As I wrote, you will probably get less than 9.6 Gbps in most rooms due to interferences of other WiFi devices.

I'm sure if Sony wants a wireless VR solution via WiFi 6, they want it to run flawlessly for the majority of PSVR users... so they won't expect 9 Gbps or even 8 Gbps, probably more in the 6 - 7 Gbps area to be on the safe site. And to avoid latency issues, sending an uncompressed video to the headset would be preferable.

For PSVR1 games that would be fine, since an uncompressed 1920x1080 video with 8-bit per color + 120 Hz only needs 6 Gb/s. Even a HDR 1920x1080 video with 10-bit per color + 120 Hz could still work in some rooms (but could already problematic in other rooms:

It would be nice if Sony maxed out PSVR1 games on PS5. Some of them are sub-1080p on PS4 Pro and most of them are under 120 Hz. With additional rendering in higher resolutions and then downsampling to 1920x1080 (this resolution scaling is already supported by SteamVR and improves the image quality) the improvements could be huge, even with a PSVR1 connected to the PS5.

But what improvements would PSVR2 have over PSVR1 on PS5? Obviously a panel with higher resolution would be the biggest improvement for the image quality... This would also allow a bigger field of view without a worse pixel density. And I hope that Sony stays at 120 Hz and adds HDR 10-bit for VR games.

Depending on the resolution bump of the headset-panel WiFi 6 wouldn't be fast enough in most cases:

So if a cable means much better image quality compared to wireless compromises, I stay wired.

That's the thing with Liquid Metal. It acts kinda like a liquid. That's why for laptop overclockers who want to really do LM on their laptops, they have to contain any potential spills by applying a electrical tape barrier or a foam barrier. For PS5, there's only going to be a small percentage of users that will be moving this around. It's not a portable laptop. And even if they do, it seems that Sony created barrier around it. Only time will tell if it was designed well but that can be a potential point of failure if not handled properly. Spills happening in a properly applied LM is very small.

If Sony allow PSVR2 to be used wired for maximum performance and on battery with degraded one I certainly would prefer to be on the first, but would be good to have options anyway.

I wonder if they could use multiple I/O channels, if they are outputting separate streams for each eye anyways?
That could use the USB connections while leaving WiFi free (or possibly just for tracking info, video being on 1-way channels)

I have the normal launch PS4. And You just need a phillips head and a T8 Torx screwdriver. Just remove the top 3 back Torx and the bottom Torx, slide off the hard drive and remove every screw you see. 

And just keep removing stuff until you get to the motherboard and flip it around to find the SoC, and you'll see 'probably' some dried out thermal paste that's barely even there anymore, and re-apply and do everything in reverse.

alot of people bring up the thermal paste but the majority of cases it's the heat sink that's the problem. Make sure you check the heat sink for dust build up. Because i had replaced my thermal paste and issue wasn;t resolved till i vacuumed it all out. Mine went from sounding like a plane taking off, to a sleeping baby. 

do you want a link on how to clean the heat sink from dust? tlou2 will be quit to play on like mine. 

I don't know of any somewhat recent console over the last couple gens that requires anything other than pulling off stickers, popping plastic apart, or unscrewing. If you're doing something else, you're missing something.

My 1200 PS4, was extremely clean inside, and new MX-4 thermal paste only helped a little bit. I honestly think the problem is the contact between the APU and heatsink. I've recently seen a vid where a modder shows how convex their PS4 Pro APU is, which leads to only a small amount of heatsink contact in the very center of the APU. The paste can only do so much and requires fairly snug contact across the entire chip to be efficient. I never looked that close at the time, but I can't think of anything else other than possibly a poorly binned chip that unfortunately runs hotter, and there's little you could do about that.

What I eventually did was purchase a fan (accelerator) adjuster, which easily plugs into the fan and mobo, where I can set the speed at which I want the fan to run most of the time. My PS4 fan now runs around 40% of it's total RPM the overwhelming majority of the time, and only when the system get's quite hot, does the fan adjuster allow the PS4 to take over and ramp the fan up even more so (50% ish) for a short period to bring the temp back down. Once the temp drops enough, the fan adjuster takes over again and keeps the fan at 40%. It's more noisy than letting it run at stock 20% or 30%, but the 40% RPM consistency makes it much more palatable while remaining reasonably quiet. Once you get over 50% it starts to get annoying, and more so as you go up beyond that.

Since the PS5 has a surround barrier designed to hold in the liquid metal, a little pool of it should help alleviate any convex or concave chip or heatsink issues, while still having great thermal transfer efficiency. As long as it works as intended and keeps the liquid metal safely inside, which based on it's conductive properties and multiple years of design and testing, SNY would be crazy to use it if they weren't sure it was foolproof.

Tempted to open up my PS4 and do this. I have a can of compressed air and some Thermalright TFX paste which when applied, should give much better thermals and lower noise. Only thing is, I have my PS5 coming soon so the PS4 will be relegated to a legacy console in my collection lol

so you never got to your heat sink?? As for the ps5, it should be pretty cool, but we don't know how extreme the apu gets since its overclocked all the time, so all that cooling is necessary. But the chief engineer did say in an interview, that generally the ps5 runs quieter than ps4. Whether or not the fan spikes during high iintensive games, we will find out. My room is well ventialted, ps4 stays quiet, also have an ac to keep the room cool during summer.
