Gelid's Antarctica heatsink ships with a 140mm PWM fan that draws power from a standard 4-pin fan header. The 160mm tall heatsink employs five 6mm diameter copper heatpipes which rise up through a 110mm tall aluminum fin stack. The aluminum fins measure 0.4mm thick and are spaced 2.0mm apart. The bottom-most fin is elevated 44mm above the socket for 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 141mm wide. Heat pipes are soldered to the copper base plate and aluminum fins swaged onto the heatpipes. The outer-most heatpipes are generally positioned towards the center of the CPU base plate so the maximum heat is conducted to the region of aluminum fins which receives the highest airflow.

The copper heatspreader at the base of the Gelid Antarctica heatsink measures 35x34mm in size and is between 2.5-5mm thick. The extruded aluminum cap on top is 25mm thick and cross cut with fins. Note the small crimp in the outside edge of each fin.
