where r u getting your temp's from ?? onboard temp sensor ?? if it was me i would have to verify this temp with a seperate proggy like MBM, or an independant temp sensor, the first thing i would do is get it up and running and when you think it's hot enough, shut that puppy down and stick your hand in there and touch it 🙂 really !!! It sound's like your doing everything right, I had a bad temp probe on an Abit board that would read 50-60, but it ran ok, so i touched it first, ck'd ok....hmmmmmmm, so then i got out a multi meter and it read 38 !!!!! ... verify your temp i guess and go from there 🙂
my 3 cent's 😛
