The fans are whisper quiet on the K3, if yours aren’t there is
something wrong - possibly as suggested by Stewart below, a wire
touching the hub or the blades, or possibly a missing washer causing
distortion to the fan casing.
Mine just don't come on and I have to use the CONFIG menu entry to get
them to spin so I can check them.

BTW you don't have to wait for the temp to rise to check the fans
'cos there
is a menu entry (Config - KPA3...??) where you can test the 4 speed
settings
of the fans. I always check this after being inside the radio to
make sure I
won't get a fright half way through a sessions when the fans come
on....
