Nope. Thats the way to make the M3. Add a bigger cooling unit and squeeze a bit more speed and call it M3.
Cannot tell if this outrage is parody or not.

Huh? How did they arrive at the conclusion that it's due to a supply chain issue? This line of reasoning doesn't make sense at all.
Smaller package, smaller heat sinks are definitely an improvement from Apple's perspective for a mobile device. Not to mention cost savings. All of these are reasons for moving to the new modules.
The SOC itself is using the same process as before. But the RAM modules must have used a smaller process in order for them shrink while at the same time offering greater capacity. A smaller process will result in better thermal footprint. Again, this is an improvement that is worthwhile in itself.
Note that the only part of the heat sink that shrunk is the part that makes contact with the dies. Obviously, because it has to match the size of the now smaller package. The rest of the assembly remains the same. Therefore thermal dissipation likely remains identical.
TLDR: smaller is better

You spend more time in this thread trying to belittle people for having genuine concern that their $3000 MacBook Pro (that they probably had to save for) will be worse performing than the one it replaced! Apple is not your friend. They don't care about you. They are far from perfect, especially these days.
I'm sorry, but how do you expect people to take you seriously when you use such language to describe a company whose laptops were openly mocked ON PRIME TIME TV? This is a company that has made extremely poor decisions about both macOS and much of its hardware over the past decade. Don't pretend that Apple Silicon marks the end of that nonsense either.
Have you?
Right and because they're Apple that means that they are infallible? Because they're Apple, it means that they don't make bad decisions? Get real!
Go pick up a Mac with butterfly keyboard and tell me how much of an overblown scandal it was. Or an iPhone 6 Plus. Or any number of the countless of other "scandals" that ended up evolving into Apple Repair Extension Programs and class action lawsuits. This kind of rhetoric gives these forums a bad name.
The text in bold proves that you are not of the affected audience. Please be a dear and stop talking like those that ARE of the affected audience don't have anything to worry about here. If you bought an M2 Pro Mac and are only browsing the web, you obviously won't have a problem. The fears come from those putting this machine under load.
It's also generally a bad look for a second generation product to have issues that the first generation product did not have. But, please do tell me how great your overkill M2 Pro is for Facebooking!
Overblown hyperbole is an understatement here. You do realize that people are buying 16-inch MacBook Pros to edit feature films, yeah? Just because you don't use your computer to its fullest, doesn't mean that there aren't people who do that will see worse thermal throttling than before.
Quit pretending you are one!!!
People on here are mostly consumers and Apple users that glom onto news and press. Jony Ive is one man. He's not the only person responsible for the Butterfly fiasco. And mind you, with that one, there were two disasters. One was the original keyboard, and two was the insistence that they keep trying to fix it before ultimately scrapping it. Hard to blame that latter one on Jony Ive.
At least Max Tech will at least prove their findings in their videos.

You haven't seen "controversy" until the AS Mac Pro is rolled out (on $1,000 wheels). Apple's M2 launch just prepping the crowd for the inevitable "8,1 is less powerful than the 7,1" furor (and non-expandable to boot, wheels still extra). I look forward to the day when my 6,1's non-expandable design is vindicated! Ha! Seriously, though, long live the 6,1!!!

Confirm to me you’ve never once delved into product planning without saying you’ve never once delved into product planning.
Cuz I have.
You have no clue how this works and it’s painfully obvious.
Good day.

Except the Apple chip is based on ARM, that's RISC and the entire point of RISC is incredible power efficiency AND excellent thermal dynamics requiring little cooling. But in the video in the first reply to this article they state diminished thermal properties die to the smaller heatsink, and yes more heat generally does mean poorer performance with CPU's as it try's not to cook itself.
A CPU running at 100 degrees isn't the best idea. I wonder how that will affect its performance when editing 4K videos for a whole day, as some users will want to do.
To me it looks like Apple did what Apple does, sacrifice cooling for design or quietness, that's why it's Intel models thermal throttled according to reviewers.

Late to the party and far behind on the thread, but this, tenfold.
I do understand (halfway) the complaint of Apple trying to work around whatever they have to solve but come on…
Somehow getting 20% to 30% performance increase in exchange of a single digit temperature increase is construed as a horrible deal. Some recent blender benchmarks paint an even better potential picture (which means it could translate towards anything 3D and games if developers get on it):
blenderartists.org
“that is pretty shocking that even the m2 max 30 core gpu is 40% faster than than the 32 core m1 max, and the 38 core is 75% faster.”
Intel achieved the 100+C redline from sleep idle temperatures IN SECONDS, it would do a short “turbo boost” and be left panting to catch for breath for the next several seconds.
This whole release has been plagued with “meh 5nm still”, “meh, it gets hotter”, “meh latest wifi/Bluetooth came too late”, “maaaeeehhh”…
But ok fine people, don’t buy it or get the M1s, they are at an even better and recurring discounts since these “meh it’s still 5nm and potentially ~many% faster M2” came out.

Mac: M3 - *Hardware accelerated RT (Part 1)
that is pretty shocking that even the m2 max 30 core gpu is 40% faster than than the 32 core m1 max, and the 38 core is 75% faster. given how early these results are coming in, i wonder if the are internal tests using those m2 specific patches apple was working on, or if that is still to come...

Maybe someday we’ll get a book from one of those engineers.

Interesting comment. Made me go hmmm...
Consider the die shrink.
Assuming moderate increase in core counts, logic and transistor numbers at a 3nm node then it would fit the HSF.
Waste heat goes down. Power consumption goes down.

Colder weather?
Supply chain or quarterly reports.

Intel looking at apple m2 max like 109C? We don’t run that hot !
Is it a lot to ask Apple not to compromise on product quality and customer experience since they charge a lot for their products?
Apple didn't give discounts when they put in smaller heat sink. Customers paid in full, so Apple is not entitled to blame supply chain issues for putting in smaller heat sink.
If we didn't get what we paid for, we have rights to complain.

… what?
This thread is based off assumptions and speculation. Apple never once even commented on it, let alone blamed supply chain issues.
You’re getting wrapped up in this topic as if any of this fact and confirmed by Apple.
In what way specifically is the product quality and customer experience compromised?
This is greatly misunderstood. The "heatsink" is the entire apparatus including the fans. From a thermodynamic point of view, the heatsink appears to be the same size. The metal slab in contact with the module acts as a thermal conductor to the thermal conductive elements that radiate toward the fans. The fans facilitate the dissipation of the heat. The slab itself has very little ability to dissipate the heat because the air movement is directed elsewhere and the slab does not contact the case (as far as we can tell from the video). So, a slab larger than the module provides no material benefit to heat dissipation. If Apple had reduced the size of the thermal conductors between the slab and the fans or reduced the size of the slab to be smaller than the contact area of the module, that would be a concern.

Where is it worse performing? Even in the MaxTech video posted here (which is .. a lot of click bait), it still shows it performing higher.
Apple has never been perfect, nor is any other company. But making a mountain out of a mole hill (who even knows if the mole hill exists, EVERYTHING about this issue is pure speculation at this point except higher temps) is pointless.
