Weird behavior for AIO Fans and pump. Not sure what the issue is or if its fixable.

FanControl seems to be having recent issues maintaining control over the AIO Fans and Pump. Its behaving like it is controlling it for a bit, and sticking to the assigned curve, but then it jumps back to some arbitrary speed percentage causing the fans to ramp suddenly up. Super annoying to be sitting here with stable temps and the fans are constantly ramping up and down. I've been using Fan control since November maybe and havent noticed this problem until the last couple of weeks.

Searches for the same issue have proposed fixes by updating FanControl (did that, at the most up to date version), rolling back fan control (tried that, went back to 243 i believe, didnt work), checking Windows Defender (app monitoring is Off), checking BIOS settings (turned Smart Control on and Off, MSI B850). When that little question mark pops up, it shows a list of reasons why the fans may not be responding to the curve, and there is an option to Force Apply, but that doesn't even work. CPU temps are usually nominally around 50C, so I doubt there's any hardware overrides happening if it thinks its overheating.

Not sure what else to try at this point. Pretty close to just saying screw it and and setting it to manual mode.
