Hello, I've recently rebuilt my pc and decided to get a 3 pack of Fractal Design Prisma AL-14 LED PWM fans. The mobo is a ASUS ROG STRIX B450-F GAMING. Originally I thought I could connect the fans to the RGB HEADER(S) and control them all using AURARA sync BUT I've since learned that those RGB Headers are 12 V and only for LED strips. So, how on earth can I connect my fans up so I can control the fancy schmancy led's??? Is the a 5V header on the mobo I've missed?
