I'm building my first PC with an ASUS TUF B850-Plus WiFi motherboard and a be quiet! Pure Rock Pro 3 CPU cooler. After connecting the first fan, I found a cable that doesn't seem to fit any RGB header on the motherboard. Is this cooler supposed to have RGB, and where should that cable be connected?

Double-check the exact cooler model. The regular Pure Rock Pro 3 has no lighting connection, while the LX version includes ARGB fans. If you have the standard model, there’s no RGB cable that needs to connect to the motherboard.
The standard Pure Rock Pro 3 comes with plain black fans and doesn’t have RGB lighting. The RGB-equipped model is the Pure Rock Pro 3 LX, which uses an ARGB connection. If your cable has fan connectors rather than an ARGB plug, it may simply be part of the fan daisy chain included with the cooler.

That was it—I didn’t realize the cable was for daisy-chaining the fans rather than RGB. Thanks for clearing that up!
