I recently installed a q9450 and immediately noticed a 15 degree (celcius) variation between 2 cores.
i.e. 30/45/45/30. (core temp/real temp etc.)
I have removed the HSf and reapplied as5 tim and still no difference even after a week or so.
The temps although slightly lower still have a 15 degree variation.
The cpu is a c1 stepping.
Is there any case for concern?
Thanks in advance
