CPU Fan Failed

post #1 of 10
Thread Starter 
Well, I installed a new CPU heatsink/fan, it's a Masscool aluminum with an 80mm fan. Put it on an Athlon XP 2500+ CPU with an A7N8X-E Deluxe mobo. (didn't have the CPU overclocked to be safe.) Heres what happened:

Booted up fine initially, then when windows was starting to load the fan stopped. Touched the Heatsink and it was very hot, so I turned off the power quickly and waited for it to cool down. I took the cooler off and put the stock AMD back on, booted up, and it said "CPU Fan Fail". Hmmm. So I put the fan power connector on a case fan connection on the motherboard and it runs fine. But everytime I boot up it obviously says: CPU fan fail.

Did the Masscool blow a capacitor or something? Not sure what's going on here but the CPU fan connection just plain doesn't work now. Any Ideas, fellas?

If the mobo doesn't sense a fan on the CPU fan connector, it will display CPU Fan Failure

When you clear CMOS it will probably revert to normal.

To clear the CMOS do I take the little battery out for a while? What does clearing the CMOS actually do and why might it fix my problem?

Just reverts all your settings in the BIOS back to their defaults. It might be enough to make the CMOS "Forget" that there was ever a problem with your CPU fan.

just so you know, most motherboards have three pins with a jumper on two of those pins, right by the battery. to reset the bios, simply move the jumper over by one pin for three seconds withe the pc off and then switch it back

So should I take the little battery out or move the jumper pins?

It's easier to just move the jumper.
