getting above 70 degrees C. (158 degrees F.) on itself. You could still run it if you would like having its performance decreased.
I'd like to keep my colleague informed of your words.
You are welcome.
RE 4 Then you need to say that.
Running the motor without proper cooling and ventilation can cause permanent damage to the motor.
RE 5 Then you need to say performs best under 70 degrees or operating above 70 degrees will decrease the performance.
Be specific, and not so wishy-washy about important safety and performance operations.
