I've been using this processor and heat sink along with an 80mm Antec fan for a while with pleasing results, but a few months ago I RMA'd my motherboard so naturally i had to remove the heatsink. Before the change my load temps never went over 50C. Most of the time it was in the mid 40's, but now its gotten pretty strange. The idle temp is usuallyl 33C, sometimes going as low as 28C, but running Winamp or watching a DivX video brings the temp up to 50C pretty quickly. Playing games it will go as high as 60C. I've tried different thermal compounds (i'm using cermaique now) and i've reseated the heatsink a whole bunch of times trying to fix this problem. What could be causing this wacky increase in temperature?
