The last step is optional, which I personally don't think should be. You can choose to install a fan or keep it passive. I chose the active cooling because I'll be overclocking.

The fan is adjustable, you just have to assemble the dial with the included bracket. There is also an option to install it into a 3.5" bracket to control it in the front bezel. Both methods are included in the package.

Here is the heatsink after everything has been re-installed and tucked away.

We tested the unit on our rig that consists of:

• Abit IC7 Motherboard, latest BIOS
• Intel P4 2.4C @ 3.0Ghz
• BuffaloTech 1GB DDR
• MSI FX5900 Ultra 256MB
• Maxtor 80GB 7200RPM HD

So how does it perform:

CM Hyper 6	Fan Speed Low		Fan Speed High
Ambient Temp. ~ 27C	Idle	Full Load	Idle	Full Load
	44.0C	47.1C	41.2C	45.5C

Not bad at all, it does about a degree better than our previous favorite from Scythe.

However, I would only considered using this heatsink if your rig is not moved often. The weight of the heatsink may just cause damage to the motherboard if the case is jolted or dropped. Definitely not a LAN friendly unit.

The installation process should be easy for the experienced user, slightly difficult for the novice. The only major gripe I have is the instructions. They need to be redone if CoolerMaster expects the normal joe to install this thing. The pictures and fonts are WAY too small to read.

Thanks to Jab-Tech for sending over this monster unit.
