Product review (5 stars): Great Universal Option
Before ordering this I had read some reviews that said the motor was extremely loud. It comes with several rubber spacers that go between the fan blade and the motor. I used the one that fit my setup and have no issues with noise. The motor is very quiet--at least for my setup. There were plenty of adapter type parts as well as mounting options for different setups. This motor goes for as high as $180 so you can't beat this price. It's been running for over a week with no issues.
