Cooler Master is a major player in the retail CPU cooling and computer case markets. Naturally the company's product roster is extensive and hard to keep track of. One of its newest CPU cooling products is the Hyper N520. Hyper is the name used for a few other cooling products; they appear to be part of a series, somewhat related in style. Most of them are tower designs where the fan blows across the motherboard instead of down.

Heatsinks remain one of the primary noise sources in a PC, as they are usually equipped with a fan, and most fans make audible noise. While CPUs generally run much cooler than they did a few years ago, some still push beyond 100W, and high speed, noisy fans are still basic tools used by heatsink designers. SPCR's general recommendation for silent computing enthusiasts is to use a large heatsink with well spaced fins in conjunction with a large, quiet, slow speed fan which can move as much air as a smaller fan running at higher speed. The Hyper N520 varies a bit from this ideal in that it is equipped with two fans, and at 92mm diameter rather than 120mm, they are not as large as they could be, given the fairly large size of the heatsink. The proof, as always, is in the cooling.

The sample we received came without a retail package, but complete with two mounting systems and two fans. It has a serious appearance.

We bet the packaging is huge, colorful and full of plastics.

CoolerMaster Hyper N520: Specifications
(from the product web page)

The reference to 19 dBA noise level (more correctly, SPL or sound pressure level) without any other qualifications is disappointing. It raises more questions than it answers: Is that with one fan or both? At 1m distance? At 12V/full speed? In an anechoic chamber or a live room?
