Sony Quietly Changed the PS5 Slim Again. Here's What's Different Inside.

The short version

• A new PS5 Slim revision is shipping, built on a motherboard labelled EDM-051.
• It brings a PS5 Pro-style liquid metal cooling setup, a new heatsink and an easy-to-swap CR2032 clock battery.
• It turned up inside the Marvel's Wolverine Limited Edition PS5 ($649.99), which went on sale September 15.
• Sony hasn't announced it. Everything here comes from one technician's teardown.

Who found it

Console repair technician Modyfikator89 opened a Wolverine Limited Edition unit and posted the findings on X, calling it "not just another cosmetic revision." The included manual hasn't been updated to match, which suggests Sony rolled the change into production without any fanfare.

That isn't unusual. Console makers revise internals mid-generation all the time, often without saying anything.

What changed

According to the teardown:

• New EDM-051 motherboard with a simpler layout.
• Liquid metal cooling, with a containment design that resembles the PS5 Pro's. Liquid metal is a better heat conductor than regular thermal paste, but it has to be sealed in well because it conducts electricity too.
• A different heatsink, built differently from earlier Slim revisions.
• A user-replaceable CR2032 coin battery. This small battery keeps the console's clock running when it's unplugged.
• A newer, cheaper HDMI chip (the retimer that cleans up the video signal).

Why it matters, on paper

The battery is the change long-term owners will care about most. Coin cells wear out after years. A standard, swappable one means replacing it is a cheap fix rather than a repair job. The cooling changes point the same way: a console built to keep running for longer.

What we can't tell you is how it compares in noise or temperatures. Nobody has published proper testing yet, and we haven't had one in hand.

Can you tell which one you're buying?

Not easily. There's no new model number or box marking we know of, and the board is only visible once the console is opened. For now, the Wolverine Limited Edition is the one model confirmed to carry it.

What to watch: whether this board spreads to the regular Slim models, and whether anyone publishes temperature tests. Base PS5 owners have also had a software upgrade this month; our QSSR post covers it.
