Having a 4 pin fan connected to a 4 pin socket is ideal since 4 pin connections allow your fans to be controlled through pulse width modulation or pwm.
Internal pwm fan controller.
The three noctua fans are model number nf a4x20 with 4 wire pulse width modulation pwm interfaces to allow for speed control.

The fan controller was sourced on ebay here.
Pwm stands for pulse width modulation.

This was a well spent 21 not including the two new nf a14 s purchased on the same day.
They just shut down and stop spinning and that is why often the declared speed range of the fan can only be achieved by using pwm regulation.
They use an integrated circuit to control the speed of a fan or pump.
They don t die literally.
11 4v to 12 6v rgb led.
If you do not use the pwm feature such as when we install one in our power supply the fan will operate at full speed when the power supply decides to turn it on.
2 97v to 3 63v 4 5v to 5 5v fan.
Well almost all fans die if the voltage is lowered under 5v but with pwm control the fans can reach really low operation speeds of 300 600 rpm.
Pwm fans and or pumps are found in some cpu coolers and gpu aka graphics card coolers.
If your motherboard only has 3 pin connections though you can sometimes control the fans by changing the voltage supplied to the fan.
Corsair commander pro is designed with six 4 pin fan ports with voltage for six fan connectors and pwm control so you can monitor both 3 pin and 4 pin fans.
15 50 x 69 00 x 133 00mm power input.
This fan controller has also got four thermistor inputs for temperature control of different pc parts and supports two rgb led channels with sequential marquee strobing and visor.
I highly recommend the noctua na fc1 4 pin pwm fan controller for those needing to add more pwm fans where there s an inadequate amount of ports only one will do for many.
