The reason All Black Sleeved PWM Fan Splitter Cable 1 to 2 Converter, 2 Pack3/4 Pin PWM To Dual PWM Power Y-Splitter Adapter Cable for CPU PC Case Fan 1.PWM version of the two-wire cable version of the snake 2.Protected fan interface 3.Easy to achieve 4Pin PWM temperature control fan in parallel, make full use of a limited number of motherboard 4Pin interface, 4.These 30cm extension cables allow you more choice in where you want to position your PWM or standard 3 pin fans inside your case. 5.The wires are 30cm sleeved in black braiding with a 4pin female connector at 1 end and splits to 2 4pin male connectors at the other. 6.Please ensure your motherboard fan header is capable of the additional electrical load before purchasing any of these. 7.Please note - all the connectors are 4 pin connectors , but one of the connectors only has 3 wires. The reason for this is that the sensor wire is not used on this connector as if both fans were sending back information to the mobo it would not be able to understand 8.the information as both lots of information would be coming back through the single connector. 9.What happens is the fan with all 4 wires tells the mobo the information , and then the mobo controls the speed of both fans. 10.These do also have a cut out so you can use 3 pin fans instead of 4 pin if you wish. Item: Fan Power CableColor:blackSize:30cm/11.8inch Package Included :2x Fan Power Cable Question:Why does one split have a pin missing? With the missing pin, can it still power a 3 pin fan?The missing pin is what the motherboard uses to read the fans speed. As it can only read one, only one header has that pin. The 4th pin is PWM. The remaining two are power and ground, which is what a 3 (or 4) pin fan runs on, so yes, it will power a 3 pin fan. Can 3-pin fans be used with this adapter? im using two corsair rled fans and two that came with the 100r case.This will allow you to use both fans, but beware, it will not allow you to adjust the fan curves at all. I used several programs including the MOBOs own settings to try and change it. I’m sorry i wanted to know the fan splitter one has 4 pins and the other 3? Is that normal or it’s missing the pins?Thats how its supposed to be. The 4-pin header includes a "TAC" (tachometer) signal that goes from the fan to the motherboard so it can report the fan RPM. The motherboard can only read one fan or the other, so plug the fan you want to read into the header with 4 pins. The fan on the connector with only 3 pins will still get power, ground, and the PWM control signal from the motherboard, but you wont be able to measure its RPM.
