Deepcool Ice Matrix 400
 

The Deepcool Ice Matrix 400 is a solid contender compared to other heatsinks in its price range. Under stock situations, it closes in on the Noctua NH-D14 and the recently tested Zalman CNPS9900, which are currently at the top of the market. However, when having to deal with even a mild overclock, it cannot compensate as easily for this extra heat output as the higher end heatsinks.
