I recently installed my Antec 620, I have it set up push/pull and my CPU temps I feel are way to high. It idles around 33-40C but gaming/CPU intensive things it may heat up to 50-55. I have it Oced to 4.5 Gigs would that be why my idle temps are so high? The only other things I can think of is to try reseating the heatsink, or rotating the radiator.....I installed it with the tubes at the top it helped with the case air flow/temps. But this should not be the cause. Any help would be greatly appreciated. Thankyou
