Slim Pickens
I Blue my mind.
I have a 6" Vortex fan and a speed controller.It bothers me a bit that when operating the fan through the speed controller I notice a distinct hum.The hum seems more pronounced as the speed is dialed down to slower cfm's.Maybe it's because at higher speed,the noise of the fan covers most of the hum.
Anyway,I have heard mention of Variacs over the last few years,and wonder if that might be a safer solution?My problem is that I am unsure of what to buy,as there are different configurations.I see some that are 500w which would be more than adequate for a fan drawing 72 watts,but on the other hand they are only rated to 6amps or so,and the fan specs say 6.68 amps. Here is a link to some of the Variac offerings on Ebay,if anyone cares to look.

I am at a loss as to what to consider...if anything.
