Nice work, great pricing. We are using a CPU cooler as a heat sink for
some big mosfets.

AlN conducts heat about as well as aluminum alloys.

How flat is it? I.e. how little contact grease can you get away with?

I could measure that, but it is 1 mm thick and obviously polished very
flat. Our stack will be

K199 copper CPU cooler
grease
insulator
grease
four TO247 fets, shiny side up
6-layer PCB
backing plate

The cooler, with springs, screws into the backing plate.

The function is a 200 watt ac/dc programmable dummy load.

I want programmable resistance or current loads, maybe even voltage
(zener) mode, over a wide range of currents and voltages. I have a
cool circuit that can do that.

We will even be able to program waveforms of resistance or current
load!
