Taisol CEP409151A Pentium 4 Heatsink Review
Taisol CEP409151A Pentium 4 Heatsink Review
Abstract: With a difference as close as this to the stock Intel we can pretty much say that the two heatsinks are on par.

CEP409151A From All Angles

The Fan:

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.

Side A: From the side you can sort of see how complex looking the heatsink is. The metal tabs on either side of the fan which come down clip onto small barbs from the metal support posts and then lock into place. The fan is attached to these metal arms and the entire structure rests freely on top of the fins. There is not texturing on the fins, either inside or on the outside of the heatsink.
Side B:
The base of the aluminum extrusion is 8mm thick and tapers off a bit to either side. The fins are spaced 1.5mm apart at the base and just over 2mm at the top. Each of the 28mm high fins is roughly 1.25-0.75mm thick, tapering up towards the top.

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.
