[Elecraft] Noctua fan for the KPA500

[Dr John H Farmer]

Good question! I had a look, but couldn't find a Noctua fan with the same specs as the stock Sunon which came with my KPA500. I did find that the fan noise on the KPA500 was reduced by mounting it on a silicone gasket and I'm happy with the improvement it made, so will leave it at that. Besides, there's much greater airflow through the KPA500 and I never expected it to be quiet, I just wanted to reduce the mechanical element to the noise. The gasket approach didn't help at all with the K3 fan noise, FWIW. 

If anyone explores the KPA500 fan situation further, I'd love to hear. 

Cheers, John
