Evil Controllers Boss States Why They Think Sony Didn’t Include PS5 Controller Back Buttons by Default



I hate back buttons. I have them on my Xbox style PC controller, and I turn them off. I tried them at the start, but I'm too clumsy, and hit them too easily. So no thanks. If they were included by default, devs would be more likely to use them, introducing the potential to have difficult control inputs in certain games. I think that's why MS didn't include them either.

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:

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.

Exactly, the intake is on the front, from both sides (top&down in horizontal position). It takes cold air and pushes it to the middle layer through the heatsink to the back of the consol.

Something like this:

Cant wait for an official reveal of Elden Ring.

About the PS5 NMVe slot, I think its safe to say Sony factored any heat concerns for the slot when designing the PS5.

I'm just hoping some back button add on patents that were found become a thing. So far its back buttons and a charging piece.

There's still complications to adding another variance to the setup; different drives running at different heat vs. no expansion being the best scenario. And of course the existing variance of ambient room temps.

It doesn't really matter if it's near intake or ventilation though does it, like overall this is a zero sum game? It's either heating the air more on the way in, or getting hotter air on the way out. Either way that hot thing increases the need for active cooling.

I personally hope Sony sells an add-on drive that's a duplicate of the internal. I would trust that having the best perf and being tested the best for airflow.

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.

A very insightful post. Thanks ToTTenTranz ToTTenTranz

There's still complications to adding another variance to the setup; different drives running at different heat vs. no expansion being the best scenario. And of course the existing variance of ambient room temps.

I don't think there's much variance with M.2. drive heat generation. Most drives I've seen top out at around 7W of power for sequential writes at the top end. Slower drives consume less, and I'm sure Sony would have included a safety margin in the design of their cooling setup for this element (could be as much as 50% to 100% design margin).

I don't know if there is an actual standard limiting power consumption for M.2. drives, but even if not, drive manufacturers aren't going to be very willing to put drives out on the market whose performance puts out more heat and consumes more power than their competitors. So the natural competition of the market will keep drives around the same or better ranges for the power consumption and thermal output characteristics.

It doesn't really matter if it's near intake or ventilation though does it, like overall this is a zero sum game? It's either heating the air more on the way in, or getting hotter air on the way out. Either way that hot thing increases the need for active cooling.

It certainly matter for the cooling system design. The temperature differential is the driving force for heat transfer. A smaller temperature difference between the air an finned area surface of the heat sink means a lower heat flux, reducing the efficiency of the cooling system.

The console will be designed for the worst case, e.g. 40degC, and a warning label printed on the box for folks stupid enough to try gaming in a room hotter than that (tbf, they'll probably die before their console does).

They have variance in heat sinks; from small to large to no heatsink. They run at different temps because of that.

I did some googling and it's really not that big of a range though: https://www.overclock3d.net/reviews/storage/pcie_4_0_nvme_ssd_roundup/12

Also super interesting that the motherboard heatsink they tested was across the board better than those supplied by the device manufacturer.

It certainly matter for the cooling system design. The temperature differential is the driving force for heat transfer. A smaller temperature difference between the air an finned area surface of the heat sink means a lower heat flux, reducing the efficiency of the cooling system.

I'm talking specifically about whether a heat producing device is near the intake or near the exhaust. Both carry issues; a hot device near the intake will be cooled more easily but will also cause the air flowing into the system near that device to be hotter. A device closer to the exhaust is of course getting hotter air blown over it.

It sounds like these devices generally work fine w/ a heatsink and no active cooling. So that's why I'm asking about the placement of the drive; if the drives themselves don't really have major thermal issues with a decent heatsink and no active cooling, than the issue really is that they are another heat producer inside of a closed system.

But I'm asking this as a question because I don't really know; for a device like that logically it seems like it would actually be better near the exhaust, rather than as a heat producer near the intake. But I'm probably wrong as I don't doubt Sony's engineering or anything just seems odd to me.

Sure but the drives with the largest heat sinks don't exceed 7W. That's what i'm more focused on.

You're right, but for a console, wherever they locate the M.2. drive expansion bay in the console, they'll simply design for the expected air temperature.

If they located at the intake, they need a heat sink with less area. Deeper in the console, they'll need more area because of the hotter air flow.

It sounds like these devices generally work fine w/ a heatsink and no active cooling. So that's why I'm asking about the placement of the drive; if the drives themselves don't really have major thermal issues with a decent heatsink and no active cooling, than the issue really is that they are another heat producer inside of a closed system.

If it has a heat sink for PC installation it requires active cooling within the PC open enclosure. There is a net air flow through the PC chassis with air flow driven by fans, so while it's not as directed as in a console it still qualifies as active cooling.

But I'm asking this as a question because I don't really know; for a device like that logically it seems like it would actually be better near the exhaust, rather than as a heat producer near the intake. But I'm probably wrong as I don't doubt Sony's engineering or anything just seems odd to me.

Why do you think it would be better at the exhaust, where air is hotter and thus there'll be a requirement for a bigger heat sink?

For a small 7W heat dissipator, you're better off at the intake because with the coldest air temperature, and the air flow sized to cool the bigger thermal output elements of the console (i.e. the APU and RAM chips), cooling 7W of heat from the SSD likely won't raise the air temps across the SSD heat-sink all that much, meaning you can get away with the smallest possible heat sink for the SSD device.

Where this was back when KC:D started development, FUCK. Amazing news.

No only wait till it's going to be seen, how actually programmer involved the whole process is.

Took Microsoft long enuff. Sony took what was learned on PS3 and carried it over too PS4. Most probably PS5 too

No that's totally different approach of API, which Sony have, you basically can draw pixels from command line there.

1. The PS5 is the easiest console is history to clean.
2. Why didn't this person clean the console instead of making this video to form FUD.
3. Many devices with fan accumulate dust around the vents, but how quickly is dependent on the dust in the air.
4. Damn, this muddaf@cka house is nasty, took my PS4 a year before it looked like this. He should of thought about that before making a video.

Do people not realise that if you open a freaking window for a few hours a day, you're house/room dust build-up problem will more or less disappear.
Even then is almost impossible to gather that much dust.My heating broke down. So I haven't opened the windows since I got the ps5.
Got sick and barely left my home since then, I have a cat and live in a more industrial zone and even worse my kitchen and the living room are the same room, yet my ps5 is as clean as new.
Unless you actively put saw dust on it, it is impossible, be it for Ps5, XSX or XSS.

But not if you live in the Sahara Deseret where apparently this mf is living with that much shit accumulating.

Yeah, this person is probably got his console setup in his woodwork shed or something. It doesn't even look like dust because it's yellow. Looks like saw dust.

Because I've read on forums (including here) that these drives actually do fine in an external passive cooled enclosure, that's why I wasn't taking into account the airflow of the tests done inside a PC. Although they aren't likely working at their top speed, so that might be why.

But anyways, like I said, totally just random thoughts and I'm sure Sony knows what they are doing.

I bet someone does a mod to use internal SSD expansion(once its been enabled), but have drive out of the PS5

There are NVME extension cables but I don't think any currently can do PCIE 4.0 speeds.

But might be possible in the future, not sure.

But this whole thing probably won't be an issue other than potentially making your PS5 a bit louder.
