1、Equipped with 3 way computer fan control, which can monitor and control the temperature of computer and other equipment. 2、Intelligently test the computer temperature, the controller can automatically increase or decrease fan speed when CPU is too hot. 3、When the computer is standby or the detection point is within the standard range, the fan speed is automatically reduced to reduce fan noise. 4、The fan speed can be reduced or increased by manual setting to adjust the computer temperature. 5、Manually set the alarm temperature, the range is from 40 to 90 degrees. When temperature exceeds this range or the fan is stuck, an alarm will sound automatically, which can effectively avoid computer hardware damage due to overheating. 1 x Front Panel4 x Screw1 x Sticker Item Type: Computer Fan ControllerMaterial: ABS and Printed Circuit BoardModel: 33C03-RTKInstallation Position: Chassis Optical Drive PositionPower Supply Interface: Large 4 Pin InterfaceFan Interface: 3 Pin InterfaceControllable Fan: Can Control 3 Groups of FansCable Length: Approx. 60cm / 23.62inLuminous Color: ColorfulInput Voltage: 5V/12VOutput Voltage: 5V-12vPower: 10W
