Reduced Power Consumption
Pulse Width Modulation technology allows your computer's motherboard to send information regarding cooling needs directly to the fan. This helps ensure that your fan only runs when necessary and only at a speed that will provide adequate cooling. This can save you money on your electric bill.

Easy Installation
The StarTech.com computer case fan fits easily into a computer case or other enclosure to keep your electronics from overheating. Installing your fan is as easy as connecting the four-pin connector to your motherboard.

Reduced Noise
Computer fan noise can be a nuisance. Because this computer case fan only runs when necessary, your work environment won't constantly be disturbed by noise. When the fan is operating, it runs at the lowest speed necessary to control the temperature of your computer case. Running it at a lower speed will also cut down on fan noise.
