I have the same X-3 as you and have wondered about adding a fan. Should be easy to add a "muffin" fan to blow across the heat sink. I'll get around to it one of these days.
I got tired of cranking the head up and added a 40-50 lb counterweight/compound pulley arrangement. The head goes up & down very smooth & easy now. Probably works better than the gas strut.
Gentle enough for yer?
