Questions about Noctua NA-FC1 Fan Controller

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.

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). Greetings

The upper one, which is not visible in the pictures. You can find it best in the document under Setup: https://noctua.at/pub/media/blfa_files/manual/noctua_na_fc1_manual_en.pdf

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/ Greetings .kure

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.
