Zalman CNPS14X Lower Noise Heatsink Review
 

"As a single fan heatsink the Zalman CNPS14X performs very well, but the higher the heat load the better the advantage there is to be gained from adding two more fans... so... Zalman include extra fan brackets for users who want to add their own 140mm fans. ;) Since this is a novel approach, Frostytech is going to test Zalman's CNPS14X heatsink in its single fan configuration (stock) and also in a three fan configuration."
