Cooler Master Hyper 412S / Hyper 412 Slim review: finally a Mugen 2 killer?

Test results cooling performance high-speed

With fans on high, the cooling performance of the Hyper 412S is a bit disappointing, even if we understand the reason for this when we look at the noise production test. The Slim version with its two fans performed quite well compared to other affordable CPU coolers, and lands Cooler Master in the top 5.
