One core cooking?

post #1 of 86
Thread Starter 
So yeah, I've had this cpu for like a year now, and it always frustrates me how core 1 always fails and core 2 never does. Finally, I just noticed this. Could it be possible that the thermal paste under the IHS is not spread evenly or something?

I know it's not the cooler since I already tried that...

I've seen this happen a lot, more with Core2Duo systems - the second core always is hotter than the first, but there doesn't seem to be a reason

One of my cores in this opty is allways 5-6c hotter than the other core. It's allways safer to use the hotter of the two temps. I think the main reason this happens is because temp sensors aren't normally 100% accurate, and when you have two that can be off a couple degree's +/- then you get a bigger gap.

Oh, btw I removed my IHS, lapped my cooler. Even before the temps were off so most likely its just off some. My temps are in the mid 40's load with 9x311, 1.375v and my delta on a fan controller turned down the whole way, with the stock cooler I was hitting the mid to high 40's and sometimes bumping into 52c on load.

How did you apply the AS5?

Yes I do. It's normal for dual-core proccies, also depends on stepping.

I think a nekkid chip could help a bit.

Are you having major stability issues? If so, then it may not be down to the temp alone. Well, I say that, assuming those core temps are under full load. 65C is the limit for Athlons, so 56C should be fine.

i think core 2 gets hotter becasue it is the 'top' core when the case is standing upright. if the cooler isnt quite tight enough then the cooler is pulled away from the top slightly under its weight/gravity.

it happened with my Tuniq Tower, Core 2 was 6C warmer and when i tightened it down my temps are now equal on both cores.

the thermal could also be something to do with it, if there is an air pocket above the warmer core it will effect thermal transfer.

try a reseat
