There are the original fans inside with the yellow sticker. The metal where the fans are mounted on is directly heated from reflector and lamp. In this case, the bearing from the fan is directly heated from the metal, because there is no airflow at all. You can prevent it, if you just put some sheet of fibreglas in between. It will cost barely nothing and is easy to install. So there is no argument not to do it.
I just wanted to protect the gobos from the heat with extra fans. I is not nessesary. Just because I can do it. I got 55€ fans for 9€ each with much better quality than the original ones. They don't mechanically fit into the lamp housing, but they work perfect in the upper housing. The small extra gobo fans are available for 1,50€ each.
