CEP409151A From All Angles

The fan is generic and draws 0.24A, rotating at about 3800RPM. At 70mm wide and just over 10mm thick it is one of the larger form-factor slim line fans we have seen recently. The sound level is not too loud, but noticeable. The fan draws its power via a three-pin motherboard fan header which supports RPM monitoring.

Top: The small square bit of metal at the center of the heatsink fins is there to serve as a support for an under the fan cam. When the arm is locked down, the cam forces the heatsink body down with even pressure over the core of the processor. The aluminum fins of the extrusion are not cross cut for added surface area or exhaust reasons which is a bit interesting.

Heatsink Base:

A small patch of pre-applied white silicon compound on a sanded base is alright for Pentium 4 processors with their metal heatspreaders as flatness is at least very good. Surface smoothness is satisfactory at best. Note the four mounting holes for use with Taisol's custom HSRM.
