I have a i7 920 on a P6T deluxe motherboard. When I load setup defaults in the bios the idle temp is around 50c and 80 under load. I have it clocked at 3.9 and the idle temp is the same but under load its 89c. I replaced the stock heatsink with an artic cooler freezer 7. The temps did not chance at all. I have reseated and reapplied thermal paste multiple times and checked for dust. I cant seem to find out why this chip is burning so hot. Is there a heatsink that will actually get the temperature's down or should I just invest in a new chip.
