Designed for mini-ITX motherboards and small HTPC enclosures, this 120/80mm low-profile cooler has four heatpipes, and measures only 63mm in height in single fan mode (pictured below).

 Think of this as a smaller version of the 140mm C-type cooler.

The 120/80mm low-profile cooler accepts one 120mm on top, and one 80mm underneath.

Dual fan mode will give maximum performance, while a single 120mm would give more clearance, and a single 80mm for minimum height.
