not noisy at all. i have a DCC controller running my taurus fan. the controller doesnt even run the fan until the engine reaches operating temp. most of the time, i can hardly tell if the fan is running or not. the controller varries the speed of the fan and most of the time its below 100%. it does kick the taurus fan on 100% when it senses too high of an engine temp or anytime when the stock electric fan is on. when its on full blast then yah, it can be a little noisy. about what two stock e fans would sound like.
the taurus fan pulls crazy air. its more than sufficient to pull air through the radiator, condesor, and a large aftermarket trans cooler without any problem.
if you decide to get rid of your stock mech fan then its way easier to fit the taurus fan in there with the stock mech fan pully gone.
