It has flame icons next to "Temp1", "Core0" and "Core1" - I assume this can't be good.
When I build the system a few months ago, I did apply a generous amount of Arctic Silver Ceramique Thermal Compound to the CPU, installed a COOLER MASTER 92mm CPU Cooler, a Scythe 120mm Case Fan, and my Thermaltake 750W Power Supply has one or two fans.
Im not sure but your speedstep/powersaver thingy in BIOS may be down clocking your multiplier when your idling to save power. My 965P-DS3, if I turn it(I forgot what "it" is called) on in the bios, when idle CPUZ shows my multiplier at only 6 instaed of 9. Doing the math: 6x266= 1596Ghz. So that gotta be it.
IF that 62C is idle then your HS is probably not mounted properly. If thats a load temp and youor running witht he stock cooler then that sound about right.
I had this same problem, what I did to fix it was disable C1E and EIST and for some reason I had to turn the bus speed tuning to manual and 266 (for some reason it was on auto and 200 and still showed I had 2.13ghz), doing this fixed my problem and now cpu-z displays correctly.
