The 92mm non-PWM fan spins at 2200-800RPM and draws power from a standard 3-pin motherboard fan header. Just two 6mm diameter copper heatpipes rise up through bare aluminum fins which have a dimpled surface texture. Each aluminum fin measures 0.4mm thick and is spaced 1.7mm apart. The surface texturing on each fin consists of a very small dimple popping out on both sides of the metal.

The SilenX EFZ-92HA3 heatsink stands 125mm tall, the bottom-most fin being 33mm above the CPU socket. The two heatpipes are positioned side to side where they make direct contact with the processor. The base incorporates a 10mm thick extruded aluminum section to provide support for clamping, with 10mm high aluminum fins for a little extra cooling surface area.

Looking at the top of the SilenX EFZ-92HA3 heatsink we can see dimpled fin texture easily. The base of the heatsink measures 35x44mm in area. The two exposed copper heatpipes are centrally located both at the base and where passing through the 53mm-wide aluminum fin stack.
