for example,bios will tell you the cpu temperature is 55C,but in windows,speedfan or coretemp will give you both cores' readings,which are like 40-45C.
Though,speedfan has another temperature reading says "Temp2"which i have no idea what's that,but i believe it has the same reading as the bios "cpu temperature",the 55C one.So,which is the real processor temperature?

btw,my rig is as below

e2140
965p-ds3 gigabyte
micron d9 1gb x 2 ddr2 800
msi 8500gt 256mb

if that's the case,what's the "Temp2" in speedfan?It increases as the CPU load goes up,full load is about 76 - 78C.

i just did some modification to make my cpu fan less noisy,the core0 and core1 are about 78C full load,and the "temp2" reports a shocking 93C!!i'm getting worried what that really is.

fan only la..if liquid cooling my mum will go berserk la.
