Connects up to 8 PWM devices (Fans / Pumps). Powered with SATA power connector. The function of this device is to connect up to 8 PWM devices (fans and/or pumps) to a single PWM fan conector on the motherboard, thus enabling speed-control of all connected PWM devices concurrently. We generally recommend to use the CPU_Fan connector of the motherboard,because most motherboard manufacturers usually allow a greater range of adjustments on this particular connector. PWM capable connectors must necessarily be 4-pin, but not all 4-pin motherboard connectors implement or enable the PWM signal modulation by default. Please carefully consult your motherboard documentation in this respect.Since only one RPM signal can be read by one motherboard connector, only channel 1 of the PWM splitter carries an RPM signal; thus the motherboard will only read the RPM signal of the PWM device that is connected to channel 1 of the splitter. The PWM signal cable has 2 wires: 1 for the PWM signal, and 1 for the RPM signal. Power to the PWM splitter is supplied by a SATA connector that must be connected to the Power supply.

  • Junction housing including: (8) Males 4-pin connectors - Channel 1 carries RPM signal
  • (1) Female 4-pin mini-connector
  • (1) Male SATA connector
  • Peel-off sticker
  • Mounting screws
  • RoHS compliant
  • 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 motherboardEnable "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

Worked great for my case/mobo
Worked great for my case/mobo. Mobo only had 2 system fan inputs, so i used this for the other 3 case fans. Fyi they will all run at the same speed so if you wanted some weird customized speed for each fan it won't work. But to keep the computer cool? Great.

Worked as advertised. Had to use the cpu header to get the speed control to work on my asus 760gma-p34 motherboard.

Works great. I use two of these to control my intake and exhaust fans. I run 9 fans in my in win 303.

It works perfect fixed my problem
Fast delivery. It works perfect fixed my problem.

Works best if used with same fans to control accuracy
Does exactly what you expect it to do, reduces 8x 4-pin pwm to a single pwm connector, while sourcing power directly from the psu (bypassing the mobo). Works best if used with same fans to control accuracy.
By Lola Webb
How many fans you want?
Works great!!! I thin im going to include this into every build.. Seems how board manufactures are skimpy on fan connections now days
By Tara Harper
Works great. Maintains pwm control of all my fans
Works great. Maintains pwm control of all my fans. Keep in mind your mb will see al the fans as 1 fan, so put only the same type of fan on this controller.
By Taylor Nguyen
Perfect for controlling many pwm fans at the same time
At first i was skeptical about this thingy, but it works amazing. My mobo had only 1 sys_fan header and a cpu_fan header, both pwm. I connected this adapter to the sys_fan (left the cpu one exclusively for the cpu fan) and connected 5 pwm fans and the 5 fans are working flawlessly.Note: you can't control fans indivudally, your system will only detect one fan (the one connected on the red header) and with that you can control the other fans at once. Can be through bios or other software like speedfan.My only issue is that the pwm connector is does not connect tightly to the header, feels like it can disconnect without force at all, but i believe it wont be a problem as i dont move my pc from place to place.
By Hunter Ma
Great just great
Great just great. I have 4 pwm fans but only one pwm fan header on the mb. Well this made my day, i was able to hook up all 4 and control their speed with speed fan app. Please note that only the red cap fan header is the one reporting rpm. I did not want individual control of each fan so this was perfect.Does the job not as pretty as the silverstone. Still good bang for the buck
