There are countries with way hotter ambients than Germany, and CPUs have been documented to also work just fine there.
It's a genuine question though. I've got a ThinkPad P14s (gen2) sporting a AMD Ryzen 7 PRO 5850U CPU. The fans start spinning under sustained workloads (compiling, watching 4K youtube in fullscreen) and that at a room temperature of about 22°C. + 15°C seems non trivial. Granted I could just go outside today and test it out but I am not _that_ curious.
I have a Lenovo with a 5800U and temps are just fine. Never goes over 70C when benchmarking Cinebench at max boost on all cores. Pretty sure you're good if you at least dust the cooler regularly and repasted it correctly at least once since you bought it.

Blame Apple - Linux is still a 2nd grade beta OS as the team trying to port Linux to Apple is still working on reverse-engineering many of the parts of M1 / M2 SoC. Until Apple actually provides documentation to system developers, we'd be fools to buy and trust the M1+ platform.

Idk if this is too OT but I wonder how it would fare with an ambient temp of 37°C (forecast for today).

In my opinion, this is an incredibly stupid design choice.
After being once caught by surprise, now I check carefully for a specified working temperature of at least 40 degrees Celsius, whenever I am buying any laptop or desktop computers.
This, for example, disqualifies all Gigabyte small computers. Moreover, any computer which does not specify explicitly the maximum working temperature must be automatically disqualified, because it is overwhelmingly likely that it has been designed for 35 degrees Celsius and not for any higher temperature.
Some computers are guaranteed to work normally up to 35 degrees Celsius and to work with reduced performance between 35 degrees Celsius and 40 degrees Celsius, for instance many Intel NUCs. This is perfectly OK.

A while ago my laptop started running around 10°C hotter than it should have - turns out the iGPU was going wide open throttle for no apparent reason.
What I found was that CPU-intensive tasks slowed down as well, because those 10°C make a huge difference in terms of when the CPU starts throttling.
I wasn't bothered by this too much, even though I had to disable turbo altogether, until the first heat wave of the season hit - +10°C from the iGPU combined with +10°C from the heatwave slowed the device to a crawl - it was the first time I briefly saw it hit 102°C - that is actually above the usual safety threshold.
I think people in different climates either have A/C or are used to different levels of performance.

"AMD also included battery life benchmarks comparing the Ryzen 7 Pro 7840U against two Core i7 models and the Apple M2 Pro, with the former both having a battery capacity of 54 Wh, while the latter had a 69.6 Wh battery. Meanwhile, the Ryzen 7 Pro 7840U system was equipped with a 51.3 Wh battery yet managed to deliver longer battery life than all three competing laptops, with the highest delta being a 70% advantage over the Core i7-1370P"

I wouldn't be that strict. It's not like many PC laptop manufacturers provide drivers or documentation. Buying a laptop like Acer or other known brand, you're still relying on a few reverse engineered devices.
Meanwhile on the M1, even keyboard support was implemented fairly late and is not mainline yet.

This is true, but nonetheless many computers are guaranteed to work only up to an ambient temperature of 35 degrees Celsius. In my opinion, this is an incredibly stupid design choice.

#30I hope this processor finds it's way into a miniPC such as the ones sold by Beelink or minisforum. Having a quiet but beefy tiny desktop with 8cores/16threads tucked away out of sight would be a superb machine to have, and would also make me consider ditching any laptop.
