Figure it out by following the manual? You'd think that'd be a basic life skill but people repeatedly prove that wrong. Case in point, OP.

I've had some experience handling PC hardware, but that was from a dozen years ago. I'd never seen a Radiator before, or RGB wires, let alone building one :D

For the Radiator and the Motherboard, I followed exactly what was written on the manual. DeepCool did an amazing job explaining things tbh.

And the MOBO manual helped a lot with Intel socket (first time doing an LGA socket) and Case wirings.
