I'm sitting here looking at the operating panels of SpeedFan 4.43, Core Temp 99.8, Real Temp GT 3.60.
Core Temp is showing the four cores ranging between 27c & 32c
Real Temp is showing 27 to 31
Speedfan is showing one CPU at 47 and one at 128c!
My guess is still a bad sensor. And I'll bet SpeedFan is using readings from it to show 128c.
