Lian Li AL120 V2 fan wiring guide - single fan connections and logic for upto 16 fans

Here's a video on the Lian Li AL120 V2 Unifans and how to wire them with all the logic you'll need for sorting out up to 16 fans. I'm starting by showing you how to connect a single AL120 V2 fan and then moving into multiple fans and the logic there both with and without the triple pack connector.

The Lian Li AL120 V2 fans feature a number of interesting things worth knowing. They include an interlocking mechanism so they can easily be connected together. This means you can connect groups of fans but only have two wires coming out to control the power and RGB lighting. On a single AL120 V2 fan this cable can be connected directly to the CHA_Fan or SYS_fan on your motherboard for power and then the other cable has an adapter for the 5V RGB header which lets you control RGB lighting from your motherboard software.

Note, you can also use these fans with an all in one cooler and I've shown the logic of doing that here -

It's important to keep in mind the power requirements of the fans if you're not going to be using the controller from the triple pack as this could impact how many fans you can connect to a single header on your motherboard.
