I did this last week. I didn't expect any major differences, but I like to know I am not spinning a mechanical fan 24/7 when it isn't even needed. I think calling it a V-6 fan makes it sound weak, but it is not. When it kicks on it moves a LOT of air. It will have to be summer to know if it is up to the job.
Just FYI you don't have to do this mod to delete the mechanical fan.
I wish I knew a way to measure the cfm of both fans...
