I'm a little surprised that folks in this group haven't suggested liquid
cooling for this modest application. Semiconductor cold plates have been
around for a long time, are economical to use and in my view a much better
solution than forced air cooling. They are compact, quiet, require far less
cabinet space, keep junctions cooler and more stable than air could ever and
enable higher reliability.
Look at Aavid for instance, whose devices I used on many occasions:

If you play your cards right, you can cool the amplifier and the power
supply on a short 4-pass plate. Put the heat somewhere convenient, not in
your shack.
