Temp difference between CPU and Core temps

Hey guys. Read my sig for specs on the system. Its up to date.

I have noticed with PCWizard07 that it will show my CPU temp at around 35*c-38*c at load, but when it shows the individual core temps, they are usually in the low 50s. Typically one is a little higher than the other, and I know this is normal, but what is the deal with the cores being nearly 14*c hotter? Ive taken a mini straight edge and checked the flatness of my water block as well as the CPU Heat spreader and they are very very flat.

Help?!?
 
What you have to determine (through documentation or email to support) is what is PCwizard actually reading with reporting these temps.

I will hazard a guess.

The higher temps are the actual internal core temps from the DTS circuit embedded inside the cpu. These are highly accurate and if you run some loading software they should almost instantly change with changes in load.

The single "cpu" temp is probally from a sensor (thermister) mounted on the motherboard in the socket "well" under the cpu as will read significantly lower and not as quickly subject to change in cpu load as the above temps. IMO if this is in fact the case, this temp reading is of little or no use.
 
So with a Core2Duo and the Gigabyte DS3 v3.3, what is being monitored in BIOS? This temp in bios is even lower than in PCWIzard.

When I get home from work, I will look into downloading CoreTemp and see what it has to say. It just seems that so many programs all show something way different.
 
Coretemp may crash your machine as it does mine. RMClock is a little known util that accurately reads core temps from the DTS. Try it and report back.
 
LOL, as I was saying... there are so many out there.. I dont know which to believe anymore.
 
RMClock. If you want convincing proof, read this thread paying attention to uncleweb's instructions to read your DTS directly with crystalcpuid. You'll find that RMC is accurate.
