CPU fan went crazy after resetting BIOS Tags: Motherboards BIOS CPUs Last response: November 12, 2013 5:39 AM in Motherboards Share steggen October 23, 2013 12:27:14 PM In another thread I got the suggestion that I should reset the BIOS, so I removed the little cap beside "clr cmos" on the motherboard and put it back. But when I started the computer again the fan on the motherboard goes on full speed and makes an unbearable sound. It didn't do that before. What has happened and what can I do about it? (Btw. Should the cap over "clr cmos" cover all three pins or just two of them?)

The settings were on "Full ahead" or something like that. I put it on "Automatic" with target degrees of 50 and target level of 5. The sad thing is that it's still making a lot of noise. Do you or anybody have any recommendations for the settings? m 0 l Can't find your answer ? Ask !
