I bought the Lian Li UNI FAN TL Wireless LCD. As you can see, there are three cables. Is cable 1 the PWM cable? Is cable 2 the 2-pin connector? Where on the motherboard should I plug cable 2 into? I’m a complete beginner at PC building and I’m not sure what to do. I’d really appreciate it if someone experienced could explain it to me in detail. Thank you!
