The fans on my 2015 rMBP rarely turn on either, simply because Apple didn't gimp the cooling on them like the later models. Intel doesn't run as hot as people think, it's Apple's bad design in that era that caused the problems, not Intel. Don't get me wrong, I'm not saying that AS isn't much cooler, it is, I'm just saying that the problems with the Intel laptops turning the fans on at the drop of a hat were actually Apple's fault, not Intel's. I would bet a lot of money that if they put an Intel in the new M1 16" MBP body, with all the same cooling design, it would really surprise you how rarely the fans would turn on, and when they do, for how short a time they stayed on.
I wish I had your 2015. My 2015 gets hot and loud. I even replaced the TIM with the best stuff out there and cleaned all the fans during the pandemic. It was marginally better. I've been waiting for the redesign, but I've been very close to offloading the 2015 for an M1 in order to be rid of the heat and noise. I'm glad I waited, but I'm definitely happy to put my 2015 behind me.
 
The graphic lines of airflow don't make sense. How does the cool airflow come in, spin clockwise, then exit as hot from a counterclockwise direction?
When I first saw your comment I thought "another armchair engineer". Then... I looked at their graphic closer and I feel the same way as you. If it does work this way, I'd love to hear how because its counterintuitive.
 
IDK…I’m glad Apple has finally updated the thermals inside the MBPs, it’s necessary. May the M1 Pro and M1 Max deliver on this promise of “rarely needing [the fans] …”
For the past several years, every new 15 inch MacBook Pro and then the 16 inch MBP featured updated thermal ?

Really, how strange! I literally use mine on my lap in my boxer shorts on a daily basis. Mine is the 15" btw, is yours too? Or the 13"? Maybe that could be the difference? Also, I am rarely doing much that stresses the processor, and yeah, when I do, the fans do kick in, it's not physics defying or anything. It just runs cool and quiet for the vast majority of things I use it for. I did have problems with Chrome causing it to fire up, but then Chrome did an update that lowered it's CPU usage and that fixed that.

And again, don't get me wrong, I am 99% likely going to get one of the new 16" MBPs with AS, as I have been waiting all these years for Apple to finally build a machine worthy of replacing this ageing piece of magic.

Just going to wait patiently for the actual reviews and feedback over the months, and to see them in person, before deciding which one to get, and how much RAM I need. Current most likely candidate is the lowest power CPU 16" option: M1Pro 10/16, and with 2TB, and either 16GB or 32GB RAM. If I choose 32GB, then it will be tempting to pay the little bit extra to get the M1Max chip for the extra memory bandwidth. But tbh, if they made a 16" M1 8/7 or 8/8, and I decided 16GB was enough, then I'd happily get that option.

If that were true, then at least some of the Windows laptops would have gotten the cooling right, but all the ones I hear about (pun intended) have trouble keeping the CPU and GPU cool and suffer the same problem. It's pretty clear it's Intel's fault. Yes Apple could have some of the blame, but they all have a problem even if it sits on a desk with a fan blowing on it.
 
I agree, especially now with the notch (which I am fine with). Add an option to make the menu bar non-transparent and that notch will disappear in Dark Mode.
You don't need dark mode but you do need a dark wallpaper to make the menu bar dark with white lettering.

There isn't a single Windows laptop maker that makes a decent laptop, regardless of Intel. They are simply all hopeless. These companies do not have a single visionary leader amongst them. Unfortunately, the climb to CEO requires competitive traits that far out compete the traits actually required to have the correct design visions.

Anyway, you are basically calling me a liar, as I literally sit here with my 2015 15" rMBP on my lap in my boxers typing this.

In System Preferences, change the desktop background to a solid light color. Then in General preferences, change between light and dark modes. Notice that while the dock changes color, the menu bar remains light even when set to "dark" mode. While in dark mode, click on any menu and notice the light colored menu bar with dark menus. The proper solution should be for Apple to make the menu bar color consistent with the light/dark mode setting just like the menus and dock, not telling people they are using the "wrong" desktop background.

In his defence, he didn’t appear to be questioning your honesty, as he quoted and only seemed to be responding to your assertion that Apple was more to blame than Intel for the Intel Core thermals. I think everyone believed you when you said that you surf the net in your underwear because why would anyone lie about that? If you really want to show off the effectiveness of your MacBook thermals, though, you should run a 4K Handbrake encode of a 2 hour movie and redo the photo when “90% completed” is visible on the screen. That would be even better proof of great cooling, though it does amaze me and seems ridiculous just how much CPU processing power seems to be needed for simply browsing the internet these days.

Also, some of the Microsoft Surface devices are actually pretty well designed, even though I’m not that much of a fan of touchscreens on Windows.

You do make a good argument and some good points. I am not saying that my laptop doesn't run pretty hot if I did run the test you suggest, but I'd suspect that iPads and M1 laptops would run pretty hot with those jobs too. And sure, not as hot as the Intel, and again, I iterate, I'm not saying the Intels aren't hotter, I'm just saying that a lot of the blame is gimped cooling of the late model Intel MBP/MBA's.

I'm a bit angry about the subject, as there are also these, that no one seems to have bothered watching, even though I've posted them on these forums a few times when this idea that Intel is entirely to blame for the late model MBP/MBA's running so hot. No one ever ever replies to say, oh wow, I had no idea, that is mind blowing, jaysus, I can't believe what Apple actually did to gimp those machines. No one. Ever. It's all just like a religious argument for people, they have a set idea that can't be budged, even in the face of overwhelming fact. I'll be curious if you do though, as you do seem to quite an open minded person.

No, I don’t have a late model Intel MacBook Pro, but I do have a 2018 Air and the cooling is insufficient (which became even more obvious when I got an M1 model.) From everything I’ve seen, it definitely did sound like the cooling was insufficient for at the very least the original i9 MB Pro, and it appears completely ironic that they seem to be improving the cooling for a CPU that surely needs it less. I’m not saying I’m unhappy they are doing it, just saying it would have been nice to have it earlier. That said, I would guess they likely have been improving it based on all that previous experience and would have used it for the new models if they were Intel and we should all be happy they didn’t just think “we don’t need this anymore with our new cooler chips!”

I have a maxed out 15" 2015. It doesn't take much for it to get hot and have the fans going. I also have a work issued hp with an i7. It's a great windows laptop, but it also gets hot with not a lot of stress with loud fans going. I'm super excited to finally have a laptop that won't be a heater or make so much noise.

While I don't disagree that prior MacBook cooling designs were average at best, I also can't say I've ever seen Apple announce a cooling design (other than fan-less) in any prior MacBook launch. The only times I can remember Apple making a big deal over their cooling design was for the last 3 Mac Pros - trashcan, iMac, and cheese grater. Remember iMac Pro? "Up to 80% more cooling over standard iMac". All reviews I've seen confirm iMac Pro runs near silent with most apps with minimal throttling.

So with this announcement of the all new cooling system for both MacBook 14 and 16, Apple is going to look real stupid if the results are noisy and/or a lot of throttling. I doubt that will be the case.

But I do have one question - where does Apple specifically say that both 14 and 16 have two fans? The 14 is basically a 13.3 body which only had enough space for one fan. Are the 14 fans smaller so they can squeeze in 2? Are the 14 fans thinner so it can sit on top of PCB space (remember how the prior MBP pcbs literally have circular cutouts to accommodate the fans)?
 
You didn't watch the vids did you?
The guys repeated shock at a fan that is known to be for venting just the case is just kind of strange, or maybe it is an old video before this was a fairly well known fact. As I said, the cooling is insufficient for the Intel version of the Air, so I thought I was agreeing with you. Linus trashing a heat sink isn’t one of his better moments, but he definitely knows how to get hits. I didn’t watch the whole way though, though… is there a twist at the end?

I bought the 2018 Air refurbed later after already knowing this stuff because I hadn’t bought a Mac since 2012 when the parts all became soldered, so I was used to not having top speed and just wanted the cheapest notebook with the current OS, as I now consider them non-upgradable short term investments. Buying the M1 version last year, however, suddenly made the Air seem like a perfect fit and that I was no longer just settling. The Air was designed with just a heat sink (and an at least sometimes poor one, judging by the Linus video) and the fan was tacked on to cool the case when it got too hot. Crappy design for the Intel processor, but works well even without the fan for the M1. That is my personal experience and your mileage may vary, as the Intel version actually worked okay for me and was fine until I had the M1 to compare. I might feel differently if/when the keyboard craps out on the 2018, since this is the one everyone apparently hates.

You have a very very kind description of this cooling design. As an engineer, I am nothing but appalled, and it is so incompetent, that it clearly has to be deliberate, there's no other explanation.

I didn’t think “crappy” was being particularly kind, let alone very very, but okay. I would say it is more of a realization that they obviously wanted to do a completely fanless design with a low heat cpu and realized they couldn’t scrap it completely. Again, the M1 version made me a believer for the first time in 10 years, and using it has made me see what they had at least been trying for with the earlier model. I actually prefer completely fanless now, as I don’t have to think about whether I’m blocking a vent. My HP Pavilion 16.1 has air intakes on the bottom (speaking of wonderful engineering), so I’m always worried I will block the airflow, and it heats up quickly at the best of times.

The barely touching heatsink was pretty egregious, but I’m not sure I believe that is real issue or perhaps a one off, as Linus tends to be pretty theatrical because it makes for a great show. I could make the fan come on by compiling or rendering video, but I didn’t really get any slowdowns that would indicate a major throttling problem, which would be pretty unbelievable with a bad heatsink, let alone one that didn’t actually contact. It actually worked very well, it’s just that the M1 version worked better with no worry about the fan at all.

I'm fine with fanless, as long as you understand that the fanless M1 MBA's throttle performance as it heats up. Which is perfectly fine if you're not wanting the full performance of the M1 (and most people don't need it), but then they may as well have put a lower power chip in it. Also, the fanless design is not at all the same as the thermal design they used for the Intel laptops. With the M1, they added big heat pads and so on to help dissipate the heat without the fan. The design is chalk and cheese.

The heatsink not actually touching the chip is definitely a real issue. If you know anything about thermodynamics and materials science, then you would be absolutely appalled. It's so important that Heatsinks are not only perfectly joined to the chips, they also smear a thin layer of a special thermal compound to ensure the best possible heat transfer, so to actually have an air gap is beyond belief. Apple engineers aren't dumb, and thus this is only possibly explainable as being deliberate in order to make the Intels seem hotter than they are, as Apple would have been well committed to the M1 design by then, and wanted to make it seem even better than they are (and yes, they are actually brilliant, so they didn't need to pull this stunt).

I hope you can understand that I am not at all knocking the M1 and the machines they are in, they are awesome, and I will be buying a 16". What I am saying is that Apple absolutely bombed the thermal design of the machines that the late model Intels were in. They bombed it so badly that I can't see any other explanation than that it was deliberate sabotage. And it annoys me every time someone comments about their Intel machine being a heater, and putting full blame on Intel. It annoys me extra, that when I try and explain how much Apple contributed to that problem, they don't seem to get it at all. Oh well. Anyway, I'm done here, there's nothing more I can add.

It's not strange reasoning at all... I object to the notch because it eats into the screen ruining the aesthetic. It looks dumb and it's completely unnecessary especially in a laptop. It really bothers me that much and evidently judging by the comments I'm seeing here at MacRumors and elsewhere, that opinion is not unique to me alone.
Funny how this poster is upset that you don’t like the aesthetics of the MacBook.

Strange world nowadays.

I would put it down to manufacturing defects. It's quite unlikely that Apple engineered something like that as designed.

I had a router than would shut down one of it's WiFi chip after running the router for a couple of hours, depending out how hot is the ambient temperature. Turns out the thermal pads used are not fully in contacts with the chip and the heatsink. Replacing the thermal pads and reseating the heatsink properly fixed the problem.

From what I know, coolings are designed as a system. That's why some devices should not be powered on with an open case over an extended period as it interferes with air-flows as the designer intended, resulting in overheating. Looking at just one component of the entire system and declaring that it is wrong is probably the wrong conclusion to be drawn.

I haven’t hard tested M1 throttling myself because it hasn’t been noticeable, but a search indicated 15% after 10 minutes sustained. So I’m happy they didn’t put a lower power chip in, as 10 minutes sustained load doesn’t occur on my XCode builds (small projects), so would only affect me for video renders, and 85% of higher power after 10 minutes in those cases is still better than a lower power cpu at 100% in all other uses. Have you looked at the teardowns? That big heat pad is just a spreader to where the fan used to be located. Not exactly a massive redesign, just a retrofit for the original, existing space.

So yes, I do know how a heatsink works and, as an engineer, you should, too. If you actually read my comments about my Intel Air, I said “I didn’t really get any slowdowns that would indicate a major throttling problem, which would be pretty unbelievable with a bad heatsink, let alone one that didn’t actually contact” If you’ve got an air gap, Arctic Silver will not fix it. I don’t believe that an M1 Air would run reasonably without the heatsink contacting, let alone an Intel Air. So, yeah, I call ******** on the heatsink not contacting on a correctly built Intel Air, whether it makes a good video for Linus or a great conspiracy theory. Apple may not have any competition in the Mac market, but the fact you can compare other Intel notebooks means they would have to be insane to intentionally hobble their MacBooks. It would actually make a bit more sense with the Apple Silicon, as you have no other direct benchmark, so they could hobble the low end to make the high end look better, but then they still have Intel and AMD to compete against, so it would still be crazy.

If you truly do believe Apple intentionally overheated the later Intel MacBooks, you shouldn’t even be buying another. It is madness to support a company you believe that about, because it is against your own self-interest to purchase from a company that would intentionally design defects into their products. I didn’t buy a Mac for 9 years because I didn’t like that they made them non-upgradable, so I just kept upgrading my 2011 model, but at no point did I think they made an intentionally defective product, just very annoyingly sealed ones. Unintentionally defective, sure, it happens. Too often.
