Here I am with a newly built custom desktop. Constructed not by me yet, EVGA Flow Control doesn't work. I don't know which header the AIO pump is connected to on my ASUS motherboard. I do know it is not connected to the four-pin AIO header. The wiring was installed so neatly; I am not ready to undo it.
I have been reading the various forums on this subject and am always interested in finding a fix. The CCVI device was not showing though I finally corrected this, yet I still get the CPUWB device not found. I might add, I read in one of the many forum posts about this and am successfully using another manufactures software. I now can assign RGB color, and all case fans and CLC 240 are operating. I am maintaining suitable CPU temperatures. Intel I9. Average 33-40C with no complex processing. Even then, I have only seen 55C. So I would think the AIO pump is working.
I will watch the forum, yet this issue has been ongoing for quite a few years.
