Coolermaster Hyper6:

When Coolermaster uncovered their new high end heatsink at Cebit 2004 it made quite an impact. Weighing in close to 1kg it almost triples Intel maximum weight specs for the P4 heatsinks. 1kg of copper, 3 heatpipes it sounds promising and extreme!

Specifications:

This heatsink can be installed on:



* 3 seperate copper heatpipes joined at the base
* 80mm fan support (a second fan be mounted if you find the correct mounting screws)
* 80mm fan included with rheobus
* 990gr without fan

Construction:

The Hyper6 has an outstanding finish, the base is extremely smooth, the overall construction is well thought out, the different platters have see-saw dents to increase cooling surface.


Installation:

Installation is a breeze as it uses Intel’s default retention bracket. The clips slide over the lips with great ease. The heatsink sits quite high and towers over your motherboard, installation of the Coolink 80mm fan went without issue.

Problems and issues:

Although Coolermaster came close to perfection with this heatsink, they are a few bad points, the included “universal” mounting bracket which is required for installation on A64 platforms does not fit my Asus P4C800, not a big problem but worth mentioning. The fan bracket sits a trifle loose and with the included 80mm Coolermaster fan it will vibrate and create quite some noise, even at low fan speed. Due to its high weight I strongly recommend removing the heatsink when transporting your PC, the damage 1kg of loose metal can do inside your PC is not to be underestimated. Coolermaster is using a custom Fan design which requires shorter screws for mounting, swapping the fan with one of your own is not plug and play as you have to have the correct screws.

Performance:



The default Coolermaster fan spins slower then the Coolink at high speed, but faster at low speed, this can be seen in the graph above. The Hyper6 delivers stunning performance even with the fans running at their slowest setting.
