Why you not use Core temperature when overclocking.

post #1 of 5
Thread Starter 
I've spent an hour installing a little temperature probe onto the copper base of CPU water block.

Now I've always used Core temperature for overclocking and not CPU temperature but after testing it seems that CPU temperature is the REAL temperature.

At the time of me writing this ASUS sensor probe is reporting that the copper base plate on my CPU block is at 31c

HWMonitor is reporting CORE temperatures of 23c across all 6 cores which is impossible as my CPU can't be cooler then the copper base plate that's cooling it.

Now HWMonitor is reporting a CPU temperature of 36c which seems more likely to be true with my CPU being 5c hotter then the copper base plate cooling it.

So I'm off to check me overclock temperatures now and lower it if necessary

Old news, it's been known since release that the Thuban core sensors are about 10c too low, and you should just look at socket temps.

The core temps aren't measured with sensors, they are a just an estimation that is gotten from an equation and aren't accurate.

All the Thuban chips have core temps lower then CPU temps.

Most other chips have core temps higher then CPU temp.

Give this thread a read, it helps explain about core temps http://www.overclock.net/amd-cpus/93...out-1090t.html

I only use CPU socket temp since I no longer have core temps since the unlock.

It is my understanding that socket temp is generally greater than core temps. I am not going to check this on my machine as that would require putting the CPU back to a dual. But there are four (or more) cores adding heat to the CPU so why wouldn't the CPU socket temp be greater?
