Over the years I have used plenty of Sunon Fans in all sizes and flavors and have to agree with Max in that I never saw a Sunon with 3 wire tach output.The Sunon site show nothing but two wire fans!

Am using the fan with 3 leadsif you change to the other type of fan, the one with three leads, the third lead is a temprature sensor, that would give you the most important information, whether the fan was cooling or not.
Am using the fan with 3 leads...Where exactly on the fan were you thinking of obtaining the square wave?
