Can i please have an opinion from you guys:

Q9450 @3.2GHz 1.264V with a lapped TRUE+Scythe SFF21F(1600rpm)+AS5 on it.
Why is there a so big difference between the cores? I checked the cpu and its absolutely straight. Also i did the washer mod on the TRUE and it doesnt move one mm now. Is the mobo temp sensing wrong? Those temps are at idle but with a rather high ambient temp, around 30C or more.
