I have just finished my new build and I have overclocked my q6600 to 3.0ghz. At idle the temps are 40-44c and at full load they hit around 70c. I am using an arctic freezer pro 7 and antec 900 with all fans on high and I'm not sure if these temps are too high. I heard that once the thermal paste on the arctic freezer pro 7 sets the cooling is better, is this true?
