Market Price

Cooler Master is a company that needs no introduction to computing enthusiasts. Known primarily for richly-featured aluminum enclosures, Cooler Master has long been a producer of CPU coolers. Performance and style have always been important for Cooler Master; low noise has not been a prominent objective with their products in the past. This helps to explain why SPCR has not reviewed a Cooler Master heatsink before.

The Cooler Master Hyper 6 is a new cross-platform (P4/K8) heatsink promoted as a "high performance and ultra silence" product. Because of its large size and sophistication, the Hyper 6 looks like a good candidate for high cooling performance with a quiet, low-airflow fan.

Hyper 6 is a tall, large, copper heastsink. It makes use of heatpipes, which Cooler Master began incorporating in some of its products last year. The Hyper 6 bears a rough structural similarity to the Heatlane Zen NCU-1000 cooler, but the latter is mostly aluminum and does not have fan mounts, as it is meant to be run fanless. The Hyper 6 is actually one of a more recent wave of tall, large, copper / heatpipe heatsinks with fins parallel to the motherboard, and the fan mounted perpendicular to it. These include:

  • Aerocool Deep Impact DP-102
