Temp Sensor problem with M2 Air

[Alex Cai]

I'm running Cinebench with Low power mode off, macsfancontrol updated to the newest version
There were no sensors such as Cpu core 1 98C showing up
Is that happening to every user or there is a bug

The sensors are all different on the M2. Macs Fan Control probably needs to be updated specifically for the M2. Contact the developer.

I've been playing around with the sensors for a week or so. The temperatures seem to be very different from the M1. The M1 had most of them nicely labeled and you figure out which ones were for performance cores, efficiency cores, GPU etc. None of that is obvious with the M2.

Take anyone reporting temperatures with the M2 with a large grain of salt for now. It is likely that the temperatures don't mean the same thing as with the M1.

Why are you trying to run Macs Fan Control on an M2 MacBook Air?? It has no fans to control or report on.

That isn't a problem with the M2. Your problem is the apps you are using, and whatever it is you are trying to do.

The Air has no fans. If it's reaching such temperatures is because you are running the chip t max on a passively cooled laptop.

My previous point is that the temp sensors on the app is not working properly

I tried istatisca and it worked
some cpu cores are missing but at least the temperature seems all right

So I just wait for the dev to update their apps

Just checking the temp of the battery and processor

Download the app called Stats. Compare it with your app.

Yes.

That doesn't look right, the palm rest could not possibly be 68C, that's above the legal limit for heat on surface of laptop.

I think Apple reused some of the SMC keys for different sensors in the M2. Most likely any label is not accurate for the M2.

I’ve read the current issues with a couple of open source projects on GitHub and there is no real consensus on what the sensors mean yet. It’s possible that the closed source commercial products are further along but maybe not. Apple didn’t make it easy.
