Increased fan noise since updating to MacOs Monterey.

I have the same issue, and after the fans kick up, they stay full blast. I was watching a youtube video 5 minutes ago, and the fans are still full blast as I write this, and don't slow down. The computer is also getting hot, and it's killing the battery life. I want to downgrade!

I probably should have been more clear, apologies. The fans are not the problem, they're just doing their job. The Macbook Air is getting unusually hot for the task at hand, since upgrading to Monterey. Watching a youtube video after a few minutes now causes so much heat the fans are forced to run hard. This didn't seem to be the case before. I used this computer for a year, and never heard the fans kick up, except when editing in Final Cut. The fans also run for a long time after you quit out of the video. This computer is now so loud, I don't really want to use it. I'm not going to jump through a bunch of hoops to try and fix this. I don't have time, I'll likely wipe the drive, and install Big Sur again.

Same here… as soon as I Start my macbook air 2020 after the upgrade the fans are going full blast, doesn't matter if any app is on or not. Seems like the OS Monterey is built for the M1 processors and too heavy for the T2. Going to downgrade if I don't find any real solution in the next days.

I just downgraded to Big Sur, and the MacBook is happy again. I would note, however, that it appears to get just as hot as with Monterey, only without the excessive fans. It may be that Apple changed the fan profile for Monterey, trying to get the computer to run cooler. But whatever the reason for this, the fan noise was unacceptable.

Hello,

I also have a MacBook Air 2020 and my fans are still running excessively every time I use Chrome for any level of browsing or streaming video. It has not improved after the 12.1 update. In fact the fans start running even sooner.

I have restarted the laptop and rebooted Chrome repeatedly. And I use Activity Monitor to force quit out of the biggest CPU-challenging applications. The Window Server seems to be constantly taking up lots of CPU.

What else can I do? Wait for another update?

I don't want to use Safari because Chrome is optimized for everything I do every day.

Thank you for your help.

Hello Fonz93,

We're glad you thought to ask Apple Support Communities about the increased fan noise since upgrading to macOS Monterey. See if the steps in the following guide help: About fans and fan noise in your Apple product

In addition to the above, use Activity Monitor to see if any app or process is possibly using too many resources and causing this to happen: View CPU activity in Activity Monitor on Mac

I've done some troubleshooting, and found that firefox seems to be my culprit. I can stream 4k video in safari no problems, but watching the exact same video on Firefox causes much more heat, and the fans to kick up. As a test, I actually watched an entire 4k video in firefox, and the fans were full blast. I then loaded the same video into Safari, and watched it, and the fans eventually slowed down, even though I was still watching the same video. Not sure who to blame, but since it worked fine in O/S Big Sur, I'm gonna point the finger at apple.

Hello,

Obviously there an issue with the monterey update as i face the same issue from the second i updated this version. No issue related to the computer. I m thinking about downgrading as this Monterey seems to start with issues.

My Macbook Air has increased fan noise since updating to MacOs Monterey. I have established a case with Apple. They maintain that they have not heard this was an issue until today. I have tried all of the suggestions on this thread which have not worked. No hardware issues.

I've also experienced increased fan noise since updating to Monterey. Running Teams, Pulse Secure, and Microsoft Remote Desktop as I have done prior to upgrading generate increased fan noise. Even now while typing this message within Chrome the fan noise got even louder. My plan is to restore from a backup and roll back to Big Sur.

FYI: I'm running a MacBook Pro (Retina, 15 inch, Mid 2015), purchased in 2017.

I have had the same problem of excessive fan noise since installing Monterey with my 2020 MacBook Air. I sought help with Apple through chat then worked with an online tech who could not resolve the issue. They all did not recommend to roll back to Big Sur. They booked me an appointment with the Apple Store which wiped my computer and reinstalled Monterey. I pulled in only current files from my time machine and still the fan would go on once it went to sleep. One thing the Apple store tech told me is that Chrome can make a computer run hot. I reinstalled Chrome but am making Safari my main browser-no more fan noise (so far).

Since this is a software issue that happened after the most recent IOS upgrade I contacted Apple and we went through all of the steps to determine the issue-they couldn't find the source of the problem but recommended that I do a clean install of Monterey at the Apple store. I went to the Apple store where they wiped my computer and reinstalled Monterey-this didn't help once I started working in Chrome. I deleted Chrome and reinstalled it. This seemed to work for me.
