- The room is usually 70-72F [21-22C] through the day, since it is our basement.
- When I open the window, and pull the air in via the fans, I get that down to around 66-68F [19-20C]
At the temps you mention, I would use these on low for sure, and only mix as needed. Probably even cycle them on/off through a workout with that cool of a base temp.
