This is on an Athlon 1.2G, shuttle AK12, 512 crucial sdram. I am using the cooler that came in the retail box. My bios reports temps at anywhere between 32*-45*. Win98 reports 45*. But, win2K reports low 30*'s. I know there is usually a difference between bios temps and MBM5 temps in Windows. Any reason why my win98 and win2K temps are so different? Win98 and 2k report case temp of 22-25*.
