Hi David, that sounds very intersting and that was my thought from the begining , the more silent a machine is the more effective it really is, coul you give more info about that fan?
Kalle heres a story for you airplane heads from an electrical engineer. i used to work for Black & Decker years ago. and once we did an experiment with a certain tool for marketing. one tool had the normal not so efficient fan in it, and the other had a super quiet high efficiency fan in it that actually allowed about 25% more runtime off the battery, including a bit more power. we took them out into the field for user comparison. ~every~ ~single~ ~person~ we did the comparison with thought the louder, less efficient tool was more powerful BECAUSE OF THE NOISE. even though they were dead wrong, thats what they thought, and thats how they bought their tools. my 2 cents[/quote]
