It's 12V 0.30A  Brushless Cooling Fan. Electronic cooling fans circulate air in order to keep electronics such as computers and appliances cool. This cooling fan is both quiet and efficient. It has four mounting holes. This Brushless Cooling Fan is powered by 12V DC. They're also used in HVAC (heating, ventilation, and air conditioning) systems, telecommunications, military, and general industrial applications. Uncontrolled heat generated by electronic equipment not only degrades system performance but can also lead to system failure. To avoid this problem, your equipment must be designed with an efficient cooling system in mind.
