"The NA-FH1 is compatible with all Noctua 12V and 5V fans, as well as many third-party fans, and comes with a NA-EC1 4-pin PWM input cable for connecting to the fan headers; the controller reports the RPM of any fans installed in port 1 back to the motherboard. The NA-FH1 can be connected to the NA-FC1 fan controller as well if you want manual or smarter fan control over what your motherboard alone can provide."
