The overview of the technical data states that this fan has a 4-pin PWM connection. However, this is incorrect, only a short iCue-Link cable is included, which can only be connected to other iCue-Link fans. In addition to the cable, there is also no output for a 4-pin PWM cable on the fan itself. This means that the fan cannot be connected directly to the mainboard and you are deceived. Fortunately, I have a compatible Corsair water cooler and can still use the fan, but not without modification. The fan receives power via a DC cable and the Corsair fan hub. Shouldn't you adjust the description and correct the entry '4-pin PWM' connection?
