Do you think you can do better then this? Or need to? Now if its an exercise in learning and just the fun of doing it, well that's a great reason. But I would think the tip temp will cool that much if you just blow on the tip. but to raise it will take full power for a few seconds to get it back, then it will overshoot. Just my HO.
Just so we are all playing on the same field . . . are we talking degrees C or degrees F ? I am guessing Centigrade so that's more like 13 or 14 Fahrenheit.
