I have 4 Sonos Amps that are currently stacked on a shelf in a wall-mounted rack, there is no additional airflow currently. When they are stacked in a 2x2 format the bottom ones get quite warm. Currently, not in use I’m measuring the one of the bottom ones at 111F. If I stagger them the temperature seems normal. As they seem to be designed to be stacked, is this an acceptable temperature? During use I assume they will get even hotter, I’ll have to measure.
Otherwise, does anyone have any suggestions? I got the Middle Atlantic 4U Sonos Amp rack as I thought they were actually spaced between the units but they are not. I’m now thinking about getting either the Penn Elcom 2U and using 2 of them to create a gap between the Amps or the Middle Atlantic 2U (they seem basically the same function).
Anyone have this same situation and what did you do?
