The 80mm SmartCool - Thermally Controlled Case Fan from Antec adds intelligent cooling to your computer. The fan features an integrated temperature sensor that increases fan speed as the temperature of your computer rises. This allows the fan to cool your system when needed.
Variable Speed
The fan's speed varies based on the temperature of your computer. This allows it to spin faster when it is needed and to spin at slower, quieter speeds when the computer isn't very hot.
Temperature Sensor
The fan features an internal temperature sensor as well as a connection to your computer's motherboard. The motherboard signal connector allows your computer to control the speed of the fan based on temperature.
