If connecting the OCTO via USB to the motherboard, is there a limit to the number of OCTO's that can be used and programmed in the aquasuite? I have two separate loops and a total of 16 fans in my computer that I would like to monitor and control individually.
There may be a limit, but it will be well beyond your needs. Running multiple OCTO's is fully supported, each OCTO will have it's own tab in the aquasuite.
