3 pin fans in PWM splitter box?

[Silentseraph]

Hello,

I was looking into getting this 8-way PWM splitter box.

If I put 3-pin fans on this will it only run at 100% or would I be able to control their speeds?

Thanks

Your motherboard will be able to control the speed of every fan attached to the splitter box. But you will not be able to set each fan at a different speed.

PWM splitters(unless they have more elaborate hardware) get 12 volts off the power supply(to avoid overloading the board header) and thus a 3 pin fan will run FULL speed all the time. The only actually split the PWM wire(4th wire).

PWM fans run on 12 volts all the time and the PWM signal controls the speed.
3 pin fans control by changing the voltage the fan gets.
Both fan types report the speed via the 3rd wire. With a splitter, only one fan will report speed to the board.
