It needs to have atleast a 10 deg spread to work well. In other words it needs to come on at say 185 F and shut off at 175 F. If you have the cheaoer switch with a narrow window it will keep turning on and off and shorten the life of the fan significantly.
For correct testing, drive with ac on on a 90 deg day and see if that fan still works :). I suspect it might on a na but on a tt forget it.
