Sony's goal was to be quieter than than the prior generation, but seemingly within design constraints that lent to the more shallow box and use of a blower fan. Other elements, like what seems like at least some reports of coil whine and uniformity issues with fan supplier and fan installation point to other factors being of higher importance than noise. The PSU seems to have enough in common with the prior gen's choices that it might be that the components lack the much higher noise floor of the the PS4, or the higher power and more variable PS4 might have made things worse.
Choosing an axial fan of substantial size and customizing it in terms of blades and mounting, and having a design that might trade off some manufacturing cost or volume can give more opportunity for a lower noise floor and more consistent installation.
It should be pushed out the back at sufficient speed. If the space is enclosed or airflow constrained enough to change this, poorer results would be expected.
If Microsoft prioritized passive flow, there would have been substantially more airflow through the bottom (mostly obstructed) and not through a partially obstructed side grill. Some of the choices for hardware placement also disrupt airflow if you're hoping for results without a fan.
The fan's direction may be related to dust and debris considerations with the innards of the console being on a straight path from above.

But isn't Xbox just as silent?
Between the two leading consoles, most of the reviews and impressions that I've seen gave the Series X an edge in terms of noise.
The PS5 also seems to have some noise issues that have at least anecdotally been more often noticed, perhaps because it has a much lower noise floor than before.
Real world. Heat is a form of energy, and can only move from hot to cold. Even things that make things cold like an air conditioner or freezer don't create cold, they remove heat. That's why AC units need to be mounted half outside, completely outside, or otherwise vented so they can discharge that heat away from the area you are trying to cool. It's also how heatsinks work. Heat will naturally move into the heatsink and be naturally wicked out into the fins and discharged into the air even without a fan to assist. Adding a fan just accelerates this, to a great degree of course.
It's the same with air pressure. If you create an area of high pressure, that pressure will dissipate to lower pressure until equilibrium is achieved. For example, if you blow up a balloon, the air pressure inside the balloon is higher than the pressure outside the balloon. Let it go, and the pressure rushes out the opening until pressure is normalized.

WRT hot moving to cold, this is true if the particles are relatively static, like say a copper wire or a pan on a stove.
But for gasses (like air) it's more hot and cold air displacing each other as DSoup noted above. In this case due to the difference in density combined with the effects of gravity, cold air displaces hot air. As pressure is equal at any given point, the path of least resistance means that the colder air (in very simplistic terms) will displace hot air from the bottom up as the path of least resistance for the displaced hot air is upwards.
However, pressure also equates to heat. Or another way to think about it is that as pressure increases due to heat (energy) it is displaced or "seeks" lower pressure areas where the heat (energy) is gradually lost. Thus as hot air is displaced towards lower pressure, it also loses heat as it expands which then cools it eventually causing it to gain enough density that gravity pulls it back down and the cycle repeats. Hence leading to the weather patterns on this planet.
Anyway, short answer is that for a gas, it isn't that heat seeks cold but that hot air is displaced by cold air for various reasons. Which is different from a solid where heat propagates to cold, which can be seen as "seeking" cold.
Of course, for gasses there is some movement of hot to cold in the form of hot air particles transferring heat (energy) to cold particles, but it's relatively small compared to the effects of displacement.

Yes, convection was the word that I was searching for
https://en.wikipedia.org/wiki/Convection
Even if it's an open topic for science because the guy that installed my air conditioner in the wrong spot reassured me with "Don't worry, in any case, hot air moves to the bottom"
Let's split the thread?

Was he Australian?
It was already clarified later that "6GB to the OS" is incorrect, it's 6GB to that memory section, with 2.5 GB reserved for OS.
shit, did I miss that?
yea that is what the GDK documentation indicated. But that was June, so I was worried perhaps things changed since then.

Unfortunately, someone ... somewhere is only going to look at the presentation video or transcript for it and the internet will likely be flooded by articles or reports that XBS-X only uses 10 GB of data for games. Or I'm being overly pessimistic about the state of the internet.

I very much doubt that, maybe forgot as it wasn’t important to remember.

you mean realistic?
I mean, I watched the video, and I was under the impression that they went back to fix the mistake in the video.
Yea, in my mind, OS was sitting around 2.5GB from much older tech talks. Surprised to see the slide and text the way it was, that should have been vetted. Not sure why that even happened.

I can't imagine many (any? Medium maybe?) games are using more than 10GB on the XSX yet.
Also providing the IO system is able to feed data fast enough, then does it matter it has 10GB or 13.5GB available to it? A more efficient steaming system would be more effective, presumably. Looks like the system is specifically built around fast data transfer.

That's not possible.
