PS5 Thermal Paste (a.k.a. Liquid Metal): What’s the Deal?

If your PlayStation 5 has been acting up – loud fans like a jet, overheating messages, mid-game crashes – it might not be you. It could be the slimy “thermal paste” (actually a liquid-metal alloy) between the chip and heatsink calling it quits. Unlike older consoles that use basic gray paste, PS5s use a liquid-metal blend to move heat much more efficiently. Great news for performance, but it also means caring for it is trickier than slapping on old-school paste.

Over time this liquid metal can oxidize or drift away from the chip, especially if the console gets moved around or kept vertical for ages.

PS5 Is Having a Melt-Down (Literally)

When your PS5 runs hotter than your ex’s Instagram stories, it’s probably begging for a liquid-metal intervention.


Signs Your PS5’s Heat Pasta Needs a Refresh

You can’t ask the PS5 politely to check its temperature, so listen to these clues:

Overheat warnings: If your PS5 starts yelling “System is too hot” or crashes, that goo isn’t doing its job.
Jet-engine fans: If the fan is roaring nonstop, the console is struggling to cool itself.
Random glitches or slowdowns: Screen tear, frame stutter, freezing – heat-throttling might be to blame.
Spontaneous shutdowns: If it powers off during intense gameplay, it’s likely thermal trouble.

If you’re ticking these boxes, your PS5 might be “well done” on the inside.


Why Vertical vs. Flat Orientation Matters (Maybe)

Here’s the controversy: Standing up your PS5 might invite trouble that lying it flat avoids.

In a horizontal position, the liquid metal usually stays evenly between chip and heatsink – gravity isn’t pulling it off course. But when the PS5 stands upright for long periods, any tiny break in the foam seal can let the liquid metal “pool” downward.

Repair techs have found consoles (never opened by users) with noticeable pools of liquid metal at the bottom of the chip after years standing vertical. In some cases, enough metal dripped onto the board to short components.

Sony officially says either orientation is fine, and millions of PS5s have safely stood tall. The viral “PS5 melt-down” story was mostly a misinterpreted report. But many experts now err on the side of caution: horizontal is safer. If you prefer vertical, just be gentle with your console and keep it cool.

Even if rare, a full liquid-metal leak is scary. It only occurs if the seal was already compromised, but it proves a leak can occur.


All PS5 Models Use Liquid Metal

Every PS5 – Disc, Digital, Slim, or future Pro – uses liquid metal for cooling. No PS5 model is immune to oxidation, dry spots, or seepage if conditions aren’t ideal.


Keep Your PS5 Cool (and Happy)

Since you can’t just lovingly massage the metal back into place, prevention is key.

  • Airflow matters. Don’t cram the PS5 into a tight bookshelf. Give it a few inches of breathing room.
  • Dust it. Clean vents equal cooler temps.
  • Be gentle. Drops or impacts can damage the foam seal and encourage leaks.
  • Watch room temperature. Avoid hot, enclosed entertainment centers.
  • Horizontal is safest. If you want the most peace of mind, lay it flat.

If despite all this your PS5 is still misbehaving, it’s probably time for a professional thermal refresh.

Heat Pasta Drama

If your PS5 sounds like it’s auditioning for a jet-engine documentary, congrats — your liquid metal just filed for divorce.


DIY or Let an Expert Save the Day?

Replacing PS5 liquid metal isn’t a quick hobby project. The console has to be fully disassembled, old liquid metal removed, surfaces cleaned, and fresh metal applied correctly. A bad application can permanently damage the board.

If you’re not a console surgeon, seriously consider a pro tech.

TL;DR – Keep Your PS5 Chill

The PS5’s liquid metal is amazing for performance but high-maintenance. Watch for overheating signs, keep airflow clear, and consider keeping the console horizontal. If things still get spicy, a professional thermal refresh can save your console (and your sanity).
