- Note: The four wires consist of the negative pole of the power supply, the positive pole of the power supply, the speed measurement signal line, and the PWM control line. Firstly, the power supply line of the fan should be found. Generally, if the fan has a red and black line, then red is the positive pole of the power supply and black is the negative pole; If there is no red fan, it is usually the positive pole of the yellow line and the negative pole of the black line. After the power is turned on, the fan runs at full speed. When the other two wires are connected together (not elsewhere), the fan speed will significantly decrease. Disconnect these two wires and connect the control wire to the negative terminal. The fan will run at a lower speed (some fans may stop running). Note that this last step can be used to locate the control line, as the speed measurement line connected to the negative pole of the power supply is unresponsive. The control and speed measurement cables of the fan cannot be connected to the positive pole of the power supply!

1. Take control of your cooling system with our PWM Fan Temperature Controller. Designed for 4-wire PWM fans, this 12V3A temperature-to-speed display controller ensures your fan operates at optimal speed, adjusting as temperatures change. For reducing noise in PC cases and servers while enhancing energy efficiency. 2. Our DC speed controller module offers both manual and automated modes, allowing for precise control of fan speed based on cooling demands. Whether for industrial use or high-demand environments, adapt your fan's performance to meet any situation with ease. 3. With the capability to display RPMs in increments of 100, up to a maximum of 30,000 RPM, this fan controller for applications requiring high-speed fan operation. Monitor and control your fan's speed with accuracy, ensuring your system stays cool, even under the most strenuous conditions. 4. Equipped with a 42cm (16.54 inch) temperature probe, our PWM controller provides continuous real-time temperature readings. This allows for automatic fan speed adjustments, ensuring your system maintains low noise levels and optimal cooling performance at all times. 5. Please note this controller is exclusively designed for 4-wire PWM signal controlled fans, conforming to the 25KHz 5V signal standard. It's compatible with conventional PC cases, CPU fans, and many server fans. However, it cannot control 2-wire or 3-wire fan speeds, ensuring your setup meets these specifications for optimal performance.
