CPU is getting warm after monterey update 12.2.1

1 - Suggest restarting in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

2 - Does the issue present in this mode ?

3 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

4 - If the issue is present in the dummy account - then this appears to be a System Wide issue.

5 - Suggest downloading the Application Etrecheck directly from a well Respected ASC Contributor. And Safe to use.

The application is free or paid from added features. 

Run the application with Full Disc Access ( Security & Privacy - Full Disc Access ).

It will take a Snap Shot -  both the hardware and software.

 The Report will Not Reveal Any Personal Information.

The User ( you ) can use a Browser similar to Google Chrome without the Helper Application installed with Google Chrome

The kernel_host is controlling all other processes of the operating system, so it will reside near the top of the activity manager CPU column. As was stated, you don't have a fan in that M1 Air to help expel the heat, so that unit needs to be on a hard surface that can radiate heat away from it.

Regardless of what browser you use other than Chrome, each opened tab (or window) is additional processes that require more CPU demand and hence, more heat.

Even if you were not running any third-party applications, Monterey introduces new features that were not present in Big Sur and there is a price to be had in increased operating system processes and additional threads associated with those processes. That alone means more heat for a fanless M1 Air.

Same app. TG Pro. Never been near to 24. That is crazy!

FWIW, I don't use Chrome but I suspect you may have something else installed that is driving the temp up.

Install EtreCheck and post the report. Allow Full Disk Access.

I have the same problem since "upgrading" to Monterey. MacBook Pro 2018, 16 GB RAM, 1 TB drive.

I used TG-Pro to create my own fan curve and let TG-Pro ran the fans. Works fine, most of the time. Monterey wants to run the fans at 6,000+ RPM all the time.

Like other users, I am doing nothing that would or should stress the CPU. But there is nothing I can do when the CPU load spokes and triggers Core Duet, that launches Kernel-Task and starts to throttle my machine. Audio gets choppy, video freezes, keyboard stops responding, meanwhile the temperature sensors are all nominal. If I could fund a way to remove or disable kernel-task, my machine would likely actually run cool and quiet.

Everything worked great under Big Sur, and I am so sorry I upgraded to an OS that is designed to use low heat, no fans, M-1 processors.

Well, I don't have an M-1, I have Intel processors for the foreseeable future. Either my hardware is broken or Apple's software is broken.

So far, I have read all the well-meaning advice, and none of it is a bit useful. There is nothing wrong with your SMC, nothing wrong with your fans, third-party apps are not the problem either.

Firefox may be part of the problem as with all its compartments and fences, it uses a ton of CPU.

Something unknown is loading the CPU but not raising the temperatures high enough on any sensor. The computer thinks it is overheating and seeks to throttle itself when, in fact, everything is running within Intel's chip specification for temperature.

BTW, the Built-In Security is NOT all that is needed. The built-in security doesn't stop ads.

Well if its bothering you with how hot your cpu is getting after the Monterey update I would check which apps start at login because the MacBook Air 2020 unfortunately doesn't have a fan.

Can I ask, which browser are you using for surfing?

What app are you using to monitor the temp? Using TG Pro my M1 MacBook Air is averaging about 24°C and that's while sitting on a carpet.
