CoolerMaster Blue Ice Pro Chipset Cooler Review
 

The thin copper fins are skived, meaning they're actually sliced from the base during the manufacturing process. Because the fins are still attached at the bottom there is better heat transfer than if the fins were soldered. It appears that this heatsink has a missing fin at the far left, there is a ridge on the base as if there was once a fin there, and there is certainly room for one. The fan bracket also appears slightly bent.
