[Elecraft] KPA500 fan noise

[David Orman]

Noiseblocker does too (92x92x25), which I prefer due to color. :) I have no
idea if this is the correct size for the KPA500, I don't have one, and
can't vouch for doing the mod. BlackSilentPro would be the model I've used
in past fan replacements on switches and such. Disclaimer, I have no idea
how this will influence the thermal control of your KPA500. YMMY/mod at
your own risk. Perhaps a call to Elecraft to discuss?
