I just bought my first ASUS motherboard. ASUS ROG Maximus XI Hero, and the readout on it has a constant A0 and never changes. Is this a BIOS issue or some sort of sensor? I was having issues with the system not detecting my CPU fan (watercooler AIO) and so i disabled that sensor and Im not sure if maybe that had something to do with it?
