redsectora , my amps are in free space next to each speaker so can't improve on ventilation. running a fan is not an option. Years ago (like 20) I visited a house where the owner had periodically spray some aerosol on his Mark Levinson's to stop them overheating
I don't want to go down that path!!
It is summer in Australia, but they worked flawlessly through 2 previous summers so I doubt it is ambient room temperature...and it is one amp that heats up very quickly.
