So guys i can't understand is it normal to have different temperatures of the cores ? Or difference coming from somewere such as cooler or something ? My E8400 has 5 - 10C difference @ idle Same situation @ 100% load, most of the time difference is around 5 - 6C... I also saw some other people with same differencies and also saw that on E8500 has no difference... I think about to buy E8500, but to keep this E8400 and i am curious did i had something to do about the temps...
