bios temp is -3, cpu fan is 3000rpm, wtf

I don't know why my motherboard CPU temp changed overnight from a normal 24-29C to -3. I didn't touch a thing. Noticed today when CPU fan was at full throttle and i checked bios. Comp works and all, my problem is the noise and the reason for it.

Hello mwtbdltr , I don't know either But dout it's -3*c ..
I would suggest checking/ reseating the cpu cooler as it is getting warmer for the fan to speed up and the -3* is incorrect for some reason...better safe than sorry

check your bios profiles for temp regulation , it might be misconfigured....I have seen strange things happen with power surges including bios settings changes ...

good luck
