[damien c]

i would take a guess and say the 90c is the northbridge and that the 65c is the southbridge, and i would check the bios for the temps and use everest as zingle has suggested i don't use anything else and it works fine for me.

what motherboard and chip have you got if it is a motherboard with a nvidia chipset then i would be 100% sure, about the guess above as they do run hot but not that hot intel chipsets run allot cooler also have you overclocked the cpu?

i would also check that fans are running and free from crud also if possible try to reapply the heat compound like artic silver that might help.
