NIHAKA 3 Inch DC Fan high Speed 12V PC Cooling Fan (Pack of 5) ALL IN ONE Cabinet Compatible with Computer  (Black)

This is a 70x70x20mm 12V operated 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.
