From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

When will we see fanless models? That is one of the defining features of the M1 Air.
I like silent laptops but sometimes I want to max out the power budget and get work done without worrying about thermal throttling. Having a fan and customizable power settings gives users a choice. Apple takes that choice away.
When I got my first Raspberry Pi (4B), I was kind of shocked at how hot even my passive Argon case would get. Though I am guessing a more powerful and efficient ARM or RISC-V CPU would not spike to 100% so fast. But when I got my Pi 5 I made sure to get the official case that came with a fan while I waited for the more powerful active cooling fan to release. So much better at running stuff like YouTube or other media without hitting thermal issues (got the active cooling Argon One for my 4B with similar results too).
Having more powerful ARM/RISC-V CPUs that can actually handle stuff I expect a full on laptop or especially a desktop will be awesome. But while we are in the "still not as good" period of these CPUs both matching x86_64 and programs for them being full versions. The inefficiencies of either needing emulation or just very un-optimized code as devs are getting the hang of ARM/RISC-V coming from x86 mean those temps are easy to hit.
Installing a fan negatively impacts the passive cooling ability (at the absolute least by taking space that could be occupied by a bigger radiator and by obstructing the airflow), so it's always a tradeoff.
Apple wanted to make it passively cooled, and it wouldn't be possible at decent loads if a fan would be installed alongside passive cooler.
I have a 2021 Asus Zephyrus G14 unless I run a game, that thing is running without active cooling. Seems like a solved problem.
Solved for larger laptops.
Macbooks are significantly slimmer, and have way less internal space that could be used to make a combined cooling system that would be passive most of the time.
The G14 is 14 inch and has a dedicated GPU, so without one the cooling requirements are far less.
I see it more of a limitation, you don’t want your laptop to warm (and it shouldn’t in light use), but you want to cool it for the few times it does.
And they thermally throttle due to the heat.
Not necessarily. I own a passively cooled x86 laptop that runs just fine without throttling - granted, it's based on Celeron series CPU, but when we talk of ARM laptops, we normally don't talk powerful machines - Macs are rather an exception.
