CPU Fan Runs Loud

June 5, 2011 at 10:41:30
Specs: Windows 7, 4gb
The PSU on this computer got replaced by some local computer shop, and when we got it back the CPU fan was running very loud. I cleaned out all the dust, but it still runs loud.

Should I replace the CPU fan or is there something else I should check out?

"Should I replace the CPU fan..."

Yes. If you're sure its the fan and you've cleaned it and it still runs loud, then likely the bearings are affected.

If, by "loud," you mean a squealing or grinding sound, then I agree with T-R-A about replacing the heatsink/fan unit. If the fan is just louder than before, you might want to check with the repair shop that worked on your PC. If they replaced the CPU fan with a smaller one, that might explain why it's louder. As a general rule of thumb, the smaller the fan, the faster it has to spin to accomplish the same cooling, which usually means a louder sound.

Also check your temperature in your BIOS or with a monitoring program like Speedfan, if your computer is running hot, that could explain the louder fan due to the higher fan speed. If your system is hot, you need to find out why, or take it back and get them to fix it right. If the system is running hot, it could be incorrect application of thermal paste, incorrect or overclocked BIOS settings, additional software running in the background (probably not good if they did not install something for you), CPU fan plugged into the wrong motherboard connector, and possibly others.

You have to be a little bit crazy to keep you from going insane.

I replaced the fan and it isn't as loud as it was, but it's still louder than when we bought it.

We contacted the repair shop and they said what they did had nothing to do with it.
