[Elecraft] KPA500 Internal Clicking Sound

[Michael Cozzi]

     Dale,

     Was there a temperature improvement by using the grease?

     I've seen 7c+ reductions by using Arctic silver type compound on 
processors instead of the stock melty pads sometimes provided.

I fixed mine by taking the heatsink off and using heatsink compound on it to the mating surface then I used locking washers under the machine screws and tightened it down, be careful not to over toque.  The clicking is caused by the heatsink expanding and contracting.
