Which Temp Monitor Do I Trust?

post #1 of 11
Thread Starter 
I'm currently using TAT & Core Temp to measure my temps whilst running Orthos and right now 2 hours into the test my reading from TAT is 54c, but my reading from Core Temp is a full 3c higher at 58c.

Which one is the correct temperature? Or are they reading teh temps from different places?

Ta

Joe

It seems to vary when TAT reaches 54c, anything under 54c on TAT and Core Temp reads the same temperature but when TAT gets to 55c Core Temp skips a few degrees!

They both are designed to read from the sensor on the cores....however, they use different algorithms to get their final value.......generally speaking, I would use the higher value and err on the side of caution.......however, I have heard that TAT is usually more accurate than Core Temp......

I heard the same about TAT and I trust TAT more as Intel made the CPU!

Thanks for the info guys

Just a warning.

As you are using two applications to read from the Core 2 Duo sensors the results may not be correct

The sensor should only have one device/application attempting to read data from itself. Using more than one can generate inconsistent values.

I suggest you use either TAT or CoreTemp, but not simultaneously

Ahhh.

Cheers Manual, that would make sense! Which one do you use?

Yea The Manual is right. What you should do is use CoreTemp at 100% for say one hour and then reboot leave you PC to cool down and then try the same with TAT @ 100% for 2 hours to see if they are the same.

I use the Intel Thermal Analysis Tool as it has generated more consistent results that agree with my manually installed CPU probes near the CPU core (embedded under the heatsink, a bit risky).
CoreTemp seems to be 1-2C off, most likely due to the algorithm used. Could also be a Analogue > Digital read/write error.
post #9 of 11
Is CoreTemp normally 1-2c higher or lower than TAT?
