Summary: I used this fan as a upgrade on a Dell Deminsion 4300. Mounted fine in the oem fan shroud for rear tower exhaust. The fan is not as thick as the oem but worked fine with no audible vibration issues. Moves plenty of air and not too noisy, but I have not stretched it out by no means.
Summary: The selling point of the ThermoFlow series of Vantec is the little thermistor in front of the fan, which detects the internal case's temperature and the fan will throttle its speed to find a balance between cooling and noise output. This fan blows a nice amount of air and is not too loud.
Summary: Designed for moving the most air possible - and it does move a lot of air for maximum cooling. However, its noisy compared to other fans. Good for servers where cooling is required and noise is a secondary concern.
