I know people r gonna call me stupid but i pulled off my heat sink from my dual core athalon II cpu and put a pretty strong old fan that i found over the cpu because i was just testing to see if the guage in my case would work all these things exept the cpu and mother board were found i bought the motherboard and my friend gave me the cpu so i tested the guage and i ran the computer for not even a minute and it was at max on the guage so i turned it off and felt the cpu and it was burning hot so let it cool down and restarted the computer and turned on the bios and let it run for a minute and a half with the fan on and it got to 100( i left it on till then out of curiosity) my motherboard was at 30 then i turned it off now im here my motherboard is a msi 970ag46 sorry for makin this so long
