Think ther are a few things to factor in. Power draw, size and shape of Drives/size and shape of heatsink(if it has one), specs, has to play nicely with Sonys custom flash controller, even cost(may be a factor)

Possibly.
Would you explain?

From, what we 've seen so far , XSX/S struggle with Dynamic Resolution in the sense that is more difficult to regulate, between resolution and performance. Mark Cerny's words comes to mind , when he spoke about power budget and how better the ps5 can handle stressed scenarios, than a fixed clock machine.

Cerny mentioned it in the GDC talk.
They only drew lines across the APU for a FUDgenda.
The cold air gets pulled in from both sides through the vent and out the back like a vacuum, not an imaginary tunnel for internet clowns.
Again, even if it did (which it doesn't), how is that an issue, BUT NOT AN ISSUE ON THE PC OR ZERO AIRFLOW LAPTOPS?
PCMRs should be annoyed with Xbox fanatics for making their parts sound like cheap shit that will overheat and melt into RRoD, yet they somehow join in and throw their own hardware under the bus.

Sounds like you want to join the console wars even though you don’t own a console. Sure, join in, have fun. If that’s your thing.
Well at least you got the reaction from some of the sony warriors i was talking about. But good one.Sounds like you want to join the console wars even though you don’t own a console. Sure, join in, have fun. If that’s your thing.

Nope the fan should rotate the other way around to trap air in its blades otherwise it's not blowing anything here.Lets clarify a little more..

Lol, wut!!
"Brute force" is a silly ambiguous term that anyone can define any way they want to. It has no relevance nor meaning in any kind of intelligent discourse on the merits or drawbacks of computing hardware design.
It's a shitty meaningless non-criticism like "generic" that only fanboys use to argue against a product they don't like.
I think it's like this:
But I am probably wrong
Vents at the front of the console so the air flow goes in at the front, out at the back.
Yes, the air gets pulled in from the front, so while his drawing for the internal air flow path was over simplified, it was still correct in that the extension M.2. drives see the coldest air.
If you didn't know before, seeing the coldest air is a good thing, because the higher the temperature differential between the bulk air flow temperature and the surface temps of the heat sink finned area, the higher the rate of heat exchange.
It's an efficient cooling system design.

I'm not arguing where the hot air comes out I'm saying the fan rotates the other way around.Whaaaat?

You guys are fucking wrong the air is sucked through the inner part of that fan, so in this case it would be 90 degree to the side of the side of PS5 if that make sense. Like this:Whaaaat?
Should be in blue, but the retarded controls on Mac prevent me from doing so on first try. So yeah technically is going from front panels, but it's more like 3D, not planar.

The ps5 intakes are on the front and it blows hot air out the back so i cant see how blowing hot air from the m2 drive across the board is a good thing...looking the bay closer it does not have much space for air to circulate in also so its a direct radiant heat source right next to your fanLets clarify a little more..

PS5 fan draws in air from BOTH sides, pushes it through the duct (or only opening) where there is the heat sink.
The fan spins clockwise when looking at the side with SSD enclosure and disc if it is disc edition (some people here got the turning wrong way around).
And also SSD has two openings towards the fan (if you look closely when the enclosure is removed you can see those two slids) so there is active cooling by pressure difference plus the dissipation coming from the ssd sink if it has one (and if it has a sink, it is added benefit to active cooling with pressure difference as the air is moved through the sink and not just relegated to passive convection dissipation)

Also let me just add, for those of you with m.2 SSDs that have heat sinks, your PCs are basically open enclosures where there is little GENERAL pressure difference is built in total (either positive or negative) with fans blowing air IN or OUT,
and as far as a heatsink that doesn't have a fan right on top of it, the cooling efficiency of these sinks is up to how much extreme pressure difference you can build in total, an m.2 SSD with heatsink just sitting there with barely positive or negative pressure is just like it is sitting in any open room. If you are not fond of fans because they make a lot of noise and use custom or AIO liquid cooling, this is more than likely.
PS5 has an enclosure solution with precise openings for tightly controlled air movement, air will be sucked out in one direction and pulled in another, so the air in the enclosure will not be sitting idly, it will move independent of any heatsink, but as added bonus if it has heatsink then a heatsink in tightly controlled situation is even more efficient compared to open air/neutral pressure.

There's more room in there than people thought. Much more than most new gaming laptops or macbooks.Helps to see the slot but that's more or less correct.

In terms of the mechanics of heat transfer, assuming there is a heat sink, the heat sink isn't just an added bonus it's required.
The rate of heat transfer is a function of the temperature differential (principally between the bulk air flow and the heat sink surface temperature), the surface area for heat exchange and the mass flowrate of the air through the enclosure.
The pressure differential only determines the volumetric flowrate of air through the enclosure. This sets the mass flowrate of the air as well as the air velocity influencing the overall heat transfer coefficient (velocity influences the air flow regime, i.e. whether either turbulent flow or transient, which defines the boundary layer of air against the metal surface).
The convective heat transfer between the finned surface of the heat sink and the air (i.e. often the rate limiting step) is largely influenced by the amount of exposed metal surface available for heat exchange. Outside of the temperature driving force, which is largely going to be assumed as a basis for the cooling system design, in a console enclosure where noise is limiting the air flow-rate at the top end, increasing metal surface area will have the biggest impact on the overall rate of heat transfer.

SSD slot has alu plate underneath (on the right)
And theres many space to flow air (left side of the photo)

Negative pressure is what creates air flow. So yes, cool air does flow over the SSD.

Anyone can speculate on the reasons. This is no more official than a reasoning someone on here can come up with.
Negative pressure, or rather a negative pressure differential, is the driving force for air flow. So it's not saying anything different from what many here are saying.

as long as it is gameplay I'm ok with that.

I hope full gen 9 plus PC
I second that, less of the In-Game engine footage please, because that quote may as well just say CGI.
I've never really liked when footage states In-game engine.

It's FS game, so pretty much guaranteed consoles +PC as usual.

There seems to be some confusion on the maximum heat output we see on NVMe drive reviews and how that would translate to typical behavior when using them on a PS5.
The higher power consumption and temperature numbers, and eventual throttling, we see are always related to sequential writes. Here's an eaxmple of the WD SN850 that reaches 7GBytes/s read (not 7gbps btw). It's a M.2 drive that is sold without a heatsink, so the effect of the temperature output is more noticeable in the readings:
While playing games, the PS5 will use the SSD almost exclusively (>99.9% of the time) to stream assets from the mass storage, i.e. on sequential reads with block sizes over 64K.
In that particular case, the SSD without a heatsink doesn't go above ~46ºC. The temperature on these drives shouldn't be a problem while playing games.
I think the only time the PS5 ever needs to throttle down the M.2 SSD is when copying games from the internal SSD to the M.2 one
I see no need for the fan to run at higher speeds due to the add-in SSD. I think Sony will be allowing many different things on future firmwares, two of them being the custom fan profile optimizations (which had been announced already) and the support for add-in M.2 SSDs.
It seems that somehow these messages got mixed up and someone assumed the custom fan profiles were related to the add-in SSD support.

Wouldn't it be hilarious if Sony ends up LOWERING the speed of the PS5 fan or at least allowing for it to be lowered at need? Not sure what would get the "overheating PS5's" crowd first- a heart attack, or a stroke!There seems to be some confusion on the maximum heat output we see on NVMe drive reviews and how that would translate to typical behavior when using them on a PS5.
