Molex 371660002 U. 371610002: Little Brother
In contrast to the large Molex cooler, the other two we tested weren't quite as efficient. Their cooling performance was considerably weaker. The cooler with the green CPU clamp (Molex 371660002) has a green, thermally conductive fillet on the CPU contact surface, while the other cooler has a small, flexible metal plate on the contact surface. On the upside, the operating noise level is minimal.
