Very loud noise on startup after PC is off for a long time.

post #1 of 19
Thread Starter 
Everytime I turn off my PC, keep it off for some 3-4 hrs and then start again, the rear outlet fan starts giving a sound not unlike an old car motor (but not that loud in magnitude). After turning on it keeps roaring like that for a while and after about 5 minutes the fan sounds go back to usual whirring sound (the "normal" sound that fans make). Anybody know why?

Sounds like one of the bearings are going out in the fan.

replace the fan, see if it goes away.

The fan might be dying, might have to oil it.

Some bearings are self lubricating. If after several hours it starts doing it, that would make sense.

Just try it.. new fan, $5....
