If you have L-connect installed try checking 'Force Apply', or if you haven't done step 2, go do it.One-by-one set the controllers to 100% and find which controller ramps up your fans.Inside Fan Control app, set all your fan controls to manual.This step is pretty much self explanatory. Step 3: Find the corresponding controller in the Fan Control app If you're using an earlier version of L-connect, I'm not sure if there's something similar but hopefully there is.At the top you should see MB RPM Sync and turn it on.Get the L-Connect software, I used L-connect 3.Step 2: MB RPM sync in L-connect software I plugged it into one of the CPU headers, but you can try to plug it into case fan headers although I haven't tried it myself.This PWM connector should've come inside the box along with the controller, it's the one bundled up with the ARGB header (you don't need to plug in the ARGB header).I plugged in the PWM header from my L-Connect fan hub to my motherboard.For my use case, I just want to control all the fans, and if there are any other fans that I want to control individually, I just plug them into a separate PWM header on the M/B Step 1: Plug in the Lian Li hub PWM connector You can't really control each single fan/fan group. Note: This only works if you want to control ALL the fans connected to the hub.

Your results may vary, but this solution worked for me. Hello, I have discovered a workaround for this.
