[QUOTE="RussellR, post: 78077, member: 5189"] You can change the size of the capacitor on the fan to slow it down, the capacitor is there to effectively skew the phase on the motor and make it turn on a single Phase motor so by adjusting the capacity of the capacitor you can reduce or increase the speed, might take a bit of experimentation to get the right capacitor, but they are pretty cheap from somewhere like RS or Maplins, so have a look at the capacitor that is on the fan and get some different ratings to try.
