I just got the new MacBook Air M4, and I have noticed that it reaches higher temperatures than my old M2 MacBook Air. It goes up to 70℃ or more with very light usage, such as having a few tabs open and a couple of folders, while the room temperature is around 20℃ and the device is in an open area with good airflow. I’m wondering if this is an issue with the new M4 chip.

Exactly how are you measuring the temperature?
The best native measurement I can find without installing a third party app is a command that you run in the Terminal app. The command is "sudo powermetrics -s thermal -n 1".
I get the result Nominal and the full set of answers is Nominal, Fair, Serious or Critical.
I've the same issue with my M4 13"
Others have discovered that the message app consumes a lot of cpu and causes the air to run hot. Check the usage in activity monitor, kill the message process and see if anything changes
An application named HOT Download it from the web. Search for HOT for Mac; it will have a fire 🔥 logo.
Why does my MacBook Air M4 heat up so quickly?
