Crappermaster has been found to be willfully dishonest in competent technical reviews. I cannot recommend ANY of their products, no matter how good. Fortunately, they have competent competitors. For example, Frostytech found that the Xigmatek Gaia cools better than the Hyper 212+, is within a degree (e.g. the error margin) of the Hyper 212 EVO, and is quieter than either one. I have two of them, one on my IB, and one on my Phenom II. They work well, and I don't hear them.
