Hello

Can anyone tell me how can I connect my Noctua NF-A14 PWM 140mm Fan 4 pin PWM to a 3 pin Fan Controller in my NZXT Source 530 case?

Can anyone explain how PWM speed control works?

I plan to buy the NZXT Sentry Mesh 5 Channel Fan Controller and wish to use this controller to control:
-x2 Noctua NF-A14 PWM 140mm Fans as intake in the front,
-x1 Phanteks 140mm Black Frame White Blade PWM Premier Fan as rear exhaust,
-x2 120mm case stock fans

Any information appreciated

Thank-you

The 4 pin fan side connector will fit on a 3 pin fan connector anyway.

Hello,

The 4pin connector will fit into the 3-pin header, please use the notch/guide to fit the connector, though the PWM won't work, the fourth pin (PWM) is the speed control.

Some site/forum, you may wish to read for your reference.
Hope this helps...

Thank-you for the reply however I am not talking about putting the 4 pin fan into the motherboard, I am talking about putting the 4 pin fan into the 3 pin fan controller - NZXT Sentry Mesh 5 Channel Fan Controller which, correct me if I am wrong I don't believe its compatible.

All 4 pin fans can be run off 3 all pin connectors. The 4th pin is for pwm control. One of the other 3 pins is for Voltage control. What will come out your controller is variable voltage which will change the fan speed.

PWM was made so its backwards compatible with existing 3 pin voltage control fans and controllers. PWM is more power efficient than Voltage control. eg PWM fan 10W, Voltage control fan 20W - controller plus fan
