Title: Great cooling but noisy
Review: You can't beat these fans for cooling. The difference in air output between the Tornado and a regular 80mm fan is night and day. I placed 2 of these fans on equipment in an office server room. They provide much better cooling than the old fans. These are the most powerful fans I ever used, but they are also the loudest. The sound is comparable to a vacuum cleaner. I can hear these fans 25 feet down the hall from our server room. I'm considering getting a fan control to turn these down when I have to work in the server room. I definitely would not use these in a home environment without a fan control to throttle them down. According to the specs, the fan pulls 1 amp which is a lot of power for a fan. In conclusion, you can't do much better in terms of cooling, but the noise is likely a deal breaker for many.
