The XtremeGear HP-1216B heatsink utilizes a dimpled surface texture on its raw aluminum fins as well, and quite amazingly retails for $29! Standing 153mm tall, the HP-1216B heatsink is equipped with a single no-name 120mm fan that rotates at 2000-1000RPM and is illuminated by four blue LEDs. At full speed it's moderately audible, and at the slowest speed you'll get good performance a nearly silent levels.
