Hey, I installed the AIO but firstly there is another cable on the pump which I couldn't connect. I have connected the CPU fan, PUMP and RGB and everything is working except for the digital display. What is the fourth cable for? Does it have anything to do with the display? And where should it go? It is not mentioned in the instructions. Secondly, I'm not sure if I'm using the right driver. According to some reviews on Amazon, this is the same programme as for other digital AIOs. However, the driver does not recognise the device. Possibly because of the fourth cable?
