If you’ve been following the PS5 since launch, you’ve probably heard the whispers. The rumors. The urban legends about liquid metal supposedly leaking inside consoles, turning Sony’s flagship gaming machine into an expensive paperweight. Well, console modder and repair specialist “Modyfikator89” just uncovered something interesting that might put those fears to rest.
The latest PS5 Slim models are packing a redesigned cooling solution that changes how liquid metal is applied to the CPU, and it’s a upgrade that Sony borrowed from the PS5 Pro.
The new cooling design, what’s different?
Here’s where things get technical, but stick with me because it’s actually pretty clever. The newest PS5 Slim variant (model CFI-2116) no longer uses liquid metal applied directly onto the processor like previous models. Instead, Sony integrated a grooved component that creates a specific pattern, guiding the liquid metal to distribute more evenly across the CPU surface.
Think of it like the difference between pouring syrup randomly on pancakes versus having built-in channels that spread it perfectly. Same concept, better execution.
According to Modyfikator89’s findings shared on X, this design was originally developed for the PS5 Pro. But now Sony has rolled it out to the standard Slim line, meaning both the disc and digital editions benefit from this improved thermal management system. It’s not often that premium features trickle down to standard models this quickly, so props to Sony for that.
MASSIVE PS5 NEWS! SONY’S SILENT HARDWARE UPGRADE!
The MOST important hardware update of the year is here!
Sony has quietly updated all new PlayStation 5 Slim consoles (model CFI-2116) — both Disc and Digital Editions — with an ALL-NEW cooling system! 🔥

The liquid metal controversy explained
Let’s rewind for a second. A few years back, social media exploded with reports claiming that PS5 consoles were suffering catastrophic failures due to liquid metal leakage. Repair shops posted images of units with internal spillage, and suddenly everyone was convinced that keeping your PS5 vertical was a death sentence.
The theory went like this: gravity would cause the liquid metal to pool on one side over time. Heat cycles would weaken the seal. Eventually, you’d have liquid metal seeping into places it absolutely shouldn’t be. Physics made it sound plausible. Fear made it spread like wildfire.
But here’s the thing, those reports were never conclusive. Most of the damaged units had been previously opened by users or third-party repair services. There was no way to verify whether improper handling during those modifications caused the issues, not the console’s design itself. The whole thing became one of gaming’s modern urban legends, right up there with blowing on cartridges to make them work.
Still, perception matters. And if players are genuinely worried about their $500 investment turning into a ticking time bomb, that’s a problem Sony needed to address.
A smart evolution, not an admission
This new grooved design isn’t Sony admitting the old method was flawed, it’s simply smart engineering evolution. Console manufacturers constantly refine their hardware between revisions to improve efficiency, reduce costs, and yes, enhance reliability.
Gaming hardware generates serious heat. Modern CPUs and GPUs push enough watts to rival small space heaters, and keeping temperatures in check is crucial for performance and longevity. Liquid metal remains one of the most effective thermal interface materials available, offering better heat transfer than traditional thermal paste.
What Sony did here is take an already effective solution and make it even better through improved distribution mechanics. It’s the kind of incremental innovation that might not make headlines, but definitely makes a difference in the long run.
What this means for PS5 owners
Should you worry about your current PS5? Short answer: No. If you’ve had your PS5 for years without issues, the liquid metal is doing its job just fine. The horror stories were always outliers, often involving units that had been tampered with. Normal use, whether you keep your console vertical or horizontal, won’t cause liquid metal to spontaneously escape and destroy your system.
That said, if you’re in the market for a new PS5 Slim, knowing that the latest models have this improved cooling design is a nice bonus. It’s one less thing to worry about, even if the worry was mostly unfounded to begin with.
Console hardware evolves quietly in the background while we’re busy actually playing games. Sony’s decision to bring the PS5 Pro’s cooling innovation to the standard Slim models shows they’re paying attention to both engineering improvements and user concerns, even the irrational ones.
Whether you’re a hardware enthusiast who loves tearing down consoles or just someone who wants their PS5 to last through this generation and beyond, this is good news. Better thermal management means better performance, longer lifespan, and maybe most importantly, peace of mind.
