Should my temps be different on the cores of a dual core

[dario03]

I put a CoolerMaster Hyper Tx2 hsf on my amdx2 3800 and it has helped with the cooling. Only problem is it help one core more than the other. I use to have the same temps on the cores or with 1 degree. Now with my overclock I'm getting ~44* on core0 and ~40* on core1 according to speedfan and ~47*,~41* according to coretemp. I took the hsf off and checked the as5, it looks like it is spread good.

So which program is more accurate?

Should my temps be different?

On a skt939 x2 do the cores sit above each other or side by side?

Any other reasons this would be happening?

the temps will vary, yes.

I get as much as 10C difference between cores on my quad. Its all about how much usage is going on and how good of contact your heatsink has to each core.

This is under 100% load on both cores. I was thinking the weight of the heatsink might of pulled it off one of the cores a bit. Laying the computer down helped a little, so that might of been it.

The extra weight of the heatsink is going to cause it to make better contact at certain points. Playing WoW keeps my core 3 at 90+ usage while core 0 is almost nothing and core 0 still runs hotter than core 3.
