The heatsink and fan are absolutely massive, the only other remotely large component of the thing is the PSU, so either they were having trouble or they way oversized them to not get any trouble in the future.
Especially since there's no filter anywhere, so all the dust is going to get sucked straight and will be clogging up those heatsinks pretty fast.
he does mention the 2 dust catchers and that you can vacuum them.
by the way, if you've seen console repairs - haven't done any myself since many years - you'll remember the huge amount of dust they suck in. Being able to vacuum that is a big big win for the longevity of the device
EDIT: just noticed at the end the disclaimer about the dust catcher :) I mean, they still need to be covered from a legal point of view
It is also the use of liquid metal - how will that hold up past two years or so warranty period on your thermals on top of the other grease and crime of today's air that will build-up overtime. Probably all be fine for a couple of years/warranty period though and even then, does seem well serviceable design wise - though how far you can service outside warranty without Sony limitations will be the crux with all manufacturer hardware. But servicing any paste/clean-down does from the ease in the video seem to be within the reach of many due to the lack of any special tooling, let alone any hot glue gun shenanigan. Also mindful how they made the side panels very user accessible, so maybe custom side-panels will be a market opening up more there - which is a nice touch. Though I'd imagine it may become a thing that running with the panels of makes it better akin to how people are with dust covers upon speakers.
Though as with all first gen new consoles, they do tend to sit on the edge needing large cooling systems and then a couple of years later a revised (die shrink) update comes along and is now cooler, less power hungry, cheaper to make....same old story. I also expect by then the need and use of liquid metal will be removed as that won't be cheap cost wise either over conventional pastes/pads.
Still, makes you wonder if the blue-ray drive with that shielding is more additional heat-sink and be interesting in seeing the temperature of a disc before and after playing for an hour. But then, you just don't get those kinda things done in testing
They have two dust traps with dedicated holes to vacuum out - covered in the video.
