Hi
My knowledge about AIO liquid coolers is almost nil. Here I refer to Cooler Master ML120L RGB AIO cooler.
There's this connection diagram where I see the two fan pins from Pump & Fan connect to the Fan headers on the motherboard.

There's another cable which I think is for RGB lighting (Please confirm so) that interconnects with N M & O parts as shown in the diagram.
Now if I do not want any RGB lighting, can this part be simply kept disconnected?

Is there any necessity that RGB part must be connected for the Fan & Pump to function? It seems as per the manual, O part further connects to a SATA power connector from PSU.

Detailed manual can be downloaded here. It's all pictorial. No further explanation is provided in the manual.

Thanks.
