Scythe's Ashura heatsink ships with a 140mm PWM fan that draws power from a standard 4-pin fan header. The 162mm tall heatsink has six 6mm diameter copper heatpipes rising up through a 121mm tall fin stack. The aluminum fins measure 0.4mm thick and are spaced 2.0mm apart. The bottom-most fin is elevated 41mm above the socket for good motherboard component clearance.

The wire fan clips lack thumb holds so they are less likely to interfere with the back of a videocard; the entire heatsink measures 145mm wide. The heat pipes are soldered to the copper base plate and swaged into the aluminum fins. The outer-most heatpipes are positioned at the center of the CPU base plate and the inner-most heatpipes located at the outside edge of the CPU base plate. This arrangement conducts CPU heat to the region of aluminum fins which receive the highest airflow.

The nickel plated copper base of the Scythe Ashura heatsink measures 43x43mm in size and is between 2-5mm thick. The aluminum support on the top-side of the heatpipes is 9mm thick. A black anodized aluminum shroud hides the caps of the heatpipes for a cleaner profile. Note the small crimp in the leading and trailing edges of each aluminum fin.
