[Elecraft] KPA-500 fan noise

[Fred Townsend]

I would hate to think what would happen if a water line breaks. Why not duct the air from a portable AC unit to the KPA-500. Then when the ducting breaks you won't have water all over the place... just cool air.
Seriously folks, any chance the exhaust air from the KPA is being fed back into the air intake for the KPA? That will heat things up in a hurry. Maybe outside air (depending where you live) ducted to the KPA would keep things cooler. Failing that just empty the contents of the beverage cooler into your stomach and after a while the whole room will be spinning. The fans will be still running but you won't notice.
