CPU Fan error message at boot up

Slap · 19 Nov 2006 at 10:22

I keep getting this CPU Fan as failed message on startup, if I go into the Bios, I can see that the fan speed is extremely low(300 RPM), but has soon as I start up Windows and check with Asus Prob it is back to normal speeds(1900 RPM)...

Could it be that the fan has dust on the inner mechanism and takes a little while to kick in? Faulty fan? BIOS gone a little weired?

Any suggestions on how best I check the fan?

Cheers

When i had my Gigabyte K8NXP-SLi i used to get the fan fail warning sometimes and the cpu fan would be completely off, but only if i had set it to report fan failure in the bios. With the fan fail warning off the fan never stopped and worked fine. It was a bit strange and i ended up plugging the fan into the psu just in case.

It might just be some random thing like what i had. Plug the fan into the psu and see if it still stops running.

When I changed my fan for a quieter one, there was a note in the manual for it that this may happen as it detects the lower speed as a fault. Luckily never happened to me, but mabye thats what your getting :confused:

I had the same prob with the freezer pro.
I put the fan to performance in the bios and that helped.
