Do you have a manual for the mother board?? Sounds like someone forgot to plug in the fan or you didnt say if the fan was working on the microprocessor or not?? If its not working then the plug for the fan should be right by the socket fore the processor. If it is working then theres a setting in the bios that has to be reset. I would take the board to or ask the person you bought it from about it. Did you buy the board with a case or all pieces separate? Good Luck

My computer was in the shop for something unrelated to this problem and now that I have it back it (the cpu fan) sounds like I'm running a vacume it's that loud.

Hi Tim,

I can not say for sure that this is whats happening, but from your description, it seems logical.

After work is done on a computer, sometimes one of the ribbon (data) or power cables isn't completely secured. It can move around within the case, especially if it is transported (like back from a shop).

On occasion one of the cables comes in contact with a CPU fan (or any of the fans in a computer).If it does, the noise they make is horrendous.

Fortunately, the fix is easy. Get a flashlight and a screwdriver.
  • Open the box.
  • Switch the computer on
  • Locate the noise source if possible paying attention to the areas around the fans.
  • When you find it switch off.
  • If it was a cable just relocate it out of the way.
If this turns out not to be the problem, please comment back with more detail.

Best regards

When i boot up the laptop i get a message 'Main Fan Error' the fan runs on start up then stops just before i get the error message. Fan will not restart... Joseph


This message means that the fan on your CPU (processor) is failing or has failed. This is not good because if the fan on the CPU fails your CPU will overheat and cause your machine to lock up and become non-functional till it cools down and then the same cycle will repeat till the fan is replaced.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Dell Dimension 3000 CPU Fan does not run

I agree with both of you. As long as you are not experiencing any heat event (shutting down and rebooting) just ignore the error message. If the fan is on and running at a fair speed, you shouldn't have and problems.
Now should you start to have heat problems, don't boot the computer until you have a larger CPU fan in place...and too you may be able to add an additional fan to the system for reassurance. the added noise is worth the security of not having a CPU meltdown.
Those large 120 are very quiet and move air, if you can find a place to hang it.
Good luck, hope this helps. please leave rating -thank you kindly

Cpu fan error

Make sure the cpu fan is plugged in and to the cpu fan connector on the motherboard.

Check to make sure the CPU fan is plugged into the motherboard CPU fan power pins. Should be a 3pin port on the motherboard near the cpu with a white piece of plastic on the one side of it to show you are to plug in the cable correctly.

See if the fan spins at all on start up, or even when the computer is off, spin it with your finger and see if it gets hung up anywhere while it spins.

Cpu fan noisy/chip fan fail error messages


Yes. This sounds like a fan issue. The noise often comes from bearings failing within the fan. Also, a failing bearing can make things harder on the motor as it brings the fan up to speed. This is likely the reason that you see increased warnings during the fan speed check while booting because it comes to speed more slowly as bearing wear increases.

I give this a 90% chance that your CPU fan is causing the issue. Since a decent CPU fan will cost you ~$20 online, it's not much out of your pocket if you happen to uncover another culprit.

I'll keep an eye on this post. Let me know how things go.

Cpu fan noisy /chip fan fail

You must buy a new CPU Fan. You can get them HERE or a zillion other places on the Internet. You need a Socket 939 type fan that will handle your cpu speed. If you need help installing it, it may be in the manual. You can read the manual by clicking on the picture of your MB at the top of this post and then scrolling down.

Hope that fixed ya...

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.
