MacOS 14.7 not letting manually control fans' speed

My 2020 M1 mini at work is on 14.7 and I can control the fan speeds with Macs Fan Control.
I can test my 2022 Studio when I get home.

I have M3 Pro MacBook Pro and nothing. I have even reinstalled Sonoma yesterday and that didn't help.
You can also read about this issue here at Github.
My experience was the following.
I bought Macbook M3Pro and with Migr.Assistant I have transfered all data from my Mac Mini M2 Pro.
Also, I have noticed, that sometimes when I have launched Boost Mode in MacFan Control, suddenly all fans stopped for about 30sec and then Boos Mode turns again. At that time I had no idea, that it's a rather unique sitation - to be able to control two fans manually on M3 Pro.
Just because I had M2 Pro before I was able to control two fans of my M3pro Mac Book. It looks like some system data from M2 - didn't let M3 Pro to disable fan control totally.
In September I made a mistake and updated to Sequoia OS. Now fans are dead up to 90C.
Of course, I have downloaded Sonoma 14 (not compatible), Sonoma 14.2 and Sonoma 14.4 and I have installed all these trying to run Mac Fan Control app, but nothing worked.
Mac Fan Control or other apps will work only with M2 (and probably M2 pro) CPU. As for M3, M3 Pro Apple just disabled access of any apps to fans. And with M3, M3 Pro its not possible to install Ventura OS.
Basically, Apple wants it gear to be silent and to throttle

This is unfortunate. Does anyone know if this break extends back to Intel-based systems as well (is it broken from 14.7 forward or just with certain hardware or just after certain firmware/etc updates)?
My situation is that I find that macOS does not ramp up the fans on my Mac Mini 2018 until it gets very hot but on the flip side thermal throttles the CPU much earlier than that. The thing is the fans are so good (i.e. quiet) that I barely notice them in my environment even when they are spinning at full throttle. However, the thermal throttling can be particularly annoying when I am trying to performance tune code or similar. Also when I leave programs running for hours/days at a time, maybe not such a great idea for the system to test itself against max temperature.
The trade-off between fan noise and thermal throttling may vary by environment and user. This is why it is nice to have the option for the user to control rather than assuming every user has the same preference.
I was able to control both fans in my M3 Pro MacBook Pro however I liked with iStats.You can also read about this issue here at Github.

It was working before I updated to Sonoma 14.7
Apple either broke something with Sonoma 14.7 and Sequoia or they're doing that on purpose.
I liked to run fans constantly at around 2500-3000 rpms when it was summer and really hot outside so the CPU and battery weren't in high temperatures but it's impossible to do now. I'm really considering to downgrading to 14.6
Well, I used to have Mac Mini M1 and later on Mac Mini M2 Pro.
Once I have discovered that both of them don't launch fans after 65C I realized that it is a built in by Apple throttling feature. From that moment I start using Mac Fan Control - setting cooler to 3400RPM and thats basically it.
But not anymore - thanks to apple
Now I have a feeling like to sell M3 Pro, and get M2 Pro + Ventura and good bye to apple's updates.

Wait I just read that you updated to Sequoia and then downgraded. Some people also say that they downgraded and they can't control fans up until CPU gets into high temperatures.
So looks like Apple did something on purpose with Sonoma 14.7 and Sequoia that even when you downgrade to older MacOS versions you are not able to control fans when they're off.
And they're doing that like 2 months before M4 MacBooks release lmao
This company has been a joke lately
If so it is likely the change wasn't Sonoma 14.7 specifically but the firmware (BridgeOS, etc) bundled with it. If so two things:
1. Issue/new limitation could get backported to older OS like Ventura (as well as, it is possible to install new BridgeOS without updating the OS for those who manually manage their computers)
2. It may be possible to avoid the firmware update and/or roll it back (i.e. though I believe the latter is a complicated process involving a 2nd computer and Apple Configurator) while still updating the rest of the OS
After I got burned by a seemingly minor Mojave update that included a BridgeOS update that caused frequent crashes on my Mac Mini 2018, I've become much more apprehensive about these firmware updates. I think that was 4 years ago and I am still bitter. Not the least because not only did it mess my computer up, I couldn't rollback and it took Apple like 9 months to release a fix.
If this is caused by the firmware, it's just another data point that Apple's approach to updating the firmware every single OS update is flawed. Especially if it was unintentional. Or if it was intentional, they should have included a release note to the effect.
