Hi everyone thanks for reading and taking time to help this rookie. So I'm trying to finish my first computer build. I have the coolermaster h500p, msi x370 gaming m7 ack, and also used the coolermaster masterliquid ml 240 rgb cpu cooler. The wires aren't labeled good so I'm stuck. Do i hook the front fans into the cpu cooler for the lights to sync? i connected cpu cooler to the cpu fan1, and the other is a connector from coolermaster pump on cpu i connected to the pump fan 1. so I'm stuck now where to connect last 3 cables from the fan which look like a 4 pin with no pins so I'm assuming it goes to motherboard and then 2 little cables i don't know what are called. Thanks for any help ill try and upload pics from my phone.

Coolermaster radiator fans - CPU_FAN
Coolermaster Pump - > PUMP_FAN1

The back exhaust and 2 front LED fans can connect to a 3 in 1 splitter behind the motherboard. The 4 pin connector goes through a top hole in the case and into a 4 pin RGB header. Video showing this here. Most motherboards called this JLED1. You want to make sure it's also being plugged in the correct way with the downwards arrow lining up with pin 1.

I can see why you're having trouble... the user manual is terrible.

It certainly does not sound right that you would connect case fans to the CPU cooler.

The case does come with a "1 to 3 splitter cable" (their name for it). Perhaps this will allow you to combine the case fans and connect to a single header on the motherboard?

The documentation also mentions that RGB syncing is only possible if you have an additional controller or compatible motherboard.

Some detailed pictures of the case cables would help us.
