The fans will increase speed when the PA gets hot, but
while I was sitting there at 90 or 100 watts, pressing
the function key to send my call over and over, I
checked the PA temp and watched it rise, so it got me
wondering! 

I'm not at home at the moment, but I think I went to
CONFIG:PA nor    When you turn the VFO B knob you can
step through the fan speeds.  I had to turn the volume
down and you could just barely hear the fan speed come
up.  And you could see the PA temp come down real
fast.

The main reason I was wondering is because on one of
my K2/100's you can definitely tell that the KPA-100
has been run very hot by looking at the solder pads.  

Never did work the XE2 on 6 M CW!
