M2 fanless heat issue

Max Tech is clickbait garbage. You would do wise to avoid his crap.
i liked your comment because it's true and fair
that said while the conclusions they make isnt very objective,their tests are .they test and compare in a fair way ,and they dont cheat do they? the temps are indeed higher.the performance isnt impressive for many tasks.and ssd speeds are **** ,they're not the only ones talkin bout it .
apple is using one single nand chip isntead of 2 hence the lower speeds compared to m1's double nand
can't believe apple's cheaping out that way when they increased mbp m2 by 150 euros in france and europe ,compared ot mbp m1 . m1 was 1450 euros, but m2 mbp is 1600 . crazy ain't it
The testing seems fair I will give him that much. I don't like his primary modus operandi with his videos albeit he isn't the only clickbait artist not being truly honest and objective in videos, so that he can manipulate the audience for YT gain.
Bench testing and the like is worthless in my tech book. What matters to me, is how does a particular device function for the customer who bough the device on a day to day basis, not what alarmist, clickbait junkies looking for more revenue think. Max tech is one of the worst about sounding the alarm bells and trying to make a point of two the worst, when it really isn't.
Isn’t the performance per watt better on the M2? So with a workload that is below 100% CPU utilisation of the M1 (being the slower chip), the M2 should actually run cooler? And at 100% M1 CPU utilisation (and higher for M2), the M2 may run warmer, but that’s only when it is exceeding what an M1 can do, so may finish the task before throttling.
Wow - if this is really how the "new" M2 MBP is running, this is an embarrassment to Apple.
yep and mind you,i prefer a clickbait youtuber who still gives me torough test and detailed videos ,over a non-clickbaiter like mkbhd whose success i cannot comprehend . dude barely scratches the surface,how is he so successful and popular .anyway i digress .
yeah but in the end of the day ,ssd speeds are ssd speeds,and temperature is temp,that u can't deny.macOS will make it feel smooth but refusing to aknowledge these problems is folly ,and you'll likely experince worse swap,as well as slower transfer speeds .that said i get your point ,and i agree ,this clickbait is just very annoying to live with ,which is why i unsub from their channel
yeah you'd think so but it looks like it isnt,as many test show 13% perf improvements with about 30% power increase lol
also the chip is much hotter at idle . 29 degrees vs 37 . so yeah
I’m wondering the same thing about the throttling. I do believe the M2 draws more wattage (maybe it’s only the GPU cores that do? but still). More power draw = more heat. Had they slapped the M2 in the same M1 chassis, I do believe we’d see greater throttling than we see with the M1. Having said that, like another poster mentioned, we’re seeing better IPC on the M2 CPU so maybe that would cancel out the performance loss from throttling.
However, the M2 Air is a completely new chassis. I’m hoping they beefed up the heat sink to combat the theoretical higher heat output. Guess we’ll find out in a month!

Mmm… I don’t think they cheat, but sometimes their gut is wrong on things or there are circumstances that will be resolved etc. they do throw stuff out there obviously for clicks but they are having a crack. I will give them that.
Please avoid this channel like the plague.
no one has the new air yet, but already ppl are warning about the midnight finish and fingerprints, heat issues... what else?
it's always good to judge something in advance of anyone actually experiencing the actual thing. 🙃

I heard it has a notch...
They're just disingenuous. They don't outright lie, but they do and say whatever they can in order to get clicks. They'll go and compare the performance between the M1 iPad Pro and A14 iPad Air 4, then a year later they'll compare the iPad Air 4 and 5 and do the same tests on the same chips and get the same results and act all surprised.
Or Apple puts keyboard and mouse gaming APIs into iPadOS, and one game comes out supporting it and they make a "RIP PC Gaming!" video - two years later it's still pretty much the only game on the iPad with full keyboard and mouse support and PC gaming is in exactly the same position.
The list goes on.
Well I taking a comparison of the m2 in the MacBook Pro which has a fan and appears to get quit hot so my question was how much more in a fan less laptop will it be. Im not as worried about finger prints but people are going off what people said who did in fact touch I believe
No one has reviewed an M2 MacBook Air yet. All this speculation is based only on the fact that the pro with the old Intel design still has a fan. No one knows how it will perform vs the new MacBook Air’s passive cooling system designed for the M2. There’s reason for a lot of hope here given what Apple Silicon has been able to do for silent computer operations in the old casings.
Guaranteed the M2 MBA will be throttled by power delivery, thermals, or both.
The throttling is by design. With the M1 MBA, Apple deliberately removed the fan to limit performance. They didn't even put fins on the heat spreader. There is no way M2 MBA will avoid heavy throttling, given it's the same thickness.
M2 CPU = 19W
M1 CPU = 15W
Even if thermals were not an issue, the MBP has a more robust VRM compared to MBA. To deliver the same clock speed at the same high temps requires higher power delivery.
The 1x256GB SSD speed issue is a matter of cost reduction, plain and simple.

If the thing is the storage speed is true, I’m wondering how this will affect on memory pressure scenarios, when ssd speed makes the difference. Half the speed is quite noticeable !!
I'm sure Apple has thought this through for the new MBA. They're not just going to increase the cores clock speed, the number of cores and die size without considering the additional thermal output.
Exactly, the new Mba will perform better than the M1 because of the larger cache, more bandwidth and more cores
They will keep the same core speed
I find it interesting how all these guys seem to already know how the MBA will perform based on the M2 chip in the old MBP chassis. I will assume that Apple has taken into account that the M2 chip runs a bit hotter, which might be part of the reason for the new design. Let's just wait and see, instead of jumping to conclusions based on those clickbait videos. Clickbait is just that, everything is made in such a way that they get as many views as possible.
Apple gave a very interesting presentation at ISSCC in February, you can watch it here:
Apple at ISSCC
The main point is that Apple Silicon chips are designed to vary their voltage, power consumption, clock speed, heat, etc depending on the application. Throttling is not a bad thing, it's a key part of Apple Silicon's success. At any given time only a fraction of the chip's 20 billion transistors are in use. The fact that M2's peak power draw is higher than M1's, doesn't mean it will produce more heat in day-to-day use. Only when the application requires it, M2 is allowed, and capable, of drawing more power.

You could use use a cooling pad with fans in it. I used to use one of those for my intel mac. Though I don't expect you'll need one.
get 2 fans from jet engines, weld the air onto your desk. then one fan on either side, and... get to work.
