HI, My new pc is running at about 55 degrees idle and after a quick game of far cry about 65 degrees. I'm just using the standard heatsink that came with my xp 2600 which said it had a thermal sticker on the bottom so i thought there wouldnt be any need for thermal paste, do i need some?Also i have an 80mm case fan next to the cpu. Should i have it blowing air into the case or taking air out of the case? Thanks,John.
