Not at all. That is well within spec and well under TDP and/or TJ Max for the system.
I was worried as I could feel the temperature rise. It had been 10 days since I started using the device.(M2air)
That's why 44-46 degrees scared me.
🥱

80C is 176 degrees Fahrenheit, 100C would be 212F (the boiling point of water at sea level). Even 46C is 114.8F, so it would feel somewhat warm to the touch. Keep in mind that most Intel/AMD desktops will not throttle until you hit somewhere in the 95C-100C range, depending on the specific CPU being used and how cooling is set up.

Thank you 🙏🏻
I agree. Without going into the details of the pages you were on, if you happen to load a number of poorly performing pages, the resulting heat due to the load on the processor would be normal and within the specs of what the system can handle. However, as most folks likely don’t go to your exact number of tabs to the same sites that you go to, “normal” for THEM is a system that doesn’t get that hot. :)

Even with only 1 tab open from safari, it is a bad thing that it is 46-67 degrees and this temperature is felt. (For laptop)

m2 air hotter than the m1 air/pro :((
I opened the same tab in m1 and it was 35 degrees.

Oh thanks.When everything is closed in the background in the tg pro application or when you open youtube from safari, it is 44-46 degrees, is this normal? What does your tg pro look like?
Running YouTube in Safari is not very efficient and will use more power than running YouTube in the YT app.

The MBA will not hurt itself by running hot. If you really push it for longer than several minutes it might slow down a little to reduce the heat but it will never overheat to the point that any damage is done.

Thank you everyone.
I'm confused. Some said it's normal, some said it's not normal.🥹
That’s because you need no credentials to answer someone on Macrumors.

So with that in mind: it’s a totally normal reading.

No you can’t really compare temperature readings with an M1. Different chip, we don’t know if they’ve moved the sensor. Different case, different heatsink. One thing to measure which chip produces more heat in idle would be power consumption by the outlet, but the fact that the computer has a battery buffer would make that unreliable as well.

All we know is that M2 efficiency cores are notably better than M1 and that the ”omg hot” clickbait videos/articles at launch were all about high workload situations.

I understand that 44-46 degrees is normal for m2 air. It does not harm the laptop. But the temperature increase is a bad experience for the user.
M1 35 degrees.

I want someone who owns an m2 air to just turn on the device and send the test result via TG PRO.

well, depends ...
I guess that for example with this one it may get hot pretty quickly ;)

It’s normal, I had an M2 Air for some weeks and those temperatures are normal.

The reason the M1 is cooler, it’s because the M2 runs at a bit higher frequency. The M1 performance cores run at 3.20GHz, and the M2 performance cores run at 3.50GHz. The difference is even bigger for the efficiency cores.

So yeah, higher clocks, higher frequency, higher speed equals to higher temperatures. Anyways, both 35°C and 45°C are perfectly normal (I would even say cool) temps for a CPU. You should also know that while the M1 can reach up to 100°C, the M2 can reach up to 108°C, and again, that’s normal, those are the temperatures by design.

If you’re not happy with your MacBook Air you can return it, and wait for the M3 model next year, which will probably run cooler if it’s manufactured at 3nm.

Ohh thank you very much.

When I turned on the device, I was afraid to see these temperatures.(44-46)

After using it a little bit, it goes over 46. It sees 70-80 and drops again.

My M1 runs around 45 degrees with 80-90% idle. If 45 is making the laptop hot, it’s not normal. My M2 also has similar temp and isn’t warm/hot.
My friend has M1 air. He uses the device with a few tabs from safari. It's 30-35 degrees on average. That's why it's very nice to use. I wish the M2 air was that cold as well.

Unfortunately, the laptop is overheating and I can feel it. What should I say for a change from the service?

This is what I usually do, I don’t worry about outside noise/opinions. I evaluate all my laptops with in the return window.

1. Start using it like the main purpose you bought it for, same way as your real workflows. videos/YouTube/coding, browsing or email. What ever may be the main purpose of purchase.
2. Use it in places you would use, desk? Couch? Bed?
3. Evaluate the experience, too slow, hot?
4. Some fringe cases, I may encounter occasionally or just a stress test to see the limits.

If you think it’s too hot, return the laptop. No point being obsessed over numbers.

The smaller ~3nm process will allow more power for less heat. But we have no reason to believe that Apple will make the next generation run cooler than the already-excellent current generation. More likely is that Apple will reduce build/engineering costs and/or increase performance while staying in the same appropriate temp range that they are in now.

M1 35 degrees.
I had an M1 air and got an M2 air. My M1 idled around 35C, the M2 idles around 42C. I don’t notice any difference in case temperature so the temps impact my daily life in no way whatsoever.


Please..

I don’t have TG pro, but my M2 air runs between 42-46 for most tasks.

If you can feel the difference and the machine is too hot for you then return it and buy an m1 air. They’re cheaper anyway so you’ll save some money.

Stop worrying and just use your computer to get your work done. If you can’t get your work done with the machine then get one that works for you.

44-46C is nothing to be concerned about. Most systems can run between 80-90C without significant slowdowns, so there's more than enough thermal headroom left for you. Here's my temps running the M2 Max:

FWIW, those CPU temperature readings might not be correct. There's an known issue with the latest version of iStats wherein M2 Max/Pro CPU temperatures are displayed incorrectly under light system loads. The iStats developers seem to think that it's more of an SMC-related issue rather than an iStats-related one.

As a comparison, my M2 Max Mac Studio is currently hovering at ~40C under relatively light loads but it's still a bit out right now so it'd probably be a few degrees lower if I had the A/C on.

M1 35 degrees.

The M2 MBA will go up to 108 degrees if you stress it. And according to Apple this is fine.

So 44-46 degrees is nothing to worry about, it is fine.

The M1 chip runs cooler because the M2 chip is overclocked.

Something sounds off. Mine is a M2 MBP so I have no direct comparison, but the case was getting hot and uncomfortable sounds wrong for M2 SoC. I do not chase temp readings, just how it feels, and my M2 MBP never approaches anything like the case was getting hot and uncomfortable.

Even my 2016 MBP only gets somewhat hot if it is worked really hard, hard enough to force aggressive SSD swap, etc. due to the limitations of 16 GB RAM (max available in 2016). The M2 MBP has 96 GB RAM (max available in 2023).
Thats cos MBP has a fan and the Air doesn’t.

My M1 MBP gets hot enough to make me sweat through two blankets when using it on my lap in bed, getting the bottom of the Mac wet. I now only use it on a table, worry about water damage.

I actually have the MBA M2 16GB/1TB/10CoreGPU Model and with many Browser and Apps open an average of
1689510645868.png
37 Celsius
1689510601266.png
with Hot App when having 30 Celsius Room Temps.

As your MBA is New it may perform some more Tasks in the Background cause you have an average of 80% Unused CPU. The Temps look OK for 80% unused CPU/GPU.

I have also the MBA M2 in Clamshell mode and a Casing:
