Sony patented cooling solution - likely for ps5

Eutectic liquid metal type paste so there is better heat transfer and more consistent than thermal paste.

One of the ps4 pro issues was early models were very loud, some later models were much quieter, variations in heat trasnfer needed to be solved for faster ps5

Liquid Metal degrade pretty fast and then you have to replace it. Also Gallium is pretty non friendly for solder, Aluminium and I don't think that it's going to be in IT sector used on mass production level. Sure patents can be done, becuase why not.

Mentions Ga, In or Sn or eutectric between them, also you can Ni coat the Al.


But who knows, something is up for this stuff to pop up before teardown.

Maybe Sony have solved the issues of using this tech, hence the patent.

I thought a little Mark Cerny was getting shipped inside each one to blow on it when it got hot

I just want the teardown tbh - I'm not going to feel confident with a heatsink and a sheet of liquid metal. Probably the two pertinent parts are what problems does it solve, and whether these are generalised semiconductor issues or specific to the semiconductor used by Sony. It sounds interesting though from a purely tech point of view. Sounds like it changes state so there will be questions raised around brittleness as well. As with anything like this, the innovation looks cool it's all in the delivery when it's first generation at scale. Definitely taking a chance, but I'm surprised they wouldn't have pre-tested with the last iteration of the PS4 PRo SKU's for example. Just to make sure the process works at this level and get some early indicators.

 However, when the amount of heat generated by the semiconductor chip increases, it becomes difficult to sufficiently cool the semiconductor chip due to the thermal resistance of the grease. In the semiconductor device of Patent Document 2, instead of grease, a metal that is liquefied by heat during operation of the semiconductor chip is used as a heat conductive material between the semiconductor chip and the radiator. When such a metal is used, the thermal resistance between the semiconductor chip and the radiator is lowered, and the cooling performance of the semiconductor chip can be improved.

 In a structure in which a fluid metal is used as a heat conductive material, it is possible to limit the range in which the heat conductive material spreads even when the semiconductor device changes its posture or vibrates in order to sufficiently exert its cooling performance. is important. Further, it is important that the force sufficiently acts on the semiconductor chip when the radiator is pressed against the semiconductor chip. That is, the adhesion between the semiconductor chip and the radiator is also important.

Yup, mine is still dead silent, I think it's dependent from were did you get that console, heard there are like 20 factories around the world. Mine is the second revision, bought it in November 2016:




The flash makes it too dirty. :lollipop_downcast_sweat: Well, never cleaned it before.

Uhu :lollipop_Mr_Smith:

Now boot up God of War (2018) and look at the map. Now make the same video.
My PS4 pro tries to cool itself by begging for a glass of water, but I refuse. Silly console, I'm not its slave.

Never seen any noisy PS4 before, I think the lineup we get is probably a good one. It's said that there are like 20 of those, and of course each should be pointed at some markets.

If you seriously need that God of War video, I'll try to make one for you if you don't believe me.

My launch bPS4 was a jet engine, as were my friend's, with any game, Uncharted 4 and GOW made it scream so loud that I stopped playing them, now I have a ps4 slim and I couldn't be happier that thing is dead silent even under very hot weather.

I believe all the claims, but it's strange that more than 100 PS4's I've seen all of them are extremely quite, some are full of dust and in shitty situations as well. I think it's a matter of where your PS4/Pro/Slim was assembled, this can't be all luck what we got here. The only noisy one I found is my sister's base PS4 it's so noisy that's unbearable, and it's actually from early gray market, US model PS4's! So it only solidifies my theory.

Liquid metal thermal paste has a very short life, compared to regular stuff, and goes bad after time (As demonstrated by several PC builders on YT).

I'll assume, and hope, this is a special new type.

It was patent dated yesterday - the patent obviusly solves the issue with eutectic pastes thats why it has been patented. Sony will have engineered this to death to base 120 million units off.

OK Sony I see you. Using that Thermal Grizzly eh shordy! :pie_roffles: :messenger_fire:

Could be that Eutectic, could be a Japanese supplier or other, we dont know the supplier or the make up of the Ga, In and Sn in the alloy.

The patent is about how they enclose and asssemble the solution on the board. Getting an extra 400 MHz is not to be sniffed at, imagine PC space to follow.

What Bo_Hazem Bo_Hazem is not telling us is the fact that he is living in Siberia.
Opening the windows for 5 seconds keeps the PS4 cool for a day.

Nah, I live here, temperature is considered hot in general: :messenger_winking_tongue:

But I usually have the AC on, so room temperature is usually around 23-25C.

And you're from Austria! It's like living in a freezer.🥶

Then you must not be able to hear the PS4 due to the sandstorms 🤔

Nah, Austria is pretty warm these days. Especially in summer.
We have 25°C just right now. Top Summer temperatures can reach from 35 to 40°C

Maybe you need to invest in a good AC, GREE is a great one ;) Here it's very rare to see something beyond 33-35C max, and now it's one of the best seasons. I still believe it's a matter of factory assembly, some factories might be fucked up or lack enough quality control.

It's sub-tropical.

As it's still warm in winter we get plenty of tourists from Germany, Denmark, and other cold countries. They catch up some tan to brag about it when they head back home. :messenger_winking_tongue:

....it is so simple, but yet so true.

Reading is hard, today is 14th august, yesterday was when exactly ?

.... and when was the patent filed?

Priority date (day.month.year)
04.02.2019

We've been seeing this posted for more then a year. I still don't see any evidence its related to PS5.

Isn't that only talking about the thermal paste and not the cooling per se? It doesn't seem like liquid cooling at all

What does it mean , liquid metal colling ? Is it better that the normal one , like in series X ?

Liquid Metal cooling refers to a thermally conductive compound that would theoretically replace traditional thermal paste. It is significantly more thermally conductive than pastes, but generally has trouble staying in place. Its very effective, but its use cases are rather limited because it tends to leak out from between the cpu and the cooler and fry the motherboard. If they have an effective system for using and containing liquid metal to these problems, it'll mean a significantly more effective cooling solution than XBox Series X regardless of its thermal solution. A system that uses liquid metal generally has a 5-10 degree cooling advantage over paste and even more than that over thermal pads.


Edit: To be clear, if they use liquid metal without a perfect solution for containing it, they'll have hardware problems similar in scope to the 360's RRoD. With that said, I'd love to see liquid metal cooling used effectively in a system like this. They performance gains would be huge. I don't expect anyone to use liquid metal for cooling in a mainstream product at this time.
