My old PC's fan stopped working recently, so I replaced it with another. Now, when I try using the PC, it restarts after about half an hour, and gets really hot (to the point where I can smell it). I know the PC uses two fans, one of which is operational, but the the one I replaced still doesn't work for some reason, even though it's a new fan. Any idea what the problem could be?

Thanks.

Check the fan settings in the BIOS.

How exactly? And what am I to look for?

Do you know what BIOS you have?

Is this the case fan or the CPU heat sink fan?

How many wire are on the new one, and how many were on the old one?

How do you have it connected, to the motherboard or a molex connector?

I know this sounds stupid. Is the fan turning in the right direction?

Budapest: I don't know what BIOS I have, but I'll try to find out.

dc3: It's the heat sink fan, and they both used a 3 pin connector. The fan is hooked up to a port on the motherboard. It looks like a molex connector, but has 3 pins.

garmanma: The fan doesn't work (I can't hear it), so it wouldn't be spinning at all.

Hi,
Have you checked the motherboard for any broken connections? I don't know if this is true, but apparently sometimes the motherboard can warp very slighty due to exessive heat, and tause the copper connections to break. Get one of those things that goes "BEEP" when you touch the two ends together to check for an electrical current. I forgot the name of it, but who cares?
I hope this is'nt the problem, because it spells disaster for you if it has.
