Sony has significantly enhanced the PS5 Pro PlayStation 5 Pro’s cooling system by refining its liquid metal thermal interface material (TIM) application. These improvements aim to address previous concerns about potential leakage and ensure more consistent thermal performance.
What’s New in the PS5 Pro Cooling System
1. Micro-Grooved Heatsink Design
The PS5 Pro introduces a heatsink with precisely engineered micro-grooves on the surfaces where liquid metal is applied. These grooves act as channels, effectively containing the liquid metal and preventing it from shifting or leaking, especially when the console is positioned vertically. This design not only stabilizes the liquid metal but also enhances heat transfer efficiency by increasing the contact surface area .
2. Enhanced Fan and Airflow
Complementing the improved heatsink, the PS5 Pro features a larger cooling fan with redesigned blades. This upgrade boosts airflow, ensuring that heat is dissipated more effectively, which contributes to the console’s overall thermal stability.
3. Addressing Previous Concerns
In earlier PS5 models, there were concerns about liquid metal potentially leaking, particularly when consoles were kept upright. While such incidents were rare, Sony’s redesign in the PS5 Pro directly addresses these issues by incorporating the grooved heatsink, thereby mitigating the risk of leakage and ensuring consistent cooling performance.
Maintenance and Application Guide
Over time, the liquid metal TIM can oxidize or become unevenly spread, especially if the console has been used extensively or stored vertically. Signs of degradation include overheating, performance throttling, or visible dry spots on the APU and heatsink. In such cases, reapplying the liquid metal may be necessary.
This guide provides instructions on safely disassembling your console, cleaning old liquid metal, and applying a fresh layer to ensure optimal thermal performance.
Why Sony Uses Liquid Metal
-
Superior Thermal Conductivity:
Liquid metal has much higher thermal conductivity than standard thermal paste, allowing heat to transfer more effectively from the APU to the heatsink. -
Improved Performance & Longevity:
-
Better cooling means the PS5 Pro can maintain higher clock speeds without overheating, leading to more stable performance and less wear on components over time. -
Quieter Operation:
Because the system stays cooler, the fans don’t need to run at high speed, which reduces noise.
Why It’s a Big Deal
-
Rare in Consumer Electronics:
Liquid metal is usually reserved for high-end PCs or enthusiast overclocking setups. Its use in a mass-market console like the PS5 Pro is unusual and shows Sony’s commitment to maximizing cooling and performance. -
Potential Risks:
Liquid metal is electrically conductive and corrosive to certain materials (like aluminum). Improper application can cause short circuits or long-term damage. That’s why Sony engineered a grooved heatsink and containment system in the PS5 Pro to safely manage it.

For Gamers
Cooling isn’t just a technical detail—it’s a critical factor that directly affects your gaming experience. Here’s why:
1. Stable Performance During Gameplay
-
High temperatures can cause thermal throttling, where the console automatically reduces performance to avoid overheating.
-
Good cooling ensures the GPU and CPU run at full power, delivering smoother frame rates and quicker load times.
2. Quieter Gaming Environment
-
An efficient cooling system means the fans don’t have to work as hard, which leads to less noise.
-
This makes a big difference during immersive, cinematic games where fan noise can break immersion.
3. Protects Against Hardware Damage
-
Overheating can degrade internal components over time, increasing the risk of failure.
-
Consistent cooling keeps temperatures in safe ranges, extending your console’s lifespan.
4. Reliable Long-Term Use
