How To Connect PWM Speed Control Correctly

In order to better control the speed of the cooling fan and reduce noise, PWM speed control technology is widely adopted. Properly connecting the PWM speed regulation function of the cooling fan can not only effectively reduce temperature, but also provide a quieter working environment for the device. What if PWM speed regulation is correctly connected? The following steps need to be noted:
1. Determine the fan type: Firstly, ensure that your cooling fan supports PWM speed regulation function. Although most fans now support it, it is best to check the specifications or user manual of the fan to ensure that everything is safe.
2. Connection control interface: The cooling fan usually has two power interfaces: one for power supply and one for PWM control. Confirm the power requirements of your fans and connect them according to the requirements.
3. Motherboard or controller: If you are using a modern motherboard, it usually comes with a fan slot that supports PWM speed regulation. You can connect the fan to the corresponding fan slot. Usually, these slots are labeled with the words "CPU-FAN" or "FAN", but the specific markings may vary depending on the motherboard. If there are no suitable slots, you can consider using a PWM fan controller to control the fan speed.
4. Settings: Open BIOS or motherboard settings and confirm that you have enabled PWM fan control. Usually, this setting can be found in the "Hardware Monitoring" section of the BIOS. Once enabled, you can use relevant software in the operating system to adjust the fan speed.
If the PWM fan is incorrectly connected or configured, it may cause the fan to malfunction or overheat. So it is important to correctly connect PWM speed regulation.
