Our country weather is very hot. To save my mining units i switch off 15 minutes for every 2-4 hours.
On that note, do you have some idea how long it takes them to cool to ambient temperature?
For example, are they at ambient after 15 minutes, or is that just a short break? Conversely, are they at ambient after 5 minutes, and you give them 10 extra minutes?
Summer is coming, so I would be interested in your experience.
I was able to measure the heat dissipation of a room by measuring the change in temperature after leaving 120W of lighting on. For that I assumed the temperature outside the room was stable (kept at 20°C by a thermostat in the winter).
If turning the the equipment off for 15 minutes every 3 hours helps, I would just underclock the machine by ~8% It would save on heating/cooling cycles.
