I used a usb cable with a 3 pin fan connector and a plug list with a usb charging connector.
I think there is a USB cable, I used to use it that way.

According to the specification, the thing can handle a maximum of 3A. At 3.8A it probably gets too warm. https://noctua.at/en/na-fc1/specification
I myself operate the fan controller on a universal power supply unit and can use it to regulate the fan perfectly. For the power supply, I cut one of the supplied cables and connected the power supply unit via a terminal.
Have fun tinkering! 😊
Hello you can connect it like this but I don't know if it works like this
It depends primarily on the available power of the power supply and the power drawn from the fans. If ok, I see no reason why this should not work.

Yes, the controller is installed between the mainboard header and the fan. Whether an additional power supply is necessary depends on the mainboard and the fans connected to the controller. The maximum load of a fan header of the mainboard should be apparent in its manual, usually around 1A. The current requirements of the fans can be found in their manuals or specifications. The controller comes with one connection cable without power supply and one with additional power supply via PC power supply unit. If in doubt, use the additional power supply.
You can see the package contents in the last picture where you can also see the splitter cable in the top right-hand corner.
It is intended for the PC internal power supply (12V/5VDC).

No, it is not USB powered. It would need a 3-pin USB cable, but unfortunately we no longer have this product in our range.
Hello Civiliano,
2 variants
- via SATA power cable (male connector is included with a small breakout cable in case PWM information should be tapped, but this won't work on the Mac Pro)
- via 4pin FAN header and some tinkering. FANSPEED seems to be handled differently on the Mac than on other motherboards and can't really be used. More about this here: https://forums.macrumors.com/threads/quieter-case-fans.1115475/#post-12131856 and tinkering instructions here: https://www.tonymacx86.com/threads/macpro-fan-pinout.122584/

The controller needs 4 pins to control the PWM signal for the fan. Only fans with 4-pin cables allow the speed to be adjusted, fans with 3-pin cables have a fixed speed.
So the cable connecting the controller to the fans must always be 4-pin, or the controller makes no sense. The power supply to the controller can be achieved with an adapter which taps the power at the PSU or other power source.
