Okay i recently got the Cooler Master Seidon 120v V.2, and my CPU is a AMD X4 860K Overclocked to 4.00Ghz. My Case only has 2 fans at the front. And of course the fan attached to the radiator at the back. CPUID HWMonitor PRO says my CPU is staying into the 60-70s Area. I installed it correctly. Does the thermal paste need to cover the whole cpu? Shall i get a refund and get the Hyper Evo 212?
