So I'm about at my wits end with this, this is such a bizarre issue. I've already submitted a ticket to Asus about this and they are "researching" why this is happening for the last 2 days but I've heard nothing back yet, so I figured I'd do the same for AIDA64 and see if there are any answers/suggestions/solutions or jokes to ease my insanity.
AIDA64 Extreme ver. 6.10.5200 is the only hardware monitoring application I'm using as I've read multiple monitoring apps can cause the ITE IT8665E Super IO chip to bug out. (Among 1000 other things, is this thing just garbage or what?)
I'm also using the Logitech LCD configuration in AIDA64 to display temperatures/clockspeeds/VRM current/power/etc. basically all the important information I can fit spread between 4 pages on my Logitech LCD. However, I'm not monitoring fan speeds on my LCD just in case that's causing an issue.
After anywhere from 15 minutes to 2 hours, the fans I have connected to motherboard headers will stop spinning. After doing some experimentation and attempting to control the fans after they have stopped, I've figured out that the fan logic is randomly inverting. That is, 100% fan speed becomes 0%, and 0% becomes 100%, 66% fan speed becomes 34% fan speed etc. So after it happens, I can set the fans to 0% and they will spin back up to 100%, or to 34% and they will spin back up to 66%. So I have some form of solution, albeit not an ideal one.
I've also noticed that once the logic reverse happens, the fan sensor values in AIDA64 either freeze at their reported value, or they just show 0 RPM depending on how it's feeling at that particular instance. If I'm not running AIDA64 this will not happen, but it's an inevitability whenever AIDA64 is running. Rebooting the PC or sleep/resume will correct the issue for another 15 minutes to 2 hours.
Here are the only options I have enabled in the stability section of AIDA64:
Load Kernel driver Low-Level MSR Low-Level PCI Low-Level SMBus Low-Level sensor Low-Level SMART SMBus access through ACPI GPU Sensor Support I have disabled Asus WMI sensor support because I read that can solve the issue, but it hasn't helped.
This is also the second fresh install of Windows 10 on this machine, and it has happened during both installs. I'm on the latest 5220 BIOS, and changing all of the parameters of Q-Fan in the BIOS doesn't seem to have any effect.

A few odd things. I've recently added cheap water cooling to my PC.
It might be a misunderstanding (or reconfiguration) on my pat.
1) Sometimes when I start the PC and AIDA64 auto starts, it only shows the 3 white fan options as shown in the bottom of pic "Turn on PC".
If I close AIDA64 and restart it, or reboot, it comes up with the 5 fans it should have (see bottom of pic "Restarted"),
2) very occasionally it starts correctly by showing the 5 fan options, but will say both the GPU Rad fan and the Temp Side Fan are 0 RPM even though they are spinning (sorry haven't got a pic for this)
Note, Power supply fan should be 0 RPM as it's a quite PS that only starts the fan if needed
3) With my CPU watercooler, I installed Corsairs iCUE fan control software (I presume this is needed to control the fans?). That software shows completely different CPU temps to yours. When running your Stress Test, (all in C)
After 40 seconds, yours says 39 , iCUE says 33.7
After 2 mins, yours says 40 iCUE says 34.3
After 3 mins yours says 40 iCUE says 34.8
After 4 mins yours says 41, iCUE says 35.1
After 6 mins yours says 41, iQUE says 35.6
After 11 mins yours says 42 iQUE says 36.1
Pics of the above attached. I left it running for a while longer, but the temp stayed fluctuating between 41/42.
Then after I'd stopped your stress test for a couple of mins or so your s/w says 29, iQUE says 34.6
