Initial CAD & Costing

The cooler only has 7 distinct parts, 6 of which are custom manufactured.  The five most critical components then are the mounting frame, fan blade, heatsink, locking plug and locking pin.  To analyze these components, I recreated each of them in CAD as shown below.

Costing

With each of the critical components recreated digitally, I was able to run costing analysis simulations on these CAD models using the aPriori costing software.  The results are shown in the table below.

​

These costs are compared to estimated costs of similar parts found on McMaster-Carr.  Due to the fact that most of these parts are custom made and very specific to this application, McMaster does not carry similar parts to many of these.

 

A single whole fan was used to compare to the collection of fan parts found as a whole and a generic finned heatsink was found to compare with the specifically-shaped one on the Intel stock cooler.  Also, nothing similar to the locking plug and pin was found on McMaster, so a similarly-sized and featured plastic screw anchor was used for comparison.

Unfortunately I was unable to produce a properly simulated costing of the heatsink with aPriori due to its complex geometry.  These heatsinks are typically made either an extrusion process, or with a specialized forming machine which slices and folds each fin up from a solid block of aluminum.

​

As neither of these manufacturing methods is available in aPriori and I was unable to operate the manual costing setup, the closest option available of "cast machining" produced a fully-burdened cost estimate of $65,342 per part.

​

The above figure of $1.11 is a combination of the raw material cost (about $0.27 per part) with an added factor, and an aPriori simulation of making the part via die casting.
