|Personally, I use the pad for the initial installation. If I find the temps are too high or if for some reason I have to remove the HSF, THEN I switch to paste.|
When you applied the paste, did you use a small dab about the size of a grain of rice & spread it out thinly & evenly over the core? Did you rub a small amount into the bottom of the heatsink, then wipe it off with a lint-free cloth or paper towel?
What about the system temp? Or is that the same as chipset temp? If so, 39C seems a bit high. I just looked at mine & it's 22C with a room temp of 19.5C. How many case cooling fans do you have & how are the arranged?
