prelude19: HOLD UP SLOW DOWN! NO GLUE, I repeat NO GLUE!
Just put the glue down and back away!
The heatsinks should just press fit onto the speed controls FET leads(the little metal tabs that are sticking up). Novak makes pretty precise equipment so they should go on with no problem. If they don't, just bend the tabs on the heatsink apart just a little. Just enough so that the heatsink fits over the FET's all snuggly like.
And put that glue away!!!
