CPU Fan is on high all the time by alegator on 12-26-2009 at 06:29 PM
I never had this issue in the 8 years I'm using this PC. I left home two days ago so I left the PC unplugged. Today when I came back and powered on the PC everything seemed normal but after about 5 minutes of using the PC the CPU fan started spinning at high RPM and making the normal loud noise when this happens (sounding like a hairdryer on high). Since then (about 5 hours already) the CPU fan has kept working at high RPM and I was unable to set it to low speed. I opened the tower and checked that all cables and heatsink is tight. Unfortunately there's no setting in the BIOS that controls the CPU fan.
What could be causing this? Will replacing the CPU fan by a new one fix this? Thanks.
MY SYSTEM: Dell Dimension 8200, P4 3.06GHz CPU, 2Gb RDRAM

8 years? Have you ever cleaned it?

Do you have a hardware monitor option? Check the temp isn't actually too high and that eliminates it being a heat issue and points towards it being the CPU fan on it's way out

I cleaned the CPU fan thoroughly and for the last 6 hours has been working fine, at normal speed and without noise. So I guess the dirt was the issue. Thanks everyone for your replies!
