Fair 'nough. I tend to think of the unqualified "convection" as free  
convection, but you're right. In any case, I would think that (on this  
radio) the forced convection for the fan greatly eclipses the free  
convection one would get in a uniform gravity field, making cooling  
requirements a bit of a non-issue in this case.
