Well, unfortunately there isn’t any way around the temperature limitations…the ranges are set to prolong tube life. (Operating temperature is a concern with all lasers.) The Basic and Plus units are air cooled, they can heat up from seven to twelve degrees above ambient temperature when they run for long periods (I think I saw that somewhere here on the forum, don’t quote me on it) . But if it’s true, we need to get the air going into the intake cooled off.
There are some standard suggestions below for ways to cool the environment off, and there are a lot more creative alternatives in the Beyond the Manual section that have let people run them in some pretty extreme conditions.
Recent changes made by the team will let you try running the fan without printing to cool things off:
