and this variation:
take a cube, a very small copper cube over a cpu core and consider distance and surface; a 20mm cube over a 10mm square CPU, you will have a surface 20 times that of core and the longest heat path will be around 20.6mm. I suppose the average heat path will be well below 10mm. This same kind of analysis applies to innovatek shape, (the advantage of 3D heat path being somewhat less in this case but the flow easiness much better).
If i was into try using pelts no doubt i would use 5 pelts over a small copper cube (and if you look at
www.tetech.com it is not too much expensive)
