I can only give you a half a "duh". The preliminary manual supplied with the
amp only gives you the menu description of fan speed and it doesn't really
describe the operation.The paragraph in the online manual labelled "Amplifier
Cooling" is NOT in that preliminary manual. The half a duh is for the first
line of the menu description of "fan speed min".It says the speed varies per
temp but after that sentence there is not much of a description. It then says
greater than zero all the way up to all fans running, leaving you in the dark.
It doesn't explain it like you or Roy explained it.
I really figured it would work like you explained but unless you read the
online manual you are missing the amplifier cooling paragraph. Thanks to you
and Roy for clearing thisup for me.

Per the manual if Fan Speed is set to 0 which is the default, the fans
are not on until needed. The values of 1, 2, 3 etc will cause the fans
to run at the selected minimum speed all of the time, but the fans will
increment to a higher speed as called for by the internal heat sink
temperature. If you use 0 the fans will be off until needed. This
is not related to the fans in the power supply.
