Those cheap E-Machine fans(CPU and PS) really bug me as they apparently are of the pin-bearing type as opposed to the ball-bearing type.
Anyway, can these fans be lubricated to mitigate failure?
After blowing with compressed air, can I use WD-40 and NOT fry the system? Is WD-40 SAFE to use in a computer?
Do I have other lubricating options?
Fans are relatively cheap, but most can be lubricated. If the rotor isn't really loose (bearing worn beyond reasonable limits), the fan may give a few months extra service with some oil in the right place.
