ACPI fans gone after updating BIOS to 3202

I just updated my Maximus VIII Impact BIOS from 2202 to 3201 replicating in the new BIOS the exact configuration I had in the old one
Upon restart I noticed that all my Windows 10 ACPI Fans and Thermal Zones have now disappeared (see attached images before and after update).

The system seems to be working OK so I'm wondering if this is by design or a bug in the new BIOS.
I read quite a few complains about 3201. Perhaps I should just flashback 2202 (which was very stable) and wait for a newer one.

I think its a bios bug. I have same issue here in Ranger VIII with 3201 bios. When I try renable in Monitor tab, my bios freeze.

I tried that. I also tried to flash back to 2202 (and the fans reappeared) and then to 3201 again: the fans in Windows 10 are always gone with BIOS 3201.

I'm using three Noctua NF-P14 FLX (non PWM) fans and they are all connected to the external fan module.
The following is my complete list of BIOS changes (from optimized defaults):


Advanced:
  CPU Configuration
     Intel Virtualization Technology    Enable
     CPU Power Management Control
       Intel SpeedStep                  Enable

  APM Configuration
    ErP Ready                           Enable (S4+S5)

    Ext. Fan(s) Configuration #3
	Q-Fan Control			DC Mode
	Q-Fan Source			PCH
	Speed Low Limit			200 RPM
	Profile			        Silent

Yes, 3201 seems pretty broken.
Flashed back to 2202 and waiting for new version.

I gave this one a shot for a couple days. Tried multiple update methods, cmos clear, fresh install, no luck. I see the same issues others have reported:

1) ACPI fan issues
2) Logitech keyboard does not work in UEFI, old Microsoft pos ergo worked ok if that ergo sux
3) inconsistent entry into UEFI using Windows troubleshoot method

I rolled back to 2202. Be patient guys - you are right, asus should not be putting out releases like this. But it is very difficult to find competent testers with access to wide ranges of equipment these days.

I can confirm that i have all these issues listed with my M8E, the only good thing since november 2015, period when i bought this motherboard, is the finally fixed shutdown problems that i had since building my newest pc, 9 from 10 times the computer was still running all the fans without going off completely.
