Sony PlayStation 5 CFI 1116A - new revision and smaller radiator, therefore wors

Dear,

I am contacting you with a request and an explanation of the issue in the topic.

Namely, it was hard to buy consoles "at a normal" price, and finally I succeeded (console with disc input), which I was happy with.

It turned out, however, that this is a new revision CFI-1116A 01Y supposed to be better in theory, but in fact it turns out to be something completely different? because compared to the original version, it has a much smaller heatsink (about 300g is lighter in general, the console) and supposedly heats up more, because the temperature of the air ejected from the console housing has more degrees.

I do not know if anyone is in the subject, but maybe someone will comment and advise if this can affect the performance of the console in games, because this is a fundamental question for me ..., besides, will it also affect the life of the console.

I can still return the consoles (although I don't know if I will find the original older model),
- or maybe there is no reason to worry and it may turn out that it is completely different and the console is better or on par ..., I know that older consoles had, among others, Noisy coil problems?

What is your opinion?, please advise me what to do.

Thank you

PS supposedly a smaller radiator, as people write, is a cut in production costs and faster production due to the possible lack of raw material availability!? - I wonder if that's the case or Sony was guided by something completely different - only then WHAT ...

are you talking about it?

Yes, e.g. This is what I mention in the video you shared above

I'm not an electronics engineer and I don't know if a smaller radiator can be as efficient as a larger one (is it possible?) - of course you have to take into account whether the design of the newer console has also changed in terms of application, e.g. a different fan or other solution which is supposed to give a better effect than the previous one, but as I wrote, apparently more heat is emitted by the new console ...

-some write that it's better, because more heat comes out of the console than stays

-others write, however, that it throws out warmer air, because it warms up more ...

The heat expelled from the console is the heat received from the elements, which is theoretically better, the question is whether the speed of the air flowing is the same.

Unfortunately, I do not have such knowledge ... do you mean if the fan spins faster or the same as in the old console?

If the fan in the new one spins faster then ...?
And how is it just...?

Not so much faster as it is constructed in such a way that it pumps larger amounts of air.
The more air flows through the heatsink, the more energy it will take away.

So if there is a small radiator, more warm air will pass through it and the air expelled by the fan from the console will be hotter?

I understand it right?
- if so, the new console with a smaller radiator is worse.

Although the larger the heat sink is, it cools more and therefore the air expelled from the console is less hot?

And the heat sink is designed to cool what components, such as the processor?

Damn, it's hard for me to understand it a bit, then which version is better, but you mentioned something in the post above, that if the console emits more heat from the housing, the better ...?

The heat sink is just a heat exchanger, how much heat it is able to transmit and return depends not only on its weight and surface area, but also on what materials it is made of and how much air flows through it.
In passive cooling, heat exchange is based mainly on convection, which means that radiators must be large, in active cooling it is the fan that forces the flow of cool air and thus heat dissipation.
Perhaps in the earlier version, the PS5 cooling posed too much resistance, so that the air flow was not optimal and thus heat dissipation.
In general, someone who is familiar with thermodynamics would have to comment because perhaps my assumptions are wrong.

In the older console:

- radiator was bigger
- there was also a copper base
- there were 4 heat pipes?


In the new console:

- the radiator is smaller
- there is no copper base (and generally less of it)
- there are 2 heat dissipation pipes
- changed the windmill (including blades and inclination)


An experiment of both was done where the temperature of the air ejected from the console housing was checked and it turned out that

- the old console has 3-5 degrees less
- the new console has 3-5 degrees more

There's a storm on the internet

Some say that the higher the temperature at the outlet of the housing, it means that there is a higher temperature inside and the equipment overheats.

Others claim that the higher the temperature at the outlet of the case, it means that there is better cooling despite the smaller heatsink

I will add that the processor that is cooled in both consoles is supposedly the same.

Until someone measures the temperatures on the processor itself, it will be a guess.

Exactly...

So I understand that if the temperature of the processor will be the same in both consoles and there will be differences at the outlet, a higher temperature will always mean worse cooling, right? (and in this example, it will be worse heat dissipation from the console housing).

In my opinion, if the processor temperatures are the same, the new cooler is more efficient, because despite its smaller size, it is able to dissipate the same amount of heat from the system.

So here everything is about the temperature of the processor, not the air ejected from the console.

Because assuming that the temperature of the processor is lower and the air expelled is higher, it is a better cooling than the processor would have a higher temperature and the exhaust air would have a lower temperature, but in such a situation could the temperature of the expelled air be lower at all?

I guess that the temperature on the processor is once and the temperature in the housing itself is two, although I assume that the air exhaust fan should be as close as possible to the edge of the housing, unless the console itself has so many holes that the air comes out of the console itself.

The higher temperature of 3-5c also translates to other components? and wear of their parts...

Yes, temperature affects the service life of components, especially capacitors.
I do not know to what extent these few degrees will translate into a general lifespan, in power supplies for TVs or monitors, capacitors are commonly (you could even say intentionally) placed close to heat sinks that get quite hot, which makes their lifespan quite short.
The only question is whether in the new PS5 the higher temperature occurs throughout the housing or only in the ventilation ducts.

And please tell me you wrote that the important issue is not so much the size of the heat sink as what material it was made of, I assume that copper is better than aluminum, right?

According to you, it is possible that, for example, in the new version they changed from passive (although there was a fan there, but also a large radiator) strictly to active? and which do you think is better?

And finally, which means higher power consumption, e.g. 220w and 230w

So what is the new ps5, however, not worse?

In the video, among others the new console has a lower cpu temp and higher for ram and disk, but the cpu is more important? - I do not know how to temper the data from the photo from the link below ...

As for me, the new PS5 actually has better cooling because it removes the temperature from the APU much better, of course, at the expense of radiating some of the heat to other elements.
This could be remedied with a more efficient fan, but it would again increase the volume of the console.

I wonder why it has a more efficient processor cooling as it has a smaller radiator (of course something else could have changed that I don't know). However, people write that if there will be more demanding games, it will be the other way around in relation to the old console (with a larger heatsink) but why? like a new one, it already has a lower temp ... is it nonsense and again looking for a hole in the whole thing
