Hello, welcome to building your PC for the first time. Your ASUS Prime B450M-A/CSM board has a CPU fan header and two CHA_FAN headers with four pins each. You’re planning to add four RGB fans but seeming to have limited header options. A fan splitter could work, though you’ll need to confirm compatibility with the Aurora Sync system. Fans from Amazon are typically three-pin, so you’d want to check if they can be adapted or if a different setup is best. Make sure to verify all connections carefully to avoid issues.
Hey. Well to start off. CHA means CHASSIS. These are the fans you'll want on your chassis (or PC case if you will). I don't think the RGB is controlled via fan headers?? But rather RGB headers, look for the white headers that look like fan headers only they're white. Yours are 4 pin so you gotto make sure you got compatible 4-pin RGB fans (Corsair will not work unless you buy their RGB controller). Fan splitters work fine though but not for RGB.
