I have an ASUS P5W DH Deluxe and am using Core Temp to monitor CPU temps.
I have tried to use the ASUS Probe II to monitor mobo temps, fan speed and voltages but I find this utility to be unstable and inaccurate.
Please recommend a better mobo monitoring utility
SpeedFan 4.31 and Core Temp are still the best choices. Use Intel Thermal Analysis Tool (TAT) to run both cores at 100% load for temperature testing. I've posted the following on another thread, so this may answer your questions.
Intel's spec for Thermal Case Maximum (Tc max) on the TM2 sensor is 60c. Temps displayed in BIOS, motherboard utilities and SpeedFan. 60c hot, 65c overtemp.
Intel's spec for Thermal Junction Maximum (Tj max) on the TM1 sensors is 85c. Temps displayed in Thermal Analysis Tool (TAT) and Core Temp. 75c hot, 80c throttle, 85c shutdown.
The scale illustrates TM2 BIOS and TM1 Core Temp typical offsets: BIOS + ~ 15c = Core Temp.
CPU Temps *C.
BIOS/CoreTemp
-60--/----75-----
-55--/----70-----
-50--/----65-----
-45--/----60-----
-40--/----55-----
-35--/----50-----
-30--/----45-----
I hope this helps to make sense of CPU temp alphabet soup. 8)
