The 120mm PWM fan spins at 1000-1500RPM and draws power from a standard 4-pin PWM motherboard fan header. It is backwards compatible with 3-pin connectors. The four 8mm diameter copper heatpipes extend from the base up through all the nickel plated aluminum fins. The cuts in the aluminum base cap are for the CPU mounting clip to lock into. The aluminum fins measure 0.4mm thick and are spaced 2.0mm apart. With the fan removed you can clearly see the bent fin pattern and off-set heatpipe placement.

The Deep Cool IceBlade Pro heatsink stands 155mm tall, the bottom-most fin is 38mm above the CPU socket for clearance of adjacent capacitors, chipset heatsinks, etc. The four copper heat pipes are positioned side to side at the center of the aluminum block where they make direct contact with the processor. The base incorporates a 12mm thick aluminum section to provide support for clamping.

Notice the scalloped pattern on the leading/trailing edge on a portion of the fins? The usable area of the Deep Cool IceBlade Pro's base is 42x43mm. The four 8mm diameter copper heatpipes have been swaged into the aluminum base block and then soldered in place - however it is only intended to distribute clamping support.
