CPU Temperature is the temperature measured by a remote temperature sensors part on the motherboard near the CPU.

The most common implementation uses a temperature sensor part external to the processor with the CPU Thermal Diode Anode (+) and Cathode (-) connections to it.

CPU Diode or Core temperature is the temperature measured across a temperature sensitive diode on the processor die.

Let's get some terminology straight from Lavalys' KB: Make sure the heatsink is properly seated with thermal paste. If the fan is very cool and the processor is reporting very hot, I would first suspect the connection between the fan/heatsink and the processor package.

Heatsink's need to be VERY firmly pressed against the CPU to conduct heat.

Intel CPU's can run SUPER HOT (upwards of 95C) and still be stable.

Only thing I can surmise after 2 years of use was that, over time, the heatsink pressure on the CPU gave way until the heat began to be ineffectively conducted. The heatsink is a Masscool 8Wa741, which screws into a standard position on a mount on the back of the MOBO. Even though the thermal paste was visibly flattened out every time I removed it, it looks like the heatsink was still not pressing hard enough on the CPU to effectively conduct the heat. I swapped it out with the stock heatsink/fan and lo and behold the temperatures returned to the normal 35C-50C. My suspicion in the heatsink was suddenly renewed. I switched the processor out with another one and got the same obscene temperatures with the new processor followed by a heatsink that was cool to touch. Should I call intel and tell them to send me another E6850?

What angers me is the false temps force the CPU to artificially throttle from 3GHz down to 2GHz and my CPU fan is cranking at full force all the time. Reverting hasn't been known to help from what I've read. Sidenote: the BIOS has the latest version so no option to flash there. (LOL)Īt this point, I'm thinking no doubt the cpu's sensor is wrong. Then I ran REALTEMP, which is supposedly more accurate and it told me the CPU was at 104 degrees.

The area near contact with the CPU was slightly warm but not hot to touch. The heatsink was completely cold to the touch. I then immediately shut it off and opened the case and felt around. I let it sit at 94 degrees for 20 minutes straight and the computer didn't even flinch.

Ran the stress test and it went up to 94 degrees before being 100% throttled. After powering it up, there was no noticeable change in the temp - ideling at 74. I polished the surface, re-applied some new paste, and reseated the heat sink. I removed the heatsink and cleaned off the original thermal paste (which was somewhat crusty). So that leads me to believe it's a CPU seating issue (even though I used thermal paste to seat it two years ago when I built the machine) Is there such a thing as a CPU temp sensor showing the wrong readings? To top it off, I removed the cover of the box and felt the cpu heatsink and it wasn't even warm. System remains stable though.įor over a year now, my CPU has run very cool (40's) with a large commercial copper heatsink/fan that I bought separately. When I stress-test the machine, the temp goes up to 91 degrees and the CPU actually throttles. Everest Ultimate is suddenly telling me that the CPU temperature (and core temps) for my E6850 Core 2 Duo is 72 degrees Celsius.
