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?
