@Ramp Max tech has made videos over the past few days showing the macbook air reaching 108 degrees C. This was for cpu workloads at full power for 23 seconds. This boi heats up fast. running cinebench for 23 seconds brought the temps up to 108, the chip then thottles by reducing its power output from 17watts down to 9 but it maintains a clock speed of 2.45GHZ. this is far from the 3.5 that it normally targets but its not bad for a fanless laptop with no heatsink. The gpu is a totally different story especially on the 8 core model. The chip maxes out at 77 degrees C on a full GPU worload (3d mark for 1 minute.) Unfortunely after 5 minutes, the chip will hit 108 degrees C and start throttling. BUT THERES A FIX!!!!! opening the laptop and adding cheap thermal pads from amazon will use the back plate as a heat sink. this means the CPU will take 4 mins to throttle as opposed to 23 seconds and the gpu can run full power for 9 minutes compared to 5 minutes without the heat pads. anyway. this laptop is not designed for sustained loads. people who buy this computer will use it for light every day tasks which is why the single core score is so good. if someone needs sustained loads from their laptop, they need a pro, not the air.
@Ramp It doesn't matter what "typical use" is when it comes to hardware design choices such as these. What matters is what the machine is capable of doing. There will always be users who push any given machine to its full capabilities. What the OP suggests is a perfectly plausible (and testable) guess. Overheating is overheating, regardless of what the chip inside is. The M2 has been shown to reach temps above the boiling point of water, so yes this would absolutely be a welcomed quality of life feature for some users.

The accelerator is used for spatial audio mapping. So if you turn the laptop and your head at the same time, the sound will stay pinned at the same place. It's definitely not used for Find My as mentioned here

Probably because most base 256gb buyers wouldn't notice and they need 128gb modules from their iphones and ipads, the chip shortage might have to do something with it.
Great teardown! I'm not surprised there's no heatsink anymore. Apple could tremendously improve their sustained performance in iOS devices, yet they choose not to use any heat spreaders. The M2 MacBook Air is just following that trend
The issue with adding a heat spreader is it migh transmit heat to the the bottom case. And there are very strict regulations as to how hot it is permitted to get. Without active cooling if there is a good path for heat to hot the bottom case the cpu might need to throttle down at temps of just 50c to ensure the bottom does not heat up to much or they would need temp sensors attached to the bottom case making removing it much harder!

some youtubers have gotten better benchmark scores by adding a few strips of thermal pads to spread the heat. eventually the whole inside gets hot though and throttling still occurs. If someone comes out with a proper heat sink/thermal kit with a replacement vented case bottom i’ll be first in line to buy one.
The however thin metal logic board cover is the "heat spreader" - since there's no direct contact/vent way to take the heat out, it only saturates air pockets till it cools down radiating heat through the outside shell, there's probably no need for "more effective" spread of the heat inside in the small space there is anyway. The Air cooling is not about getting the heat out conventional way, but managing the chip usage based on the trapped air temp inside. I just wish Apple incorporated some partial heat transfer method to the back, not full hot thermal mod like option (which I don't mind on the M1 Air), but some partial spread with less but some conductivity.
Any attempt to use the bottle of the Mac risks it getting too hot (there are strict regulation limits on how hot it can get to avoid burning people). Would would be amazing is if they figured out a way to channel the heat to the back of the monitor if the panel can take that heat that is.
This very idea of moding with a copper sheet and thermal paste also crossed my mind. Although the space is constrained, I believe it is enough to accomodate these.
Would that really improve anything? The problem isn’t extracting the heat from the chip. The problem is that the chip generates too much heat for the tiny metal body to handle while staying under 50°C. That thin heat spreader already does the job of spreading the heat away from the chip, but the heat stays within the frame. It’s trapped. Adding a larger heatsink won’t change that. Just my thoughts. Adding thermal paste will transfer the heat towords the bottom panel wich will make it hot to touch. Which isn’t good for men’s fertility if you put it on your lap. It really doesn’t get hot with conventional use, only under extended heavy load will it throttle, which is what it is supposed to do to prevent overheating. The next M3 will be better since it will be based on 3nm and generate less heat.
I would love to see temp values from any sensors in there. That is such a neat assembly - if i hadnt already got a book - this would be the one of choice
Do you think it the heat spreader is good enough to not cause internal damage in the long run? For someone hoping to use this laptop for approx 8 years
not related much video but only now I've realized why the M1 is so good and at an aggressive price; not much apps available at launch and Apple wanted enough people to get it so apps get made for the M1. The M2 doesn't look so hot vs AMD/Intel and with a huge price increase.
@@orangefiltersky9387 Apple haven increased the IPhone price since the iPhone X. They're pretty consistent. They even dropped the price when iPhone 11 came out.
@@kavink2514 like he said, most youtubers are just sticking some thermal pads to allow heat transfer to the bottom chassis, which helps but will likely be hotter than the safe temperature for skin contact (>45C) I'm asking more about just adding more thermal mass to the 'heatsink' so that it absorbs more heat before throttling, given how we see there is some empty and underutilized space next to the logic board.
I had no issue replacing HD on my old macbook pros from 10 years ago but it looks like it would be a real pain in this laptop - this drive to be uber thin - and wondering about heat - makes this machine a pass for me
You can drastically improve the thermal performance by adding more thermal conductive mass with copper shielding tape. Remove the graphite tape from the metal shielding panel, apply copper shielding tape on the metal shielding panel, but don’t cover over cutout areas. You basically just want to add more conductive thermal mass to the existing metal shielding panel. Do not cover over cutout areas because you don’t want heat transferring over from the CPU to these chips. Now put back the black graphite tape over the copper. Make sure not to add copper tape to the area where the trackpad ribbon cable is routed! Now you have a proper heatsink!! This solution does the job without causing heat to get transferred to other critical components, using thermal pads will raise the temperature of your memory and storage!! You can also buy another bottom case cover and drill tiny ventilation holes to allow hot air to escape! Use a tiny dremel drill bit with a printed hole guide to make it look clean and professional 😂 FU Apple!
Accelerometer could be for future device security/alarm support, apple analytics on device usage patterns, webcam video stabilization, vibration/impact tracking for warranty???
great video! What's the best way to open the bottom without damaging it? I'm nervous that when I open it I'm going to break the clips. Any tips or ticks will be appreciated. Thanks!
Usually the accelerometers in laptops protect hard drives from damage. If the laptop were to suddenly drop while in use, the accelerometer would detect the sudden free fall and immediately turn off the hard drive to avoid hitting the reading heads into the hard drive platter. In this case, I have no idea why since it has SSD
I think MacBooks always were with accelerometer, my 2009 MacBook Pro had one and there were some apps that used them, I remember seismograph app and one of this iPhone like games with a ball in a maze.
In older computers those sensors were used to detect drops so the hard drive would stop spinning to prevent data loss/corruption. In newer macbooks with SSDs, those sensors were omitted.
I came here for details on how to get the inside clips off, but both you and @maxtechofficial just glossed over that as if it weren't terrifying to get right
I'm a bit curious about the heatspreader, does this has less thermal capacity compared to the previous gen M1 Air? Looks like M2 chip on the Macbook Air is quite toasty, and M2 seems to pull slightly more power during heavy load too.
Yes this has less thermal capacity than the M1. MaxTech and some others have done tests and this thing gets really hot when doing anything demanding - hitting 108 C before throttling down. Looks like Apple is letting these chips run hot.
Most likely yes, since there's physically less or nothing to transfer heat away. M2 actually draws significantly more power, since it's an overclocked M1 with even more graphics cores. The graphics in my binned M1 pull half as much power as the 10-core M2.
Drop detention. Apple diagnostics are able to report back if the device has been dropped in the past. So even if you have a case and there's no external damage, they can void your warranty anyway if they see you dropped it.
M.2 drives do not require heatsinks. Only the controller chip benefits from the heatsink, not the NAND. NAND retains data more effectively when it's toasty.
the accelerometer helps detect falls - in older machines, it would retract the hard drive heads on mechanical hard drives to avoid the head crash during a fall. i imagine it is used to avoid some similar mishap when it detects that the machine is falling. 🤷 nice to see the modular ports - this makes the most commonly failing component - the plugs more repairable, and you dont have to get a new motherboard if all that failed was the user busting their usb plug.
Some macbooks with hard disk drives had an accelerometer for stopping the disk when it gets dropped to protect the data. Maybe this is so apple can read out if the machine has ever been dropped when doing repairs so they can know if warranty applies or not
M1/2 Macs have no way to persist that data in such a way that it cant be clerked very easily (we know this from the linux on M1/2 team). There is some read only data but everything else can be reset with a DFU mode so would not make any sense to do that.
I've noticed 13" M1 MacBooks wake when moved, which is literally the only accelerometer use I've found. Maybe it's also used in warranty evaluations to check if it has been dropped?
Apple could've done the right thing and not "sabotaged" the SSD speed on the base model. So the M2 Air won't perform well without paying additional premium for 16gb ram AND the faster 512gb memory, the latter something most people likely won't need anyways, or can anyone argue that merely adding the extra RAM will suffice to perfom well?
They haven’t. They only make 256 SSD now. They aren’t going to put 2 x 128 in there to just increase the speed. And anyone buying the base model wouldn’t even care let alone notice.
The 16 gb ram will suffice. There is a youtuber that did the test. The 16gb ram is the determining factor for performance with the M2. It increases the performance of the chip. Only when you work with or transfer very large files then the ssd becomes more important for performance.

Can you guys Teardown The Nothing Phone (1)? I would like to see inside of The Phone. thank you!
Thank you man for sharing this stuff
Where's the score?
Any idea why they left half of the logic board empty? It should be used for better heat dissipation or something.
2:19 there's another board next to it that's connected to audio, so it's not just empty space
Perfect video! love the envelope! 😀
So, i assumed that you can change a battery on this model too?
Now I'm wondering if someone would try modding the heatspreader by adding more mass to it? Making it similar to the one in the M1 air
Luke Maini already did that I belive.
@@kavink2514 that's just pasting some thermal pads. would be nice if there is a third party heat spreader for us to mod once warranty runs out.
@@kavink2514 like he said, most youtubers are just sticking some thermal pads to allow heat transfer to the bottom chassis, which helps but will likely be hotter than the safe temperature for skin contact (>45C)
I'm asking more about just adding more thermal mass to the 'heatsink' so that it absorbs more heat before throttling, given how we see there is some empty and underutilized space next to the logic board.
really cool teardown 👍
I would assume the accelerometer is to shut down the device if it is dropped? I have no idea.
Accelerometer to detect whether the damage was due to falling!? Maybe
Please do an iFixit version of heatspreader fix/mod. People will want to buy those.
I still love my 2020 M1 mbp it's a beast, no matter how many streams of 4k60HDR I throw at it I can't seem to bog it down
Impressive
The sibilance in the video's sound is horrendous.
If someone makes a third party heat sink to replace those heat spreaders it might be cooler
I had no issue replacing HD on my old macbook pros from 10 years ago but it looks like it would be a real pain in this laptop - this drive to be uber thin - and wondering about heat - makes this machine a pass for me
The air solders their hdd/ssd
The accelerometer could be used to detect drops and falls, maybe for warranty purposes?
No since you can clear all writable storage using the DFU mode so would not make any sense.
You can drastically improve the thermal performance by adding more thermal conductive mass with copper shielding tape. Remove the graphite tape from the metal shielding panel, apply copper shielding tape on the metal shielding panel, but don’t cover over cutout areas. You basically just want to add more conductive thermal mass to the existing metal shielding panel. Do not cover over cutout areas because you don’t want heat transferring over from the CPU to these chips. Now put back the black graphite tape over the copper. Make sure not to add copper tape to the area where the trackpad ribbon cable is routed! Now you have a proper heatsink!! This solution does the job without causing heat to get transferred to other critical components, using thermal pads will raise the temperature of your memory and storage!! You can also buy another bottom case cover and drill tiny ventilation holes to allow hot air to escape! Use a tiny dremel drill bit with a printed hole guide to make it look clean and professional 😂 FU Apple!
Accelerometer could be for future device security/alarm support, apple analytics on device usage patterns, webcam video stabilization, vibration/impact tracking for warranty???
great video! What's the best way to open the bottom without damaging it? I'm nervous that when I open it I'm going to break the clips.
Any tips or ticks will be appreciated.
Thanks!
great video as always
Great video
Usually the accelerometers in laptops protect hard drives from damage. If the laptop were to suddenly drop while in use, the accelerometer would detect the sudden free fall and immediately turn off the hard drive to avoid hitting the reading heads into the hard drive platter.
In this case, I have no idea why since it has SSD
Excellent ... well done ...
is it possible to remove each key at the keyboard seperate to clean it underneath?
@iFixit. sammerino no thanks xd
Accelerometer is for spatial audio with airpods
Sound editing, please! The sibilants are killing me.
So if I decide to put heat shrink padding where would it go?
I think MacBooks always were with accelerometer, my 2009 MacBook Pro had one and there were some apps that used them, I remember seismograph app and one of this iPhone like games with a ball in a maze.
In older computers those sensors were used to detect drops so the hard drive would stop spinning to prevent data loss/corruption. In newer macbooks with SSDs, those sensors were omitted.
@@maybethisismarq yes sure, but the sensor was available for developers as well, so it was not used just for that
I came here for details on how to get the inside clips off, but both you and @maxtechofficial just glossed over that as if it weren't terrifying to get right
Im betting they have the accelerometer to be able to see if you dropped it or exposed it to excess vibration and denie your warranty claim.
I'm a bit curious about the heatspreader, does this has less thermal capacity compared to the previous gen M1 Air?
Looks like M2 chip on the Macbook Air is quite toasty, and M2 seems to pull slightly more power during heavy load too.
Yes this has less thermal capacity than the M1. MaxTech and some others have done tests and this thing gets really hot when doing anything demanding - hitting 108 C before throttling down. Looks like Apple is letting these chips run hot.
Most likely yes, since there's physically less or nothing to transfer heat away. M2 actually draws significantly more power, since it's an overclocked M1 with even more graphics cores. The graphics in my binned M1 pull half as much power as the 10-core M2.
The m2 logic board in air has a gyroscope chip. Maybe they might fit the same logic board in the m2 ipad pro🤔
1:04 I feel bad for that copper tab
This is a masterpiece, so fun to watch!
Accelerometer to know if someone dropped the laptop?
2008 original MacBook Airs had poor cooling too. Deja vu.
Eita. Obrigado
would love some high contrast creatice electron images of those boards especially the wireless hybrid modules
no repair score?
Drop detention. Apple diagnostics are able to report back if the device has been dropped in the past. So even if you have a case and there's no external damage, they can void your warranty anyway if they see you dropped it.
The right direction. But old devices suffer.
Awesome & Thanks :)
M.2 drives do not require heatsinks. Only the controller chip benefits from the heatsink, not the NAND. NAND retains data more effectively when it's toasty.
Apple's new CPU is called the M2. Yep, it's confusing. This machine has an M2 processor and M.2 storage.
great video!
Avatar was rendered on a M2 Macbook Air, it does just fine without active cooling.
Can't wait to see apple gluing their laptops like they glue their phones and make everything non replacable by pairing each part with serial numbers.
Why would they be selling parts then?
beautiful engineering !
the accelerometer helps detect falls - in older machines, it would retract the hard drive heads on mechanical hard drives to avoid the head crash during a fall. i imagine it is used to avoid some similar mishap when it detects that the machine is falling. 🤷
nice to see the modular ports - this makes the most commonly failing component - the plugs more repairable, and you dont have to get a new motherboard if all that failed was the user busting their usb plug.
Where’s the repairability score? 🤔
Drops and Falls was why Macs had accelerometers before maybe the retina ones… There’s an app to test the accelerometer bundled with “OS X” 😅
Some macbooks with hard disk drives had an accelerometer for stopping the disk when it gets dropped to protect the data. Maybe this is so apple can read out if the machine has ever been dropped when doing repairs so they can know if warranty applies or not
M1/2 Macs have no way to persist that data in such a way that it cant be clerked very easily (we know this from the linux on M1/2 team). There is some read only data but everything else can be reset with a DFU mode so would not make any sense to do that.
@@hishnash even if it can be deleted the average user would either not know about the feature or couldn't clear it themselves
@@Shadow__X but if your repair is refused and you then go online you would find a tutorial on how to do it (it's very easy).
@@hishnash if apple refuses once they won't let a previously refused serial number though just because the error code is gone
I've noticed 13" M1 MacBooks wake when moved, which is literally the only accelerometer use I've found. Maybe it's also used in warranty evaluations to check if it has been dropped?
Interesting
Look at the inside of the bottom panel
Apple could've done the right thing and not "sabotaged" the SSD speed on the base model. So the M2 Air won't perform well without paying additional premium for 16gb ram AND the faster 512gb memory, the latter something most people likely won't need anyways, or can anyone argue that merely adding the extra RAM will suffice to perfom well?
They haven’t. They only make 256 SSD now. They aren’t going to put 2 x 128 in there to just increase the speed. And anyone buying the base model wouldn’t even care let alone notice.
@@danielbass09MANY PEOPLE CARE AND NOTICE over a 50% performance drop going from a 2 years old $999 product to a $1199 brand new one.
The 16 gb ram will suffice. There is a youtuber that did the test. The 16gb ram is the determining factor for performance with the M2. It increases the performance of the chip. Only when you work with or transfer very large files then the ssd becomes more important for performance.
Seems soon we will find someone making a heatsink upgrade kit for the M2 MacBook Air.
