My first water cooled pc and I'm stuck on how to address powering my fans. I have 11 ql 120's, 2 ql 140's and 2 tt 140's that came with the 900 tower. the tt fans I have under control, just wondering if I should use splitters off the mobo or get a hub or two? Mobo is an amd Radeon 5700xt. Has the cpu(auto), pump(pwm) and 4 system fan headers(dc). The pump and system headers are addressable and I can change them to either pwm or dc. Looking for a clean and easy way to power the 13 fans. Already have it all built but the power to those fans so I'd REALLY would like not to have to drain both loops and redo my current cable management. Any and all recommendations would be highly appreciated. Thank you :)

Welcome to the forums, newcomer!

You should use a PWM fan hub, probably 2 fan hubs hooked to two WM fan headers on your motherboard. Make and model of your motherboard? RX5700XT is the discrete GPU.

My bad on the mobo description. It's a x570-a pro. Besides the cpu header, it has a pump header and 4x system headers. I can switch those headers to pwm in the bios. the pump header by default is pwm, the system headers are dc by default
