Globalwin CAK4-88T From All Angles

The Fan: The seven-bladed fan measures 70mm across and is held in place by four screws to the fan adaptor, and protected by a wire fan grill. The fan adaptor is held in place with its own set of screws. The fan connects via a standard three-pin fan header to the motherboard.

Top: The fan adaptor sits on top of the 60mm x 60mm skived copper heatsink. The heatsink uses one clip on the retention mechanism to hold it in place, in spite of the overall weight of the unit. The clip sits in a 6mm space between the copper fins. The white wires in the right hand side lead to the thermistor which monitors the temperature of the heatsink for motor-RPM control.

Side A: The heatsinks' copper fins are protected by an aluminum shroud with the Globalwin logo stamped on it. The clip requires the use of a flat head screw driver to engage and in general is pretty simplistic. There are no notches to prevent the clip from sliding around on the heatsink which was a little disappointing to see.
Side B:
The skived copper fins are 0.3mm thick and spaced 1mm apart. Fins are 35mm in height. The two holes on the side of the 6mm thick base are for an attachment to make this heatsink P4 compatible... but I don't know if we'd be comfortable using it as such.

Heatsink Base:

The 6mm thick copper base is machined flat, and displays a fairly nice finish both in terms of smoothness, and flatness. The base is undercut 2mm for socket cam arm clearance. Because of the size of the heatsink, one side is notched out a few millimeters for the socket clip to clear.
