I've got an MSI board and some people have told me that its temperature reading's are rather farfetched. Using "Core Centre" I get: -
CPU - 48C
System - 38C
Seems a little toasty, But apparently MSI boards label their temp sensors wrong.
Apparently the so-called "CPU" temp is read from a sensor INSIDE/NEAR the core of the cpu, and the "system" is the ambient temperature on the cpu itself.
Dunno who to believe to be honest....
