INTRODUCING THE SONY WH-CH720N: Powered by the Integrated Processor V1 from our award-winning WH-1000XM5, these noise cancelling wireless headphones deliver superb sound

[Silent Fan Parameters] cpu Fan size: 124x120x25mm, speed: 2000RPM±10%, noise≤28.2DB(A), air volume: 68.9CFM, wind pressure: 2.21mm H2O, power supply interface: 4PIN PWM, light interface: 5V 3PIN, voltage: DC 12V, current: 0.17A, higher air flow can improve cooling performance, and keep the fan low noise [Positive Air Outlet Design] The fan blades of the M12Q series rotate clockwise, with the blade facing the inlet direction, providing a speed of 2000RPM and serving as the exhaust fan for the case. [PWM Intelligent Temperature Control] The cooler fan has a PWM temperature control function, after connecting the fan to the interface of the motherboard, there is no need to manually adjust the speed, the fan can automatically set the speed according to the temperature. [ARGB Infinity Mirror] The two sides of the fan are infinity frame structure, with a faulty light effect design, and a slender fault-style LED light strip on both sides of the fan frame, so that the fan has rich ARGB lighting effects. [Wireless Splicing] The new power chip module cable simplifies the cable management, reduces the cumbersome internal wires of the chassis, and provides powerful power for the fan, and the signal and power are transmitted between the fans through the contacts (Note: The cable of the control cable needs to be connected to the side of the fan with pins, do not connect to the other side)
