Why is there Core temperature difference?

Matrix · 10 Oct 2008 at 16:42

I'm running a Asus P5Q-E with a Q9550 (Arctic Cooling Freezer 7 Pro)i have clocked to 3GHz but when i run OCCT the temps go to :-

CPU1 - 77
CPU2 - 77
CPU3 - 70
CPU4 - 71

And it's the same when the system is on idle

CPU1 - 43
CPU2 - 43
CPU3 - 37
CPU4 - 44

Would it have anything to do with the paste i just put on (Arctic Silver 5 Thermal Compound )

Any info would be great please.

Thanks.

it's normal

Have you got the tjunction set correctly on your temperature monitor software?

Not sure what it should be but a bit of googling should help.

Using core temp and tjunction is set to 0

Its normal due to the IHS being uneven, the cooler mounted unevenly or with uneven pressure or the application of thermal paste

The cores are not all even... each will require a slightly different amount of power at a given frequency and will produce a different amount of heat. Also the temp sensor within each core has an operating tolerance.

The overall effect is that the individual cores operate at similar but different temperatures,

Its nothing to worry about diff temp between 4 core. A little lap will help.
