This claims based on simple understanding of Gravity. Liquid metal can move around and if there is no seal or its damaged/installed incorrectly during disassembly/assembly by user, then it can leak out to the motherboard and short circuit some of the components on it, leading to damage, because liquid metal obviously conductive.

It was designed and made to be used in vertical position by Sony, I am pretty sure a lot of tests were conducted, there is a proper seal between APU and Heatsink.

There might be issues when console was not assembled correctly at the factory. Nobody opens their consoles when they encounter issues to verify and confirm what caused a unit to malfunction. People simply send them to Sony under warranty or return them back to the store to get replacement there so the store will send the unit back to the manufacturer if customer claims that the console is not working properly.

Usually it happens right away after end user receives the unit. There is no supporting data on how many consoles were replaced due to this specific issue. If there was more data available or reasonable tests were conducted by third party, I am pretty sure that there would be a class action lawsuit or whatever it’s called.

Due to the console being so new and no data available, no adequate tests were conducted, reasonable return policies from Sony and stores, not that many reports of this specific issues, I assume that those claims are Bullshit and someone just wrote a controversial article to pay their rent.

Many people in PC building community use liquid metal on a high performance CPU that run hot. All of their motherboards situated vertically inside their cases. They use and build the seal on their own using multitude of different components, and still have successful results. Assuming that a big company who already released 30 million units didn’t performed and developed proper testing does not align with logic.

I could probably write a controversial article myself about any component inside the PS5, like it’s SSD:

After certain amount of read and writes, any SSD will eventually stop working, due to the SSD being imbedded to the motherboard, replacement is not possible in the normal consumer setting. Does Sony provide an option to run operating system on the external M.2 NVME drive for the console to function? No! This is a major flaw that Sony missed, make sure you don’t download/upload too many things on your PS5 drive or you can damage it.

Here, I did it. Obviously there is measures that Sony did with this specific drive for durability, but nobody going to talk about those, how can I pay my rent if I don’t write a controversial topic?

Until there is more data available, tests performed etc. I can tell you all this claims don’t have solid ground. Only after 5-8 years we will be certain about this generation durability.
