I wonder why smaller devices (including also the smaller fan) with halogen technology or properly heat-producing lamps are barely audible. All the LED projector that I had previously, haten the property to have space for a large fan - larger cooling effect can therefore with less mechanical load - but three or four times as loud as a usual two to three times hotter incandescent Beamer.
The dealers I can only recommend: testing the finished product before you sell it and offers manufacturers the forehead! I am now forced to return the part, because it is in fact waste - where the big picture can do what not even! Too bad!
