MAA-KU DC Axial Case Cooling Fan. Size : 3.15" inches (8x8x2.5cm), (80x80x25mm), Supply Voltage : 12VDC (Black) DC AXIAL COOLING FAN Axial fans blow air along the axis of the fan, or parallel to the track of the blade axis. DC axial fans are found in a variety of applications, including computing, servers, telecommunication cabinets, and any type of equipment where the need for thermal control is necessary for the improved reliability and life extension of the components that are included in the system. Uncontrolled heat generated by electronic devices will not only decrease the performance of any system, but will ultimately lead to complete system failure. In order to prevent this catastrophe from occurring, it is imperative that your equipment be designed with an efficient cooling system in mind. This system will not only be crucial to heat dissipation but will also contribute to the stability and long life of the equipment itself. This is where a DC fan with a well designed cooling path becomes one of the most important components of any equipment. Heat dissipation for the prevention of premature failure is by far the most crucial part of any electronic system design, and a DC fan is one of the best tools available to keep your electronic devices performing at top operational shape. DC fan functions best under a low pressure or low system impedance environment. With reduced fan speed the noise produced by an axial fan can be kept at a minimum. Because of this low level of audible noise, as well as their economical price range, this kind of fan is extensively used in PCs, for both CPU and power supply cooling.
