I finished my first build last week and it has been nothing but fantastic so far. A couple of blue screens but messing around in the BIOS fixed that. I'm still gettting "CPU fan error" whenever I turn on my computer, although there is really no indication anything is wrong beyond this one error. My BIOS still reports my CPU temperature just fine (hasn't even breached 35 degrees yet), I can see my CPU fan RPM's just fine, they seem to scale with CPU load just fine--everything is seriously fine as far as I can tell.
The only thing I can think that would be causing this is that my case (Fractal Design Define R6) comes with a "fan hub," Instead of connecting your CPU fan to the motherboard, you connect your CPU fan to this hub, and the hub then connects to the CPU fan slot on the motherboard. Then all other fans in the case can be connected to this hub and controlled through that. The hub receives power from a SATA cable. It's actually super convenient. I've never seen mention of a fan hub like this in any review video, build walkthrough, case overview, or anything else so I don't know a lot about them beyond their intended purpose. I followed my case's instruction manual very carefully when plugging things into this hub and every fan is working fine, so that shouldn't be the issue.
My full build is below. Any way to get rid of this error? Would like a clean startup without the brief error screen.
