Pin configuration for ASUS aRGB board
Pin configuration for ASUS aRGB board
You're facing a compatibility issue between your motherboard's addressable RGB headers and the Deepcool cables. Since the headers are 4-pin but the cables only have a 3-pin connector, you'll need to either use adapters or modify the setup. Consider checking if there are compatible 4-pin to 3-pin adapters available for your specific model. Alternatively, you might need to adjust the cable connections or consult the manufacturer's support for further guidance.
You're curious about how many fans you can power from one header. I have 7 120mm fans and one aRGB AIO pump. There are mixed reports on LED counts and power usage, but the motherboard header can handle around 3 watts.
