DC fans operate on a direct current and provide variable airflow for cooling electronics, telecommunications equipment, automotive components and other mechanical equipment. 70mm direct current fans use significantly less power than AC fans of the same size and have a quieter operation. DC fans also produce low electromagnetic interference, making them an ideal choice for sensitive electronic devices and components.
70mm DC Fans Provide High Efficiency with Low Operating Noise
We design and manufacture 70mm case fans that combine high efficiency and quiet operation for use in a range of commercial and industrial applications. The housing and blades of our 70mm case fans are manufactured from UL 94V-0 P.B.T. thermoplastic material and feature UL1007 #26 or #24 AWG lead wire. 70mm direct current fans also include an option of 2-ball bearings, Sintetico bearings or sleeve bearings, depending on the model selected.
Before selecting a 70mm CPU fan, you should determine the amount of heat generated by your component and the amount of airflow required to provide enough cooling. Your power source is also an important consideration, as DC fans require the use of a transformer to convert AC electricity to DC.
Our 70mm DC fans are designed for high performance with wide operating voltage and temperature ranges and a long operating life. View the specifications below to find the 70mm DC fan that meets your size and operational requirements or contact us to learn more.
