No problems in case of fan usage, of course.
Like well known USRP's.
And I think, that 40x40mm fan can cooling two PA's around 0.5-1W each.
But do not ask "whats up?" if fan stopped ;)

Do you think those cases can't sustain UmTRXv2+UmSEL heat dissipation
if supplied with a fan? Remember we're talking about a lab enclosure
without any additional power amplification.
