6 Heat pipes, full copper, 1x80mm, a recipe for success? The Cooler Master does impress when you get the heavy box stuffed into your hands. The packaging is simply stunning, a lot of attention went into it and having to tear it apart to get to the goodies inside can be hard.


Nice packaging




all the goodies included for installation

The Hyper6 has room at each side to fit an 80mm fan, although by the looks of the included mounting material you're supposed to have only one installed. The Cooler Master fan's speed can be adjusted from 1800 to 3000rpm; a useful front bay/rear PCI bracket is included for mounting the little rheostat. To obtain good contact between the heatsink's base and your CPU they also included a tube of thermal paste, infinitely better then those pads.

The included fan is quite noisy at the highest speed setting but moves a lot of air so that can be forgiven. But when turning down the rheobus dial to the lowest setting we hear an unpleasant sound coming from the HSF setup, the fan vibrates at lower RPM and the housing to which it is attached on the Hyper6 starts to make a ringing noise which stops as soon as you lay your hand on the top. Placing rubbers at the top of the heat pipes between fan mounting bracket should resolve this issue. The noise of the Cooler Master at low speed with the ringing sound was almost as taxing as using the Tornado fan at full speed, not a good sign.


The included fan takes power straight from the PSU but also included an RPM monitor to plug into the fan header on the motherboard

The base is smooth as can get, lapping this heatsink will only damage it I think, and the finishing is the best I've ever seen.




The fins of the heatsinks have serrated edges to increase the cooling surface and improve cooling efficiency
