This one came in hot. Literally. Thermal throttling warnings on startup, fan screaming like a banshee, and the customer said it was shutting itself down mid-game. Classic PS3 thermal failure.

Now, here’s where PS3s get interesting — and where a lot of people panic.

The Delid Problem

PS3 consoles are notorious in the repair community for one reason: to properly replace the thermal paste on the CPU and GPU, you sometimes need to delid the chips. That means carefully peeling off the IHS (the integrated heat spreader — basically the metal cap on top of the processor) and replacing the paste underneath.

Sounds simple. It’s not. If you slip, you can destroy the die. If the adhesive is old and brittle, it can crack. One mistake and you’ve got a £200+ motherboard in your hands that’s now a paperweight. That’s why a lot of shops won’t touch it. That’s also why it costs money when they do.

But here’s the thing — not every PS3 needs that level of surgery. Some do. Some don’t.

This was the state of the CPU and GPU. This PS3 had been nought secondhand, so it’s history was unknown. It appears this is the whote factory thermal paste – missing and very dried out.

This One Got Lucky

This particular PS3 didn’t. We didn’t need to delid it.

The thermal paste on the readily accessible areas was absolutely destroyed — basically concrete. Years of dust buildup, thermal cycles, and general neglect had turned it into a solid crust. But the underlying issue wasn’t buried deep; it was just blocked.

So we did it the straightforward way: full internal clean, every corner, every vent, every heatsink channel cleared of dust. New thermal paste on the chips (on the accessible surfaces). Cleaned the fan, tested it, checked the thermal circuit. Reassembled carefully.

The Result

Temps down. Throttling gone. Fan’s actually quiet now instead of screaming. The customer gets their PS3 back, and we didn’t have to do risky microsurgery to make it happen.

Why This Matters

Here’s what people don’t realize: dust is the enemy of every console. It blocks airflow, traps heat, and forces the fan to work harder. The harder the fan works, the more heat it generates (counterintuitively). Eventually the console gets hot enough that it throttles performance to protect itself. Then it gets hotter. Then it shuts down.

Thermal paste is just part of the equation. Yes, it dries out over time and needs replacing. But 80% of the time, a PS3 that’s overheating is actually just suffocating under dust. Clean it out, renew the paste where you can safely access it, and suddenly it runs like it’s supposed to.

Fully cleaned and polished externally. We make sure all consoles look as good as new by using an external plastic restorer and polish after a service.

The Delid Option

Should you delid a PS3? Sometimes. If the paste under the IHS is the problem, yes. But it’s a calculated risk. We have the equipment, the experience, and the steady hands to do it safely. But we also know when it’s not necessary.

This time it wasn’t. That’s a win.

Prevention

Don’t let your PS3 (or any console) get to this point. Keep it in a well-ventilated space. Don’t block the vents. If you notice the fan getting louder, that’s your early warning. Get it cleaned before it starts throttling.

PS3 Thermal Renewal Service — £55-75 (depending on whether delid is necessary)

12-month warranty included.
