Actually that line includes six models, two each in the Taichi, Master and Fatality groups. ALL of them have one each of BOTH types of headers - plain RGB and Addressable RGB. So from the mobo's standpoint, you can buy RGB components from either or even both types. Of course, if you buy some of each type, the units must be connected to their matching mobo headers.
RGB Fans as a class really are TWO devices in one package. There is a fan with a motor and its cable to connect to a mobo CHA_FAN or SYS_FAN header for power and speed control. Separately there is a second cable for the LED's built into the frame, and that connects to a mobo plain RGB or ADDR RGB header, depending on which type of RGB system is in the frame. When you connect those to the mobo header, then you also must load onto your system the mobo maker's software utility that powers and controls displays through the header. In the case of ASRock, that is called their Polychrome RGB utility. Now, those two statements assume that you want to power AND control both the fans motors and the RGB lights from the appropriate mobo headers, and not from third-party control systems.
You CAN get third-party controller boxes or Hubs to do that power-and-control job for your RGB devices and some of them may create different displays that your mobo's software does not. But for the most part, those boxes are useful if your mobo does NOT have any header on it compatible with your RGB lighting system.
What does cause some worry is that a mobo (like yours) has only ONE header of the correct type, but you have several RGB devices (e.g., three RGB fans). But you don't really need a Hub to solve that. A FEW RGB fans come with extra connectors on their cables so you can daisy-chain them. But more commonly you just need to buy an RGB Splitter. It is similar in concept to a Fan (motor) Splitter, but different for use with RGB light systems. You can get them with 3 or more outlets from a single input from a single header. Most plain RGB or ARGB headers can supply up to 3A total current - check your mobo manual for exact limits on max current and length of a light string, if you have one. Usually that will handle 3 to 5 RGB Fans' lighting units, so no problem.
If you have a LOT of RGB devices that will demand more current, then you may need to get into third-party Controller / Hub units that can do that. Even among those you may have some choice. Many allow you to use EITHER their own control box or software tool, OR to connect a cable from your mobo's RGB header (of the right type) to their control box so the mobo software's controls for displays are relayed through the extra box.
Bottom line, unless you are planning something very complex or huge, you can buy almost any RGB fan you like because your mobo has BOTH typed of RGB header for you to use. Just take a close look at the specs or the photos of the connectors for the RGB lighting parts of the fans, to see if they are the same as the headers on your mobo. If in doubt, post back here with specific models, or contact the fan maker's Sales or Tech Support people and ask whether their units have the connectors commonly used now for plain RGB (4-pin, 12 VDC system) or ADDR RGB (3-pin, 5VDC system), or would you need some kind of adapter.
