I've come across CPAP machines in thrift stores and estate sales before. They have extremely rugged stepper motors in them to run the fan at varied levels and are very, very quiet because the whole thing is silenced with closed cell foam. They're rated for thousands of hours of use, but are often barely used because people hate them.

I've wondered about creating a forced air cooling system with one of them. I guess you'd need to build a stepper motor controller with access to the computer's temperature sensor information, so it could raise and lower the output of the fan based on temps. Or just set it up to run full blast all the time.
