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?

Re: CPU fan not working

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

I have a hp slimline 3100. the cpu fan runs fast everytime i open a program or play a cd. it speeds up the slows down. sometimes it runs really fast, then the computer shuts down. whats going on?

This is an indication of overheating within the PC. Open the PC case and clean all the air vents. Take the heatsink and fan off the CPU and give it them a good clean. Put the heatsink and fan back on to the CPU and start up the PC. check that the fan on the heatsink is running smoothly.
Also, make sure the vents on the power supply are clear and the fan on the power supply runs well.
If you go into the BIOS setup, you may be able to monitor the fan and the CPU temperature.

Sounds like the CPU is overheating. The usual cause is the CPU heatsink and fan need cleaning. Take the side cover off and have a look see. Also, it's possible that the heatsink may have come loose and isn't making good contact with the CPU. In either case you may need some CPU paste. Also check any case fans to make sure they are working.
After checking those things, suspect the power supply, memory, and possibly the hard drive.

It is possible that the fan of the CPu is not working properly anymore.

There are several ways to determine if overheating is indeed an issue.
Open the case of the computer and place a fan next to the case, so that it'll keep the temperature down. Aiming your aircondition at the insides of the computer also works.
If the computer works as normal, then you'll have to replace the CPU fan.

You can also look up the message of the blue screen in Microsoft Knowledge Base.

Hope it works....

The case fan should start running as soon as you turn on the computer. I would replace the fan with a higher capacity (CFM). If you have a case that can take 2 case fans, I would install the send fan. Also with the case off, check that the CPU cooler fan is functioning. With the quick shut off, I would suspect that the CPU cooler fan is not functioning. I could be impeded by dust. Vacuum and blow out any dust on the motherboard, fans and battery fan while you have the case off.
This should aleviate the shutoff problem due to overheating.
Let me know if this solves the problem.

CPU Fan not working

When the cpu cooler isn't working the cpu may destroyed by overheating. The cpu overheat protection makes your computer to shut down. Open the case and double check that the cpu fan cable is connected to the motherboard, at the proper connection point. Maybe replacing the battery, this cable ejected.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

Boots up but only runs for about a minute. Then fan runs at full speed constantly with no video. Also front panel popwer switch appears shorted. i.e as soon as you plug in the PC starts

Very well could be overheating or powersupply problem. Most Definately Hardware related. You can try opening up the case and blowing air into it from compressor. (Make sure to do this outside away from clean items). Also, check CPU fan and heatsink to make sure fairly clean. CPU fan may also be old and need to be replaced. Don't put case back on and try again. Look at CPU fan to see if moving (or struggling). If computer stays on longer then CPU fan most likely the problem. If off in same time as before then most likely the main power supply problem, in which case the only way to check this is to replace the power supply. Hope this helps, Best Regards,

Programs shut down at random

Have you checked in your case to see if all your fans are working? May be a heat problem in power supply, CPU. Get this software and install to check the actual temps on your motherboard.

This is the free program I use.

Here is also a website that talks about overheating problems and solutions

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.
