Enermax Liqmax II 240mm Question

[IceBergs]

I have the Enermax Liqmax II 240mm and the pump is a 3 pin. The pump is a bit noisy in my opinion but i have it hooked up to a 3 pin header. Should I have the pump running to the 4 pin CPU header even though it's only a 3pin? Will it help noise?

Connect the pump power connector to the motherboard.
Notice: If you recognize that your mainboard's CPU fan or PWM sockets do not provide enough voltage to power the pump, please use the included 4-pin Molex adaptor and connect the pump directly to your PSU.

Try the molex adapter and see if the power source straightens up the noise problem from the pump.
