John,
The KPA1500 fans are relatively quiet - they move a lot of air at lower
fan speeds.
However, the power supply fans put up a bit of noise, so shipment was
delayed while the fans for the power supply were reworked with larger
fans to keep it quiet.
I have only heard the fans while visiting the Elecraft lab, so take the
information provided by K6XI's eham review as a better authority than my
comments.

How about in a RTTY contest where most SS amps need super high fan speeds to
keep cool?
