The New PS5 Models Have Smaller Heatsinks

Given that the PS5 already ran pretty hot, it’s not the best sign that the console’s latest revisions are shipping with smaller heatsinks than the original console.

Stock of the latest console has arrived in Australia and Japan, and one of the things we know it changed was the need for that annoying screw for the PS5’s stand. But teardowns of the new PS5 revisions have revealed that it’s not just the stand screw that has been changed.

A new video on the Austin Evans channel has torn down a brand new PS5, acquired from Japan, and an older existing model with all the original parts. Not only is the heatsink in the new PS5 revisions around 300 grams lighter than the original heatsink unit, but there’s also a lot less copper coverage and fewer fins, too.

Sony made some noise recently about how the PlayStation 5 is now profitable — although the Digital Edition is not — and one likely reason for that is reduced cost of materials. It’s worth noting that the internal fan for the PS5 appears to run a bit more smoothly and efficiently, but the difference between the two won’t be noticed in a regular living room setup (or if you’re wearing headphones).

What Evans’ teardown doesn’t reveal, sadly, is the impact of the changed cooling mechanism on the internal thermals. An analysis by Gamers Nexus did this when the PS5 launched, although it took a substantial amount of time and custom wiring to get proper temperature readings on the memory and different points on the PS5’s SOC. Evans’ video did capture the external temperature of the PS5’s exhaust, however, revealing an increase of about 3 degrees with the new model.

One of the concerns with the original PS5’s cooling setup was the fact that the bottom memory module ran surprisingly hot, hitting around 94 degrees Celcius when at load — and that wasn’t with the console in a TV cabinet, but in a well ventilated room. One option there was to run the PS5 without either of the side panels connected, as this helped drop temperatures by about 5 to 6 degrees. That’s especially worth thinking about if you’re in Australia and your PS5 is in a more enclosed unit. (Besides, removing the panels won’t just help ventilate the console — it’ll make it easier to fit in tighter TV cabinets, since you won’t have to deal with those space-age curves.)

Most regions are only just starting to get the new PS5 revision, so it’ll be a little while before we start to see more in-depth tests and breakdowns of the new PS5 under load. There’s no reason to believe that the console will suffer from any problems that the original console didn’t have, so don’t panic if you were thinking of pulling the trigger on the PS5. But it’s still interesting seeing just how much weight and surface area Sony shaved off here. And I’m curious: just how much do copper heatsinks cost to manufacture these days? If you know anything about that side of the industry, please get in touch!

  • Gotta say as soon as i picked my new one up the other day i could tell the weight difference immediately just from holding the box.
    TBH i dont think that it’s a bad thing because the console is so damn heavy.

  • Thanks for providing the actual pertinent info in the headline, Alex. I saw the video in question appear in my recommended vids and chose not to watch it out of principle because of its irritating clickbait title.

  • Leaving my final judgement until someone like GN does a proper analysis, but I can’t see how dropping 350g or so of thermal mass is going to help this out any. It does have that new fan though, maybe its better? I’m probably more intrigued if this has any effect on performance on any of those games that have issue hitting locked fps targets due to the dynamic nature of the system.

  • All these articles about this are just recycling the same story over and over, why don’t you do some actual journalism here instead of just going for a easy recycled story that is days old anyway and test the actual on chip temps of a new and old so we can compare, this info here pretty useless to someone about to buy a ps5.

      • yet I imagine if you asked – someone with the new model would assist with loaning it out, knowing it would be disassembled for testing and they would be reimbursed should any damage come to it.

        The quality and depth of articles on here has gone so shallow I only check on here for ‘news’ once a month or so.

  • Zero concern about this – exhaust temps may be a proxy for internal temps but not a great one. 3 degrees hotter at the exhaust only tells you that the vented air is hotter.

    The interesting thing to me is that the heat pipes are much longer in the new revision, and that single long heatsink is longer than the original one. More fins and simpler airflow?

    Anyway, I don’t have a choice, mine’s on the way sometime whenever whatever however it gets to my local store, and I’ll be chuffed either way – my PS4 pro is back to making a fighter jet at an airshow sound like a calm breeze… so I look forward to anything quieter than that.
