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

eraeste 59328 18
Best answers

Does the PS5 CFI-1116A revision with a smaller heatsink cool worse, and can it affect performance or lifespan?

The smaller heatsink alone does not prove worse cooling; what matters is the APU/processor temperature and airflow, not just the temperature of the exhaust air [#19597387][#19597398] If the processor temperatures are the same, the new cooler is more efficient because it removes the same amount of heat with a smaller assembly [#19597398] A hotter exhaust can simply mean heat is being transferred out of the APU better, although some heat may be shifted to other parts of the console [#19603867] One reply notes that temperature does affect component life, especially capacitors, but the thread does not show that a 3–5°C higher exhaust temperature would definitely shorten the PS5’s lifespan [#19597420] So the forum’s practical conclusion is: judge the console by internal component temperatures and real behavior in games, not by heatsink size or exhaust-air temperature alone [#19597387][#19603867]

    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 ...

    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

    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

FAQ

TL;DR: PS5 CFI‑1116A shows 3–5°C hotter exhaust; "the processor that is cooled in both consoles is supposedly the same." Focus on CPU/APU temps and airflow, not heatsink size alone. [Elektroda, eraeste, post #19597378]

Why it matters: This FAQ helps PS5 buyers and owners decide whether to keep or return CFI‑1116A and understand its thermal changes.

Quick Facts

Is the PS5 CFI‑1116A worse than the launch model?

Not necessarily. The thread points to better APU cooling on CFI‑1116A, with warmer exhaust and some heat shift. "The new PS5 actually has better cooling because it removes the temperature from the APU much better, at the expense of radiating some of the heat to other elements." [Elektroda, bubu1769, post #19603867]

Does hotter exhaust air mean my PS5 runs hotter inside?

No. Hotter exhaust can indicate greater heat removal from components. "The more air flows through the heatsink, the more energy it will take away." Exhaust temperature alone does not define internal component temperatures. [Elektroda, bubu1769, post #19591302]

Will the smaller heatsink hurt game performance or frame rates?

Performance should be unchanged because "the processor that is cooled in both consoles is supposedly the same." Without higher CPU temperatures, there is no basis for slower frames. [Elektroda, eraeste, post #19597378]

Which temperatures matter most: CPU/APU, RAM, or SSD?

For stability and performance, CPU/APU temperature matters most. Shared captures in the thread show lower CPU on the new unit and higher RAM/SSD temperatures. Owners focus on CPU when judging throttling risk. [Elektroda, eraeste, post #19601694]

Why can a smaller heatsink still cool as well?

Cooling depends on more than size. "How much heat it is able to transmit 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." Active airflow can offset reduced fin mass. [Elektroda, bubu1769, post #19591409]

Should I return my CFI‑1116A for the older PS5?

Return only if the CPU runs hotter or the console misbehaves. "Until someone measures the temperatures on the processor itself, it will be a guess." If games run fine and noise is normal, keep it and monitor temps. [Elektroda, bubu1769, post #19597387]

What exactly changed between the launch heatsink and CFI‑1116A?

Reported changes: smaller heatsink, copper base reduced/removed, two heat pipes instead of four, and a revised fan with different blades and angle. These trade mass for airflow efficiency. [Elektroda, eraeste, post #19600306]

Could higher exhaust temperature reduce the console’s lifespan?

Heat accelerates wear, especially for capacitors. "Yes, temperature affects the service life of components, especially capacitors." Impact from a few degrees depends on whether heat stays in ducts or warms the whole interior. In power supplies, hot placements shorten capacitor life. [Elektroda, bubu1769, post #19597420]

Does the new fan spin faster, or is it just redesigned?

Design matters more than RPM. "Not so much faster as it is constructed in such a way that it pumps larger amounts of air." More airflow through fins removes more heat from the APU. [Elektroda, bubu1769, post #19591302]

How can I test whether my PS5 runs too hot?

Measure, don’t guess. "Until someone measures the temperatures on the processor itself, it will be a guess."
  1. Warm the console with a demanding game for 20–30 minutes.
  2. Record exhaust temperature at the rear with a probe or IR thermometer.
  3. Note stability and noise; repeat after cleaning vents for comparison. [Elektroda, bubu1769, post #19597387]

Which component does the PS5 heatsink primarily cool?

The main target is the APU (CPU+GPU). The revised design removes APU heat more effectively, while some heat radiates to nearby elements, like memory or surrounding boards. [Elektroda, bubu1769, post #19603867]

Is the CFI‑1116A louder or quieter than the original?

Noise depends on fan efficiency and control. "This could be remedied with a more efficient fan, but it would again increase the volume of the console." The revision aims to move air without adding noise. [Elektroda, bubu1769, post #19603867]

Does 230 W vs 220 W power draw mean anything important?

230 W is higher consumption than 220 W. The thread posed this example but did not include measured PS5 power data to compare revisions. [Elektroda, eraeste, post #19600306]

Did Sony fix coil whine in the new revision?

The thread notes some older units had coil whine. It does not tie coil noise to the heatsink change or confirm improvements for CFI‑1116A. Unit-to-unit variation remains possible. [Elektroda, eraeste, post #19591000]
