The 92mm PWM fan spins at 1200-2000RPM and draws power from a standard 4-pin PWM motherboard fan header. It's backwards compatible with 3-pin connectors. The two 6mm diameter copper heatpipes are soldered to the nickel plated aluminum fins and copper base plate. The aluminum fins measure 0.30mm thick and are spaced 1.5mm apart. With the fan removed you can see how simple a heatsink the Freezer 11 LP really is. The heatpipes extend and additional 16mm and 20mm beyond the fin stack.

The entire heatsink is 53mm high. Two 6mm diameter heatpipes conduct heat from a 2-5mm thick copper pad to the outer portion of the aluminum fins. The aluminum fins range from 100mm wide at the top to ~70mm wide at the mid-point of the Freezer 11 LP heatsink. From top to bottom the aluminum fins are 32mm deep.

The usable area of the Freezer 11 LP's base is 32x32mm. Each 6mm diameter copper heatpipe is soldered to the copper base block and to the bottom of the nickel plated aluminum fins. A patch of Arctic MX-2 thermal compound is pre-applied to the base of the heatsink. Note how the flat ridge along the sides of the heatpipes is angled by about 20 degrees downward to better deflect hot exhaust air outwards.
