Necessary? No. 

A good idea? _VERY_ much so. Putting a fan in to move air through the
radio will do wonders for extending its MTBF. Hot components change 
value faster, and they die faster.

How? I don't have a CY-979 to play with, and don't know where the 
cooling apertures -- if any -- are. But I'd give serious thought to
putting a fan under the bottom, pushing air in, and one on the top, 
pulling air out, even if I had to make holes to do it.
