My experience with the Pegasus is that in PSK - a very efficient mode -
the heatsink stays acceptably cool. However in RTTY where I have
to run it full blast, it gets HOT. I also use an amp in RTTY mode, and
I tripped its overtemp out. Thus I had to add a second fan to the
amp.
As others suggested, I just set the fan on the table adjacent to where
I wanted the cooling. I run it off the same power supply as the rigs, so
it always goes on when the rigs do. But I only need it in RTTY.
