I am tying to cool my 2600K temp better than 34c idle and 66c for load using Prime95. I have the fans on either side of the radiator blowing air outward on the back of my case. Here is what I got, MSI P67 G80 motherboard, 2600k clocked using Genie at 4.2ghz. The ambient temp is around 72 degrees Fahrenheit. The case is cool but I can't get my temp lower. I tried Diamond IC 7 compound as well as the thermal compound that came with the H80. Both seem to be about the same temp, maybe lower with the Diamond compound. Could it be the core voltage using overclock genie at 1.35? I'm seeing people with lower temps using this cooler. Could it be my Dell 730x case? It gets plenty of ventilation and air circulation.
