But I feel the redesign is just that, it's not running worse. But he himself implies that. And the kingthrash video kind of shows his bias in how he talks about specific products.
I haven't seen the KingThrash video and I have reservations over some of their own gaming coverage tbh, but I will give it a watch to see what they point out. They've brought up some points in some other videos that I agreed with, even if they've done videos where there were main points I definitely didn't agree with at all.
Austin should take the criticism since many notible sources with engineering background say otherwise to Austin's claims.
I mean I saw the Gamers Nexus stuff, but I don't think they were outright saying Austin was wrong. Just that it would be impossible to determine if the thermals are indeed hotter due to the system running hotter doing what Austin did, because that would not be enough to make an actual judgement call.
And on that note they are absolutely correct. But something else I think which got lost is the fact that Austin was never testing for thermals in the first place; his goal was to find out why the PS5 was half a pound lighter. In hindsight maybe he should've not emphasized the thermals as much but if you realize the heatsink is reduced significantly in size, has material changed, and the exhaust in the back is hotter, you're prob gonna draw a correlation and assume the system might be running hotter.
..especially because the fan, while a different model, at least from the onset could not be determined as running any faster or cooler (actually fans don't run cool at all, they just redistribute air at the intake temperature elsewhere throughout a design's cooling pipeline. It's the speed in which the fans operate that give the sensation of them producing cooler air and I think it was noted in the video that the fan seemed to not be any louder but again as you say, it's a different fan model).
So no, Austin can stay being wrong. And he playing victim is typical of someone who gets called out.
But if he has in fact gotten doxxed and death threats, etc., how is that playing victim to speak up on it? Let us say he is 1000% wrong, does that still deserve one to be doxxed, harassed, threatened etc. over that wrong opinion?
Austin Evans Defends His PS5 Revision Video
I mean, he is defending his stance and trying to justify it amid the backlash, which is noble. He shouldn't feel forced to change his opinion over groupthink or peer pressure, if he genuinely feels he's right about it.
If folks like DF and Gamers Nexus do a more thorough analysis and notice that internal thermals are still as good or even better (lower) than the launch PS5, and if Austin is genuine, then he'll walk back his hypothesis ("If the heatpipe is reduced and exhaust temps are hotter, then the PS5 revision must be worst") and change his opinion.
I'd much rather him do so guided by trusted and verifiable data versus a legion of salty fanboys using terror tactics to force it on them.
his clearly correct, anyone who thinks a reduced heatsink does not make the system run hotter is legit braindead and basically a science denier...
it's very simple, less material = less surface area to dissipate the heat off of the SoC = hotter running components
simple physics you can't disprove because you would literally break the laws of physics in order for this system to run at the same temperature as the original model
but it's not surprising to see fanboys demonstrating once again how retarded they are
There is actually TWO scenarios where the new PS5 indeed runs cooler even with the reduced heat pipe and likelihood of the fan running at same speed despite a model change.
The first is that Sony over-engineered the cooling system. But if so, that actually reflects badly on them and shows engineering incompetence as a division, that perhaps the design was in fact rushed in some parts in terms of the system build itself. And, there were already rumors suggesting this going back to early last year. I don't know how this scenario reflects well on Sony outside of a "hey, they FINALLY engineered the system properly" sort of way, because otherwise they just wasted hundreds of millions of dollars on materials they didn't need, and if they could've saved those costs, it's possible they might've, just as an example, NOT increase costs of 1P games by $10.
That's a correlation on my own end with no evidence to tie them, mind, but it's meant to serve as an example. Anyway, the 2nd possibility is that they've moved to the N6 process at TSMC. AMD are bringing new Zen chips on N6 later this year I think, and there were already some rumors going around about Sony securing N6 fabbing at TSMC (well, that would be AMD's doing, for Sony as their client).
However this one seems less likely because any switch to N6 for PS5 SoC production wasn't said to happen until around mid-2022, and it's obviously too early for that with the new revision. Unless Sony bumped that all up ahead, but we'd of heard some actual news come out about this if that were the case. And even if so, if you remember Gamers Nexus's older video, the point of potential concern with the system wasn't the SoC, but the GDDR6 memory chips.
A switch to N6 process for the SoC would theoretically help reduce some of the power consumption for that component which could be redistributed to cool the memory chips, but this only matters if the big issue WRT that in the launch model (IIRC, either the fan, heat pipe or both not actually covering a couple of the modules). TBF Austin's video didn't ive a detailed look at the new system's PCB and some components might've been rearranged, so we're going to have to wait on those Digtal Foundry/Gamers Nexus/SpawnWave etc. deeper looks to see what's really going on here.
That would hold true if the fan design wasn't different and the newer model being actually quite.
Which means the fan and heatsink are effective enough.
Until we see more raw data, it's his assumption.
If your theory was correct why are reference cards cooling fine as apposed to AIB which have larger heatsinks, larger fans?
For the longest time they were loud but blower style got the job done on GPU'S and cooled just as well as AIB. They were just louder because they had one fan instead of 2-3.
The thing with GPU cards tho is that they go into devices, PCs, that are built much differently than consoles. There is usually a lot of open space in tower PCs housing powerful GPUs (not to mention other things like liquid cooling) which naturally creates a space for cooler air to exist to circulate in the design because there is more volume.
Consoles are not built this way. They don't have liquid coolers to compliment their fans and components are very tightly packed in close to each other, with very little room between the components. Without that extra room, there is less existent volume to let the heat spread out and naturally cool off, which means the air the fans blow around will be that much hotter.
Some people are under the misguided belief that fans produce cooler air but they don't; they simply blow around the air at the temperature of the surrounding environment. Even speeding up the spin of the fan blades does little to change that, and all of this is magnified if the an is in a confined space (like the innards of a game console). The only way you factor in genuinely cooler air is with either much greater volume of space for the heat to dissipate into (and cool off that way), or using something like an air conditioner or liquid cooling (if talking electronics).
A thermoelectric peltier plate is another option and size-wise would fit a console, but costs way too much power/wattage and only pertains to a small surface area like a specific chip component or two. And you'd need something to deal with removing the heat generated on the opposite end anyway.
