I have an AMD Phenom II X4 970BE CPU currently running at 3.8GHZ, but to make up for the loss of performance due to age I would like to go a little further, possibly 4GHZ+.
My Arctic Freezer Pro 7 Rev. 2 is good at keeping temps low on stock clocks, but I don't want the temps to go any higher. Considering that I would like to possibly reach for about 4.2GHZ, what will the following two things actually do?
A) I have a CM Storm Scout case and I am about to fit two red LED 120mm fans on the window, blowing air at my GPU and CPU. These will both be pumping about 50CFM of air, will that help my CPU temps decrease, and if so, by how much?
B) The Arctic is a £15 cooler that outperforms many £20-£25 coolers. But, for serious overclocking, should I consider a different cooler like the Coolermaster Hyper 412S. It has favourable reviews but how much of a difference will I see going from my Arctic?
