Detailed description:
Suddenly my fans are spinning at 100%. The device woke up from sleep and started cranking and GPU temperature is at 41 deg CPU at 1% usage. How do I stop it? How do I fix it?

So you mean
first you are on DC mode, then the battery drop to low power state,
then you put the laptop to sleep mode,
then you plug in the adapter, and wake up the laptop.
You see the power mode changed? This seems pretty normal.
And then the fan is running fast or a long time, this seems pretty normal too.
Did I misunderstand anything?
Thank you.

The battery did not drop to a low power state, I never said that? Is it normal for the fan to run at full speed for hours at a time when CPU is at 2% usage and the discrete GPU is disabled?

Hi there,
Would you mind to record a video of the whole process? It really difficult to understand by your wording.
How did you know the fan is at full speed? which program are you using for detection?
Thank you very much.

I have the same problem, it happens after waking from sleep, and, the same as in OP's case, MyASUS doesn't recognize any error. Laptop ZenBook 14 Q407, Windows 10 20H2 update.
