For my ITX build I've got a Fractal Design 202 case with an ASRock Fatal1ty B450 mobo attached. I've had the build done for awhile but ran into issues with overheating. I noticed the mobo has a header for the CPU fan, and another that says AMD fan LED header. There are also two for chassis/water pump fan connector.

I bought two of each of these fans:

to put in the case, as seen in this reddit post:

I'm installing the two small fans in the CPU area first and I'm having trouble figuring out which header to connect them to, and whether to leave the CPU fan plugged in by itself. Each fan comes with its own Y splitter. The OP of the reddit thread gave me this info:
For CPU fans:
Fan1+Fan2=Splitter1
Splitter1+Fan3 = Splitter2 > motherboard
For GPU fans:
Fan1+Fan2=Splitter3>4 pin Extension> motherboard
But I can't make heads or tails of that, and didn't want to keep pestering him.
