Question CPU Temp vs Core Temp

post #1 of 5
Thread Starter 
I have an EVGA Z77FTW & 2700K HT/off OC'ed to 4.8GHz and I am currently running Prime95 Small FFTs. EVGA E-LEET shows my CPU temp at 84.0C and my cores are in the 70s at 1.42V (underload) for 15mins.

Should I be worried about the huge variance in temps? Corsair H100i (push pull)?

I had a similar temperature variance when stressing. Just getting it out there.

One is showing the Package Temp, and the other showing per-core. The two will almost never agree, as they measure different areas of the CPU.

I would, however, recommend against using more than one monitoring program at any one time (make sure that there are none in the background by using Task Manager). It can create conflicts and results in nothing reporting the correct temperature.

I always use realtemp for monitoring cpu temps.
post #5 of 5
When people say 'max temp', they are referring to the hottest temp any of the cores ever reached, the peak temp. The reading you are seeing hit 84C is your motherboard's thermal sensor's temp, which isn't too accurate either. This is a well known issue with sb-e, that the cpu temp is always a bit higher than the cores and the core temps is what is important.

Use HWInfo for temp monitoring.You'll get access to WAY more information than hwmonitor, cpu-z, realtemp combined. Realtemp is an awful program. ANyone who still uses realtemp is living in the stoneage, get hwinfo. THere is just so much more you can do with that program, and the guy posts in OCN and regularly updates.

On a side note, a lot of big review websites (cough hardwaresecrets cough) use average temps instead of peak temps, which is why they do horrible heatsink reviews that have very skewed results/ordering.
