[Elecraft] how does the fan work in the KPA100

[Dr. Werner Furlan]

here I am again with my next question. 

I don't understand how the fan should work in my KPA100.
I have set the fan to normal in the K2 PA menue. 
Like this it is off when I switch the amplifier on. 
It goes to fast when I operate for a certain time with high power and the 
heatsink gets hot.
But I did not see a low speed operation of the fan in this mode.

When I switch to low/high, it always runs at low speed and probably switches 
to high when necessary.

Is it correct that there is only one temperature trigger point?
>From reading the bias setting part of the manual, I thought the fan should 
run at low speed also when I switch the PA into high power mode.

Is it correct how it works here?
