We finally know why the new PS5 model is lighter, and it’s not good news
Journalists and tinkerers have been able to get their hands on the “new” PS5 model which has been spotted recently in various retailers across the world, and which has been reported to be significantly lighter than the launch models.
What they found out is a bit concerning:
New PS5 Model lighter because of of smaller heat sink, concerns arise about overheating
Youtuber Austin Evans reports (video below) that the new PS5 model is 300g lighter because Sony has made the heat sink smaller. In his tests, the new PS5 is running significantly warmer (3°C or more) than the original model. This might not seem to be much, but as some testers mention, this could get much worse as heavier games demand more of the console in the future.
Additionally, as mentioned in Austin Evans’ video below, Sony have a history of their consoles overheating, so this move does not inspire confidence. It is clear that their engineering teams have concluded that a smaller heatsink will not dramatically impact performance or longevity of the console, and overall things should be “fine” with these new models. But it is unequivocally a “downgrade” of the PS5: you’re getting a lower quality product compared to the original models.

Is the new PS5 overheating, or actually better at dissipating heat?
Now, it is worth mentioning that the way Austin is measuring the heat on the PS5 is not extremely rigorous. As some people mentioned, just because the outside of the console is warmer doesn’t mean there’s any issue. Actually, it could mean the opposite, that the new model is better at dissipating heat. More heat outside = less heat on the CPU? Austin Evans disagrees:
Couple people mentioning higher exhaust temps COULD mean the cooler is doing a better job dissipating heat. The thing is, Sony removed a SIZABLE amount of the heatsink on this new model. With fewer fins and smaller heatpipes it simply isn’t as efficient at moving the heat out of the console.
Think about it as if it were a PC. If I remove a large CPU heatsink in favor of a smaller one the exhaust coming off my system would be hotter as the overall system temps are higher since the weaker cooler can’t cope. That’s exactly what’s going on here IMO.
Is the new PS5 model a sign that a PS5 slim is coming?
According to The Verge, such minor modifications of the PS5 could mean Sony are hard at work looking for ways to reduce the size and weight of the PS5, the heaviest and bulkiest console in recent memory.
Sony uses this heatsink to cool the PS5, and the console has a heat pipe with a shape and airflow that’s designed to create the same level of performance as a vapor chamber. The heatsink, hard copper plate, and aluminum dissipation fins all take up a significant amount of space inside the PS5, and contribute greatly to its overall size. It’s interesting to see Sony reduce the size of this part, and I’m hoping this could be the first sign of the company working towards a smaller PS5 model.
With concerns around this new revision of the PS5, more and more people on social media are saying they would now rather wait for a “Slim” version of the PS5, rather than buying a “downgraded” version of the current PS5.
Why did Sony remove parts of the heatsink in the new PS5?

Old PS5 model CFI-10 on he left, new model CFI-11 on the right Significant portions of the heatsink have been removed from newer PS5 models, possibly to save on copper costs during manufacturing
This new PS5 model has been seen in retailers in Australia, the UK, Japan, and the US. And there is no doubt that it will progressively replace the launch models in retailers as original inventory sells out worldwide. If you are concerned about getting one versus the other, this can be checked on the SKU number on the box. Older models got by CFI-10*, while newer “downgraded” models start with CFI-11*.
As to why Sony made that decision, it is pretty obvious. With copper price almost doubling in the past year, this was most likely a cost-cut decision, designed for Sony to not take a huge loss on their PS5 hardware. Sony recently announced they’re now making a profit on their PS5 hardware sale, and this manufacturing cost reduction will most likely help in this direction. Ironically, it seems that if you want to get the best bang for your bucks (or at least, give less of a margin to Sony), the digital edition of the PS5 is the way to go: they sell those at a loss.
That is, if you’re able to find a place that actually has PS5s to sell, of course.

Don’t be a sore loser man, he won
I’ll be a sore loser. It is the best kind of loser.
Y’all all are losers.
Jezus, this is so f@cking annoying. Can’t understand why moderators delete this ***.
I see people commenting and think they have something useful to say in which I can get some information. Please, mods, ban these idiots
Trying to be the first to say “First” is a Wololo tradition. Let’s not argue with tradition.
I just want coil whine and fan noises to be sorted out. These are so annoying, especially in graphic demanding games. Xbox doesn’t have such problems at all.
Coil whine wasn’t “repaired” in new SKU.
you really can’t compare this to a PC. a console is completely enclosed, and not designed to be opened by the user. airflow is obviously going to work differently. one might even argue potentially more-so efficient than any pre-built PC. or any PC with a standard level of cooling.
i suppose it could still be possible what people are mentioning… if it is hotter outside, then it is possible the system is doing a better job of moving that hot air OUT of the machine.
my reasoning on this goes based on a heatsink-to-fan ratio. so, basically… if a heatsink is SO big, then too small of a fan, or air flow, wouldn’t be very effective at cooling. if the fan can’t move away the air quickly, or efficiently enough, then it should stand to reason that the heatsink is just accumulating an excess of heat that just sits there. SO, not only would this be deficient in cooling the CPU but it would also increase ambient temperatures too.
i hope this line of thinking is making sense, or actually works.
all-in-all, i feel the new model warrants a more thorough heat test.
“It is clear that their engineering teams have concluded that a smaller heatsink will not dramatically impact (..) longevity of the console”
What is this based on? For the last decade or so, we have evidence Sony equated longevity of the console with that of a simple CR-2032 battery and did their best to make it a non-user replaceable part.(from some models you even need to remove the heat sink to replace it).
Again no mention of the fact that they are using a slightly smaller dye but are happy to say its not good news. *** you are talking about before writing an article
and 0 mention about WiFi 6e board.
Looks like the SSD manufacturers aren’t the only ones swapping components.
Kind of misinformation.
They reduced the size of it because the heatsink was overextending into where the RAM is, causing undue heat on the RAM.
Also; actually using Austin Evans as a valid source. Lol
