Hey guys, I'm new to all this but have a D3 and an L3+ on the way. Can anyone tell me if running these two in a 12'x12' room without ventilation would cause the room to heat up beyond a sustainable temperature? The ambient room temperature is usually around 65 F since it's in the basement.
You absolutely need some airflow. If the are no windows then at least open the door and stick a box fan in there, might be enough. And some free heat for the rest of the house as a bonus.
