The Heatsink Fan:
The Scythe Ninja Mini's 80x80x25mm fan spins at a moderate 2300RPM, producing roughly 42 dBA according to Frostytech's real world sound measurements. The fan draws power from a standard 3-pin fan headers. Only 80mm fans may be used on the Ninja Mini owing to its small size.

Heatsink Frame
The sixteen aluminum fins of the Ninja Mini heatsink have a cross profile, and are versatile enough that the fan can be mounted to any side you choose. Two springy wire clips make that happen, and they are sized for 80mm fans if you decided to adopt something other than the fan Scythe ship with this heatsink. At the center is a hole running through the heatsink 21.5mm in diameter.

Heatsink Side B:
The Scythe Ninja Mini comes with three different mounting brackets for various Intel and AMD CPU sockets. The Intel LGA775 clip uses standard Intel push-to-click plastic retention feet, the 478 model the existing tabs. The AMD version locks onto the central lug of the heatsink retention frame on either AM2+/939 models. Aluminum fins are 0.36mm thick, but fin spacing is a littler larger than usual; 3.75mm. That makes the Ninja Mini well suited to slower moving airflow. At the bottom you can see the edge of the its copper base, which is ~7.25mm thick. The base is soldered to each of the nine copper heatpipes.

Heatsink Base:
The base of the Scythe Ninja Mini heatsink has a machined, heavily chrome plated and polished finish which is mostly flat, but not perfectly so. The copper base plate measures 38x38mm in size - just perfect for an AMD Athlon64 heatspreader. Surface roughness is equivalent to ~8 microinches, which is considered excellent. The nine 6mm diameter copper heatpipes are soldered to the copper base. Compression joints are used with the heatpipes and the aluminum fins. The CPU socket mounting brackets attach to the extruded aluminum portion of the Ninja Mini's base with four screws.
