CoolerMaster Hyper 6 (KHC-V81-U1) Heatsink Review


Well, this has definitely been an (unpleasant) experience for me. I tried my darnedest to get this heat sink to work, and I badly wanted to like it. No matter what I tried, this heat sink was just plagued with issues. One thing to keep in mind the individual components used in my testing rig. Each system is different (for the most part), and the Hyper6 may work well for you. In fact, I've seen many positive reviews of the Hyper6 on P4 based systems. Just do some research.

Right now, I am skeptical, but with any luck, the problems I’ve had may just be related to a few motherboards. Maybe or maybe not. Matt (LinuXProX) has agreed to have Jason (FanATIc205) do a follow up review on the Hyper6 using his systems. It’ll give the Hyper6 another chance, and maybe some more feedback to CoolerMaster on how to improve on it for the Hyper7 (or whatever the next version is).
The number one thing I’d suggest is to make the dang thing easier to install. It’s been shown over and over again that people don’t like to remove the motherboard to install something, and people don’t like difficult products. It’s not a complicated concept. I had to give this product our “WTF were they thinking?” award.
