Not sure what you are asking.... I run vintage tube amps with NOS Mullard tubes (i.e. $120 per tube x8) in an enclosed cabinet (some of the time) with auxiliary fans that kick in around 90 degrees without any problem.... The fans on my son's Xbox and PS3 work fine but are just too loud for my taste. Texas in the summer w/o ac might be a problem.... so what's you're concern?
If the cabinet is vented and the room temp is ok, you should be fine...
