I have never been on FT8 mode and I rarely use my KPA500 so take this with
a grain of salt. I would set the fan to a speed that provides some air
flow without being annoying. Perhaps speed 2 or 3, if I recall correctly.
This should at least delay it turning on the noisier higher speed speed
fan and may minimize some of the cool down clicking.

In running my KPA500 on FT-8 mode at about 400 watts output, what is the
recommended setting for Fan CTL? I usually keep it in NORmal but have
tried other settings. I watch the TEMP and see that it gets above
65ºC. The fan speed increments up and down as the temperature changes
accordingly. All appears norms. But, do you find setting the Fan CTL
to some value is more efficient in regard to cooling?
Thanks in advance for your inputs.
