Lian Li Bora with lian li fan controller and remote. Can't figure out how to control fan speed

[Dunzaus]

Hi I can't figure out how to control the fan speed with this product. Does anyone know how to or have experience? In a Gamer Nexus review of this product: https://www.gamersnexus.net/hwreviews/3189-lian-li-alpha-550x-case-review-temperature-noise-vs-330 , it says this: 

''Fan speed is controlled via a PWM header attached to the motherboard, so the main benefit of bundling RGB/fan power together and connecting the fans to the hub is to reduce cable clutter. The exhaust fan has a normal 3-pin fan header and a molex plug, so even though there are empty slots on the hub, it must be plugged in elsewhere.''

 

But I still can't figure it out and fans are so noise atm

 

Please help

You connect fans to hub and hub to PWM header on mobo. Or you connect fans directly to mobo with PWM connectors. You can connect that 3pin fan to mobo too, those connections are backwards compatible. Just don't connect molex at the same time with 3pin.
