I have the Z77 Extreme6 with all fans running normally.
Here is where my motherboard may be having trouble recognizing what is plugged into my CHA_FAN1 socket:
They are both the same thing: A 3-pin-to-6x3-pin fan Y-splitter. I have six 40mm fans, each plugged into one of those 6 cables. The other end of that Y-splitter is plugged into CHA_FAN1.
All 6 fans run normally. Unfortunately, in my UEFI, where Chassis Fan 1 Speed is located, it reads N/A. The other fan speeds are displayed normally.
I have yet to test the CHA_FAN1 socket with a single fan plugged directly into it; but is is quite possible (if not obvious) that the fan speed can't be determined from that socket because there are simply too many fans plugged into that one socket, via the splitter? All 6 of my 40mm fans are exactly the same brand and model. I've tested that splitter with one fan plugged in, and the CHA_FAN1 speed still could not be read (still N/A).
