Power Supply Fan Problem

[quakeworld]

hi. the power supply fan in my tower needs a little help in starting. i would get a pen in there and give the blades a 'push' for the fan to start spinning. even then i think it's not spinning as fast as it should. i tried using a blower to get rid of the dust bunnies but the problem persists. i was thinking of maybe spraying some WD-40 on the motor thing but not sure if this is safe. would appreciate advice on how to fix this as i don't want my PSU to overheat. thanks!

It would be kinda helpful to know what your power supply is. How long have you had it?

That would be helpful. Generally speaking though, it doesn't sound like something that you'd normally be able to fix by yourself without opening the PSU, which is only recommended if you know what you're doing with it.

There's a canned air/spray lube solution that you can buy that might be worth a shot if you don't want to open up your power supply and void your warranty. Just get the spray nozzle in as close to the inside of the hub as possible and spray away. The lube is non-conductive (the stuff is made specifically for hot electronics) so don't worry if it gets on other components.

It's made by DeoxIt and a can of it is under $10. Make sure you get the DeoxIT with the "rejuvenator" because there is also DeoxIt that's just contact cleaner.

Is it a stock fan or did you replace it ? If you replaced it for a lower RPM fan, its gonna require a little more amperage to get it started at the same vDC. If you didnt replace the fan, your PS might be going out or your fan is slowly dying.
