MF014021 From All Angles

The heatsink we tested came with a Everflow fan attached. The 10mm thick fan is low-profile and draws a scant 0.25A. Because of the small size, the fan is very quiet in operation, and power can be drawn from the motherboard via a standard three-pin header. There are about 4mm of clearance below the fan, and above the square tips of the fins for improved airflow into the fins.

Top: The fins are spaced about 1mm apart and the tips are squared off. Thus the surface area of this heatsink is pretty large. All of the aluminum fins have been plated with nickel to facilitate joining them with the copper base.

Heatsink Base:

The MF014021 base has been machined flat and smooth, then plated with nickel for a very good overall finish. A thermal pad comes standard, but it can be removed if you wish to use arctic silver or another type of thermal interface. The base finish on this particular heatsink tested with an engineers straight edge and proved itself to be very flat as well. Some very minor imperfections meant it isn't perfectly flat, but they will have no significant bearing on how the heatsink mounts on a silicon processor core.
