Got bored, so i knocked up a crude drawing of a cooling/power solution. Its not to accurate scale, but you get the idea. Thoughts?

The fins are far too large, you need to go for surface area instead of mass.

I already have the heatsink and the fins are nowhere near as chunky as my drawing:

I was just illustrating a concept really.
