Ok so I upgraded my CPU the other day and the temps reach 80 almost 90 when playing bf3. My temps would never go above 60 with my old CPU, which was a athlon 64 x2 3800+. My new processor is a athlon 64 x2 5600+. I use arctic silver 5 thermal compound. Both of the CPUS TDP are 65w but 5600+ is 900mhz faster. I use the stock cooler that came with my computer. Please help me!
