Simple Troubleshooting
All the devices connected to my splitter work at 100% but I cannot vary their speed
- Check that the splitter mini-4 pin PWM signal cable is correctly connected to the CPU_Fan connector of the motherboard
- Enable Manual Fan Control in the motherboard BIOS
The device(s) connected to my splitter do not work
- Check that the splitter power cable is connected to the power supply
- Check that the non-functioning device female 4-pin connector is correctly inserted in all 4 pins of the splitter connector: in effect, it may be possible to inadvertantly offset the female connector by one pin by slghtly forcing its insertion, so be careful about this!
I am getting a CPU fan error when I turn on the computer
- Make sure that a device is connected to channel 1 of the PWM splitter. If the motherboard CPU_Fan header does not read an RPM signal, it will return such error by default.
- Check that the device connected to Channel 1 of the PWM splitter is correctly inserted in its connector.
- Check that the power cable of the PWM splitter is connected to power supply.
I connected the PWM splitter to an auxiliary 4-pin connector that was indicated as PWM capable by my Motherboard manual, but I can't vary the speed of my devices
- Other than the CPU_Fan connector which is PWM enabled by default, most of the motherboards 4-pin connectors feature two methods of speed adjustment in order to allow control of both types of fans, the 3-pins which are voltage controlled, and the 4-pins which are PWM controlled. As a result, the PWM functionality must be enabled in the BIOS before it can actually work. Please consult your motherboard manual for a how To.
- Since the CPU_Fan motherboard connector is PWM enabled by default, we recommend that you connect the splitter to the CPU_Fan connector in order to ascertain its functionality.
I am connecting the splitter to a PWM fan controller instead of the motherboard, and it doesn't work
- Not all PWM fan controllers are compatible. Please read this white paper for further explanations and a list of compatible devices.
