I really want to cool my cpu down but i'm wondering whats the best way to do it. I've tried reseating the heatsink and that lowered temps but not the load ones. (Q6600 B3 stock 75) Due to it being a dell i cant install a new heatsink (i hate dells now. Wasn't so into pc's when i brough it) but i have noticed that the heatsink seems to be passively cooled. The only fan is at the front of the pc is about 5cm away blowing air onto it. Does anyone know if i can install a fan onto the Dell E520 heatsink (i even thought about sticky tape ) Also if i was to add two exhaust fans could i see a difference or not.
