The two 120mm fans each spin at 1000RPM and are arranged in a push-pull configuration. Each fan draws power from a separate 3-pin motherboard fan header which can be problematic for motherboards without extra fan power headers. The four 8mm diameter copper heatpipes extend from the base up through the fins. Each aluminum fin measures 0.2mm thick and is spaced 2.0mm from the next.

Evercool's Transformer 4 HPJ-12025 heatsink stands 159mm tall, with the bottom-most fins elevated 49mm above the CPU for clearance. The chrome plated 120mm fans extend out about the same distance from the heatpipes on either side . Four copper heat pipes are grouped side-by-side in a straight row, and make direct contact with the processor IHS. The base incorporates a 13mm thick aluminum block to provide support for clamping.

The usable area of the Evercool Transformer 4 HPJ-12025's base is 49 x 43mm in size. Looking from the top down reveals a 12mm plenum created by the raised edge of the aluminum fins. Note the three 1.75mm tabs of aluminum separating each of the copper heatpipes on the base.
