CPU temp difference- CoreTemp, Ntune or BIOS?

[king144]

Quick question, Im getting different temps from my [email protected],volts1.4, Ntune and my BIOS says im idle at 35-38c and always has but i read that coretemp is the most accurate so i got the latest version and took a look and it reads 25-30c, i know its not hugely important but its a fairly big difference and im wondering which one is most accurate. Im instaling an opty170 this week and be nice to know which is best. come on coretemp

Thanks for the reply but ive got my dual-core opty 170 in now and it seems to have evened out, theres still a slight difference but very small. Im at 2.9gig and at idle with core temp core 0= 31-34 and core 1= 29-31. Im very happy, ive only had it in an hour or so and i havent even had to raise the voltage. I expect the temps to drop a little more when the AS5 has settled.
