No Fans reacted to Identify PWM Controller

[HarrietHubman]

None of my fans reacted to it when I set to 100%. I have 2 sets of 2 fans, 2 on Sys_Fan_4 slot, 2 on Sys_Fan_5 slot. Neither reacted. Not sure what to do as that's sort of the first step to doing anything else.

I'm having the same issue with my MB, Sees everything, says it's adjusting but fan speed doesn't change.

Installed Nuvoton NCT6687 Driver and everything is working now.

Ya I installed that as well and it fixed it.

BUt, as a word of caution, I ended up later having serious issues that were eventually fixed with a new Bios install for Mobo. Not sure if somehow installing this driver caused it, but I'm still using it again, and it's working again. Just a word to the wise... if you start having problems, maybe could be the bios got fucked up somehow by this, not even sure if it's possible. Or that somehow just reinstalling the bios fixed it, idk.
