920 D0 Temps vs C0 Temps - consistency?

[krazynutz]

I have two PC's. One has a 920 D0 and the other a 920 C0. Both have Xigmatek HDT-1283's on them with the same compound.

Regardless of idle/load, my C0 temps seem to be much more consistent than the D0 temps.

C0 temps: 39-38-39-38/72-70-71-70 - 3.8Ghz @ 1.275v - Asus Board

D0 temps: 38-37-33-32/68-67-62-61 - 4.0Ghz @ 1.25v - EVGA Board

As you can see, the C0 temps are very consistent. The D0 temps kind of decline through the cores. Usually, two cores are 4-6 degrees higher than the other two. I've remounted and reapplied compound three times on the D0 machine and it doesn't change a thing. The only thing that stays the same is the difference in temps between the same cores. I've even rotated the cooler 90 degrees and the temps stay the same.

Is this typical of D0 920's? Do I need to calibrate anything? Do EVGA boards have an issue reading temps properly?

Its normal to have temp differences like that. I have a Ci7 920 D0 and my idle @ 4ghz is 38, 36, 35, 32. Although under load it evens out alittle to 69 68 68 66

Using a lapped TRUE with push - pull fan config 1.25V like yourself.

Its nothing to worry about, infact your temps are really good.

I agree with omgitzfatal. Those temps are good and the variance is not an issue.

Okay thanks. So that's typical for the D0's then? Does anyone have any C0 or D0 temps they'd like to share?

If I switch CPU's on the boards, I wonder if I'll get different results depending on the board. Anyone know if that's a possibility?
