With the overclocked CPU, the Freezer Extreme Rev. 2 proves to be more efficient. It produces the same result as the Cooler Master Hyper 212 EVO in its default configuration and outperforms the Enermax ETS-T40, impressive considering the latter two have fans operating at higher RPM. For a small quiet cooler, it proves a good alternative to using high end coolers passively. The NH-C14 is still the superior cooler at the same height being 3.75C cooler.
