EcoPlus 6" Whining and Whaling! WTF?!?

Any ones Eco Plus fans whine and whale? Mines brand new got it out of the box hooked it up, way too much power, so I got a varible rotary knob installed on the cord. You have to sit there a mess with the knob for like ten min to get the loud whaling and whining kept to a min.

This sucks, I bought this fan in order to move air fast and quite. Anyone else had these problems?

Oh yea its hooked to a 1khps cool tube.

Anyone recommend a brand of fans thats super quite? I've been looking at ellicent or whatever.

Thanks for your time.

Sorry about poor english.
