Good to see I'm not going insane. I just played around some with the lights in my new build and set up an Arc pattern on my fans and H115i Platinum. It seemed fine until I opened up Battle.Net and it started disconnecting every minute. Same thing happened when I downloaded USBDeview to find out what was disconnecting. I hadn't had the issue since I finished this build on Saturday so I wondered if something was failing!
Went back to color shift and I've not had any disconnects or anything since. I'll stick on this until an update is released to fix this.
