CPU Temperature Monitoring Discrepancy

[BoomerD]

I7-9700K processor
I've run Core Temp for years...maybe decades. I always thought it was the most accurate means of keeping track of CPU temps.
Recently, I added RiveTuner and HWInfo so I could monitor CPU and GPU temps during gaming.
I'm seeing anywhere from 15C to as much as 30C difference between the reported temps by the two programs. (Core Temp reporting higher)

Any idea what is going on...or why there's such a difference in reported temps? A couple of degrees, I could accept as "normal." Maybe one is measuring overall core temp and one is measuring one single (highest temp) core?

I think that for Intel CPUs, Core Temp measures Tjunction, which is going to be higher than just "CPU Temp", by, as you found out, around 15C.

It may also have an (incorrect) offset, in it, as well, depending on how recently updated your CoreTemp is. Do you have a version new enough to support your particular CPU?

Are you using the same sensor to get your readings? I normally go by what the processor itself reports rather than the motherboard reporting the processor temp.

I have the newest release of both.

Hell, I'm fairly tech stupid...I let the software determine where the temp is taken...but I agree...I'd rather see the temp as reported by the CPU itself.
