I recently purchased a GIGABYTE GA-MA790GP-UD4H with a Phenom II x4 940 processor. I applied AS5 thermal paste (properly removing the existing thermal grease from the stock heat sync). This issue I am having is determining the correct temperature of the CPU. BIOS and Easy Tuner 6 (The temperature monitoring software that came on the Gigabyte disk) show the CPU temp @ around 30-31C on Idle. Other software I am more accustom to using such as Speedfan, HWMonitor, and AMD OverDrive are all showing my CPU @ between 43-46 IDLE. There is a 13-16C difference between what BIOS is telling me and what Speedfan is telling me.
Has anyone else had this issue, which piece of software did you find to be accurate? I would like to believe that my CPU is hovering at 30ishC... I already removed the heatsync once to make sure the thermal paste was applied correctly, and it was perfectly so I removed everything and cleaned everything again and reapplied. Since I am receiving the same temperatures each time, I can rule out an issue with the application of the thermal paste.
Thanks!
