Cooler Master N600 Review @ OCC
 

The CPU and GPU idle temps were as expected, nothing remarkable. But under a load, we see the CPU temps on the N600 well below the other cases. I let things cool down, and ran the tests again and got the same results. So, what gives the N600 such an advantage? Normally the CPU cooler has to draw air in from inside the case - air that has already taken on heat from the internal components (motherboard, RAM, GPU, HDD, PSU, etc.). Well, since I am using the Corsair H70 CPU cooler mounted at the rear (in a push / pull configuration), and the top of the case is essentially open and very close to the intake of the H70, it appears that a fresh supply of ambient air was available to the H70, and I suspect that this kept the CPU temps down.
