I would like to use the MasterLiquid Pro 280 paired with an ATX power supply and a PWM fan controller in a cooling application without a PC motherboard.  However, I cannot find a 4-pin PWM fan controller; I've only found 3-pin controllers (some of which claim to use PWM over the 3-wire connections).

 

If I use a 3-wire PWM controller with the 4-wire MasterLiquid Pro 280, will I damage the control circuitry on the pump or fans?

If I use a 3-wire voltage-varying controller with the MasterLiquid Pro 280, will it damage the pump or fans?

If so, could you recommend a fan/pump controller for me to use?

 

Thank you,

 

Adam J.

The pump and fans will work fine, but will run at max speed. (unless you set a lower voltage)

It won't damage the pcb.

Yes, that can work. 

One note: the fans might give some clicking sound - but this was fixed on later production models I believe.
