CPU fan failure

[Gary]

Okay, for as long as I could remember, my computer every know and then(hours/days) beeped, alerting me of fan failure. Though, it always stopped after a few seconds, this time it has not and when I reboot my computer it warns me of the fact. I really can't run to very long now, it can jump 20 degrees in a minute, meaning having it on for too long will cook my CPU.

I looked at the CPU fan and it seems when I boot, it spins for a second then stops and won't start again.

And because I have come to depend on my fellow lopers, I ask you; do any of you have any idea why this would happen? I haven't messed with any fan settings what so ever.

Check BIOS, check your fan, buy new fan if old one is broken. Really, there's not much else you can do.

Take it out and give it a good cleaning perhaps. Try spraying some canned air into the motor housing and such. Could make it better or worse or have no affect. Could even try submerging and shaking it in a bath of rubbing alcohol lol. Just make sure you let it dry out well though - rubbing alcohol still contains some water. You could prolly actually stick it in a toaster oven for a minute to dry it fast. I actually did this with a disassembled dropped-in-the-pool cell phone once and it worked great. (I used to work at an electronics manufacturer, and we regularly "cooked" boards to dry them out after they went through the washing process) . Though this process will prolly destroy whatever lubrication is in there, so yeah... maybe not.

If that works for you, you may want to try finding ways to keep the pet fur (or whatever) out of the case.

This sounds like such a horrible idea. Instantly makes me think of a house fire and burning plastic.

But if it works, then it works, but fuck if that doesn't sound absolutely horrid from first glance.

I had almost the same problem after I had built my computer, the fans span for about 5 sec and the the whole computer died. This is maybe not as your problem is but the sloution for me was that a fan plugin not worked correctly, so I just unplugged that plugin. So maybe you should try to replugg all the fan cables
Otherwise I would recomend to buy a new one as SotaPoika said.

Most plastics withstand the boiling temp of water easily enough. They may become somewhat "plastic" (lololol) but they wont burn. Contents will be hot. Allow to cool before serving.

If you can get hold of any propanol, that cleans an absolute treat, and dries off completely in minutes. Turpentine might just work as well, though they're both very aggressive chemicals and will attack certain plastics.

Or you could just buy a new board.

I'd suggest you just replace the fan. They're not very expensive, and I'd rather not work with the looming spectre of an unannounced shutdown.

I took a smaller one off an old CPU I found. It's not that much smaller, but it is about a thousand RPM faster.

Thanks guys for helping.
