Skip the Coolermaster CPU Cooler. First, you're unlikely to need it unless you feel like running a high overclock (there should be no need), and second, Coolermaster is a dishonest company (fact) and does not deserve business (opinion). If you really want a CPU cooler anyway, check out the Xigmatek Gaia, also 120mm and configured similarly. Mine keeps my 3.8GHz 970BE idling around 30C.
Ew... I had the Xigmatek Gaia and it almost fried my motherboard and CPU, that is a fan I wouldn't recommend. Sure it's easier to install than the Cooler Master is but the Xigmatek fan isn't really worth it IMO.
