"If you are looking for a heatsink to help push that processor overclock a little farther, than look elsewhere, that is not the aim of the CNPS8700. But if you are looking for a cooler to keep your home theater pc cool without also being heard, the 8700 is just what you are looking for. Zalman has once again released a solid product that retains their silent computing legacy. Whether or not you choose to use the included Fan Mate 2, the 8700 will satisfy any silent computing application. While I don't have any numbers it's also worth noting that the design allows for additional airflow over neighboring motherboard components, an added bonus many heatsinks do not give."
