it be fixed or do i need a new PSU?

If it never actually works, well it may be something to take in mind, however if it worksfrom time to time, it may be a feature on the PSU to stop the fan when its not needed. Tried to get some info of your PSU but didnt got a thing.
