12V 4 Pin PC PWM Fan Controller with 2 Way Splitters | Reduce High CFM Fan Noise, Speed Control, Max 36W for Computer NAS Server High Velocity Industrial Fans
Compact & Flexible 12V 4-Pin PWM Fan Speed Controller (NOT Compatible with 2/3-Pin Fans)
4-Pin PWM Fan Speed Controller: improves compatibility of high-speed industrial fans with standard motherboards. Highly flexible controller for 4-pin PWM fans that can both work on its own for manual speed reduction and also work in tandem with the automatic motherboard fan control
By adjusting the fan speed control dial, users can manually set a PWM duty cycle from 0% to 100%, or reduce the PWM duty cycle supplied by PC motherboards to run fans slower than the automatic motherboard fan control would allow. The brightness of the green status LED provides visual feedback on the current dial setting. While most fan controllers are voltage based, this unit adopts the advanced Pulse Width Modulation (PWM) technique for more precise, efficient fan control and lower minimum speeds, regardless of the fans starting voltage
Powered by 12V PWM input, this controller provides 4-Pin PWM output. Limited by the pin specifications, the maximum output power is 36W.
