 Not really since the heat exchanger is in a different location. Usually outside. Liquid is more efficient in removing heat from the heat sink.  We have 7 100KW liquid cooled solid state TV transmitters here in NYC atop WTC1. They are all in the same room and the room is nearly dead quiet.

Until someone moves to liquid cooling like TV transmitters and some gamers. :-)

If you have a SS amp it’s going to have to move air.
