As with other Zalman products I've reviewed, the CNPS10X Flex is a well-engineered product that does what it should do and does it very well. The build quality is great and it performs admirably. Installation was very simple thanks to the included manual. The heatsink is also compatible with many different sockets and it even supports the latest Intel socket 1156. Furthermore, the ability to use 120mm fans of your choice is a plus.
