Not sure how LLMs failed me, please elaborate.
Also not sure how you found that model number, it's literally an F71878AD, here's proof:

I can show you a HWiNFO screenshot of it not reading anything off the SuperIO except Chassis Intrusion: https://imgur.com/a/dYPETWz
The only way I can get a temperature reading is off the CPU probe directly, which I am already making use of. As the article covers in later parts, I'm using HWiNFO and/or PawnIO to do exactly what you say (reading off the CPU probe sensor) and feed it into a fan curve, which then sends the appropriate duty cycle to the arduino.
In the BIOS there's no temperature reading, no fan speed display, and no PWM control whatsoever.
So maybe MSI did wire up the SuperIO, I can't say for sure, but they definitely didn't wire up something, otherwise the BIOS could at least control the fans or see their RPM.
And I've also tried with multiple BIOS versions, so it can't be BIOS related.
Some people online had working sensors on their MSI 970 boards, some didn't, leading me to believe it must've been a defective batch where they forgot something.
