lol! yeah, the whistle is pretty distinctive. i think it is annoying, some of you seem to like it. it has to be something sharp protruding into the airflow, inside the plenum (i cant spell if that is wrong), like one of those whistles shaped like a P. i got to thinking of how the noise is occuring after watching "how it's made" at 11 last night, lol! and i want mine to go away!
