Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Yeah, given the sub-optimal internal design and thermal padding for the memory cooling, side panels with filtered cut-outs is one quick option, should it cause problems.
Probably gonna see those on the aftermarket.
Nice to hear Steve explaining exactly why the classic "thermal testing" consisting of thermal imaging of the outside of the box, seen on various websites, isn't particularly useful for determining the efficiency of the cooling design.
edit: overall not too worrying? There's always spinning the fan faster. As mentioned in the latter half of the video, the PS5 is currently whisper quiet under load, Sony left a lot more power budget for the fan to ramp up in the future. Still, quite the inefficient solution for these models in a scenario where cooling the RAM was the main issue and the fan has to ramp way up, brute forcing it, while cooling for the SoC itself seems quite efficient.
Very bad gddr6 temps, close to tjmax (100). Especially disappointing since they went all out on the SOC with liquid metal, but completely ignored the mem... I wonder if leaving the PS5 without the plates would mean a lot more dust getting in to the point of erasing that benefit.
I wonder how long it will be until we see water cooling kits for the PS5. I'm sure Linus will do a video with a janky setup soon!
Yikes, The memory temps being 93 *C at full load is concerning. The fan is currently not working at full power apparently. It can be much more powerful, but the sacrifice can be the loss of dead silence. Sony also has said that fan control will change with software updates.
Removing both the side panels also helps decrease the temps by a few degrees. Increasing the size of thermal pads would theoretically also help, maybe future units may have bigger ones since Sony has done a lot of revisions in the past of their hardware during production.
Overall, pretty disappointing.
It's not like.... morally bad for a computer to be hot. If they had a target spec and they hit it then it doesn't matter if it's hot. Like maybe if they cooled it they could overclock a few more mhz, but I'm sure they had a chart somewhere with "fans" on one axis and "mhz" on the other and picked the place the lines crossed or whatever. It's not bad to run hot if it hits the speed it's designed for at that temprature.
The ps5 side panels are trapping the heat inside and raising temperatures by 5-7c. Idk how can you design a computer casing in 2020 and not just cut 6-7 small holes on each side to let the air move

My choice to just wait for the Slim or whatever is making a lot more sense. I ASSUME it'll happen since there's a pattern of companies releasing the launch version with a glossy finish so it gets scratched up and smudgy so when they reveal the matte redesign, it looks cleaner by comparison and thus both seeming newer and appealing to people who might want to buy a second console.
Just going off of PS3->PS3 slim, Xbox One->Xbox One S, 3DS->3DS XL, DS LITE->DSi, PS4-PS4 Slim, Wii->Wii Mini.
The thermals seem fine on my console, my one gripe is that the optical drive is insanely loud when initially reading a game disc. It stops after a couple of minutes but it seems a common problem, I can live with it if Sony release an update that only reads a disc once after it's inserted.
Edit: here's a video of it.
...causing most of the PS5's issues...
What issues?
Why do you care if the RAM runs hot. It's not like you're going to get to overclock it. If it works it works. And it works.
Also cutting slats in the side would mean a more direct path for fan noise to get out and so make it louder. It also might be detrimental when it is lying down.
Modern cooling works on a thermal feedback loop. The system thus will usually 'run hot' because its running the fan as little as possible and still remain in the design thermal limits. If you add 5C to ambient it won't mean the memory overheats, it just means the fan will spin up a bit more (a bit more noisy).
