HET 700 motor had serious vibrations, thought the bearings was bad but it´s the axle who to thin/small, this is made for a 90mm fan spinning 35000-40000 rpm, but the quality is far from what needed. Before I dismantled the motor I tested it with a HET 9305 fan, and it stopped at 25000rpm when it hit the housing, one blade on fan broken and the housing in lots of parts.
