[Elecraft] KPA-500 fan noise

[Harry Yingst via Elecraft]

You could always try replacing the fan with a quieter fan.
I do not have the KPA500 (Yet) but I did replace both the Fans on The K3 with Fans from Noctua.
They are a lot quieter, The only downside is the color of the Fans, but not a big deal since they are in the back

Thanks to all who replied.  If I did not have to cut a hole in the sheet 
rock, I would install a dryer vent!! I think I will try setting the fan 
to a minimum speed as suggested and see how that works out keeping the 
air moving all the time.
