The 120mm PWM fan spins at 2200-1000RPM and draws power from a standard 4-pin PWM motherboard fan header. It is backwards compatible with 3-pin connectors. Each of the three copper heatpipes are 8mm in diameter and extend from the base up to the top of the 112mm tall fin stack. The aluminum fins measure 0.3mm thick and are spaced 2.0mm apart.

The Silverstone Argon AR01 heatsink stands 159mm tall, with the bottom fin elevated 37mm above the CPU socket for clearance. Heat pipes are spaced 3mm apart at the base plate and where they intersect the aluminum cooling fins. The base incorporates an 11mm thick aluminum section to provide support for clamping. Notice how the white rubber fan mounts attach to the sides of the aluminum fin stack.

The functional size of the exposed heatpipe base on the Argon AR01 heatsink is 35x40mm. Looking from the top down we can see a bit of edge treatment going on and some 'tire tracks' stamped lightly into the surface of the 120x40mm plain aluminum fins. The plenum behind the fan is 5mm. Heatpipes are positioned in the path of highest airflow.
