PS5 Pro Liquid Metal Reapplication: Fixing Overheating at GET Repairs Glasgow

Since the launch of the PlayStation 5 Pro, we’ve seen a significant uptick in customers visiting our Glasgow workshop reporting the same set of symptoms: excessive fan noise, sudden shutdowns during high-fidelity games, and the dreaded 'Your PS5 is too hot' warning.

At GET Repairs, we deal with these issues daily. While many users assume it is a simple dust buildup, the PS5 Pro’s cooling architecture relies on a specialized liquid metal thermal interface material (TIM). Unlike traditional thermal paste found in older consoles, liquid metal is a gallium-based alloy that remains fluid. When it works, it is incredibly efficient; when it fails, it can lead to catastrophic hardware failure.

The Problem: Dry Spots and Oxidation

The PS5 Pro uses a nickel-plated copper heatsink pressed against the Accelerated Processing Unit (APU). Because the console is often stored vertically, the liquid metal can, over time, migrate due to gravity, surface tension changes, or thermal cycling. This results in 'dry spots' where the APU die is no longer in contact with the coolant.

Furthermore, even though the system is sealed with a foam barrier, we frequently observe minor oxidation on the surface of the heatsink. This creates a crusty residue that acts as an insulator rather than a conductor. By the time you hear your fans hitting maximum RPMs, the internal temperatures are likely exceeding 90°C, causing the system to throttle performance to protect the silicon.

Why DIY is Risky

We generally discourage users from attempting a liquid metal reapplication at home for three reasons:

1. Conductivity: Liquid metal is highly electrically conductive. A single microscopic droplet spilled onto the motherboard will cause an immediate short circuit, often killing the console instantly.
2. Oxidation Removal: Simply adding more liquid metal doesn't work. The existing oxidation 'stain' on the heatsink must be chemically and mechanically polished off using high-grit abrasives or specific cleaning agents to ensure a mirror finish.
3. The Seal: The foam gasket surrounding the APU must be perfectly intact. If it is pinched or displaced during reassembly, the liquid metal will leak out under pressure.

Our Professional Repair Process

When you bring a PS5 Pro into our Glasgow shop for an overheating fix, we follow a strict technical protocol:

1. Full Disassembly: We strip the console down to the APU level, removing the fan, power supply, and secondary shielding.
2. Cleaning and Polishing: We remove the old, degraded liquid metal. We then polish the nickel-plated surface of the heatsink to remove oxidation buildup.
3. Application: We apply a fresh, measured dose of high-grade thermal interface material. We ensure it is 'wetted' into both the APU surface and the heatsink to prevent future dry spots.
4. Deep Clean: While the unit is open, we clear the internal heatsink fins and the fan assembly using compressed air and anti-static brushes.
5. Stress Testing: We run the console through a 30-minute stress test using a demanding title like Horizon Forbidden West or Cyberpunk 2077 to monitor stable thermal output.

Signs Your PS5 Pro Needs Service

If you notice the following, it is time to have the thermal interface checked:

• The fan ramps up to a loud 'vacuum cleaner' noise within minutes of starting a game.
• The console shuts down without warning (no light, no beep) during intense scenes.
• You see graphical glitches or 'artifacts' on the screen.
• The back of the console feels unusually cool while the fan is spinning fast (this indicates heat is not being transferred from the chip to the heatsink).

Expected Costs in the UK

Repairing the thermal interface is significantly cheaper than replacing a burnt-out APU or a mainboard. In the UK market, and specifically here in Glasgow, you should expect to pay within these ranges for professional service:

• Standard Thermal Service (Clean + Liquid Metal): £60 – £85
• Full Internal Restoration (Including fan replacement if bearings have failed): £90 – £120

Avoid 'budget' shops offering this for £20; high-quality liquid metal is expensive, and the labour required to safely clean a PS5 Pro takes roughly 60 to 90 minutes of precision work.

Final Thoughts

The PS5 Pro is a powerful machine, but like any high-performance vehicle, it requires specific maintenance. If your console is struggling with heat, don't wait for it to stop turning on entirely.
