CPU fan not working

My PC has been switching off randomly and I suspect overheating. When running it with the case off I noticed the CPU fan wasn't running. The fan DOES work when connected to an external power supply. I can't find anything in the manual or BIOS about settings for turning CPU fan on at certain temperatures.

Any advice?

    Thanks, but the problem is NOT with the fan - MAYBE the PSU but I doubt it. With a bit of fiddling I was able to connect the CPU fan to the system fan motherboard jumper instead of the CPU fan jumper. Now everything seems to be hunky dory - but I'd still like to know why the CPU fan jumper wasn't turning on the fan. Some systems have a BIOS setting that can control fan speeds based on temp, but I can't seem to find one on this system.

This problem is due to your Powersupply! Get your powersupply checked and if necessary get it replaced with new. Avoid repairing.

usually the computer switching off randomly can be caused by overheating issues. Make sure the cooling fan over the CPU is working, if not you'll have to replace it. You can use compressed air to blow away any dust accumulated into the computer, to ensure maximum cooling efficiency. Another culprit could be the power supply unit (PSU) and you should try replace that (costs less than a new motherboard). If you specify what kind of computer (desktop, notebook) you have and the model I can be more specific. Let me know if this helps you, bye

My ibm thinkpad r51 laptop keeps shutting down randomly

Check your heat vents and make sure they are free of dust. You could also have a CPU that is overheating. In that case we would take out the CPU, renew the thermal and replace. A short term solution and by far the least expensive would be to purchase a laptop cooling fans. They are powered by your USB ports and they cost anywhere from $30 -$50. We use them quite often on older laptops and owners who are cash strapped.

CPU shutting down.

Hi MonaMona,
Replacing a CPU fan is easy, but be carefull, the CPU will have old thermal grease on it, so unlatch the CPU at the same time you take the fan off. Because the CPU will come up with the fan, so unlatch the CPU pins, to release the CPU pins, when taking the fan off. And when putting the new fan on the CPU, & the fan nust be smaller then 80mm, the sell just CPU fans. Make sure you put on thermal grease on the CPU, so it won't over heat & will protect your CPU, also don't cake on the grease. Put on a small amout & spread it on the CPU thin. Let me know if that does it for you.

Good Luck with it.
