About Computer Fans
Computer fans are used to cool computers and their associated components. They blow air into or out of computers and onto computer components in order to keep hardware at the correct operating temperature. Computer fans can be simple blowers, AC or DC fans that range from a few volts (V) to several hundred volts, or used with processors and power supplies. They can be large or small units, and either stand-alone devices or part of a heat sink. Typically, computer fans are very quiet and use DC brushless motors at either 5 or 12 VDC. Products with built-in temperature sensors can vary their speed accordingly. Common features for computer fans include lights and colors.
There are many different blower configurations for computer fans. Choices include axial, tube axial, vane axial, and multistage. Axial fans move air parallel to the axis of the fan and provide relatively high flow rates and low pressures. Tube axial fans feature a cylindrical housing with a propeller type fan. Vane axial fans feature a cylindrical housing with an outside diameter (OD) of blade tips that fit closely within the housing. This highly-efficient design provides a high-pressure capacity. Computer fans with multistage blowers produce very high static pressures at a low flow rate.
