This is the second Derale fan I've bought for my 1994 Mustang. This fan only covers half of my Mishimoto radiator, but leaving it on doesn't get the car over 165 degrees. The fan pulls a ton of air and is a bit noisy, but no louder than my 408 with a 3" exhaust. However, the first fan mechanically froze and broke the circuit after 1500 miles. To be honest it has been over a 5 year period where the car has not been moved much and has been parked outside.
