PlayStation 5 Overheating: Liquid Metal, Thermal Paste, and the Best Setup to Protect Your Console
The PlayStation 5 is designed with an advanced cooling system, including liquid metal, to manage heat more effectively than previous consoles. However, overheating and thermal related issues are still something we regularly see, especially as consoles age or are used heavily.
The challenge is that many people are unaware of how the cooling system actually works, or how factors like orientation, dust build up, and thermal materials affect long term reliability.
Below are some of the most important things to understand about liquid metal, thermal paste, and how to prolong the life of your PS5.
1. What Is Liquid Metal and Why the PS5 Uses It
Unlike traditional consoles that use standard thermal paste, the PS5 uses liquid metal between the processor and the heatsink.
Liquid metal is far more efficient at transferring heat away from the processor. This allows the console to run cooler and maintain performance under load.
However, it also requires precise application. If it shifts, dries out, or becomes uneven over time, cooling performance can drop significantly.
2. How Liquid Metal Can Cause Problems Over Time
While liquid metal is highly effective, it is not completely maintenance free.
Over time, the console’s position and heat cycles can cause the liquid metal to move slightly or spread unevenly. In some cases, this can lead to hotspots where heat is not being transferred correctly.
This is more likely in consoles that are used heavily, poorly ventilated, or positioned in ways that affect how the liquid metal sits on the processor.
3. Thermal Paste in the Cooling System
Although the processor uses liquid metal, other components within the PS5 still rely on thermal paste and thermal pads.
These materials help transfer heat from memory chips and power components to the heatsink. Over time, thermal paste can dry out or lose effectiveness, which contributes to increased temperatures.
If these materials degrade, the overall cooling performance of the console is reduced.
4. Signs of Cooling or Thermal Issues
There are several signs that may indicate your PS5 is struggling with heat management.
You may notice the fan becoming louder than usual, especially during gaming. The console may feel excessively hot, or performance may drop during longer sessions.
In more severe cases, the system may shut down unexpectedly to protect itself from overheating.
5. Best Orientation for the PS5 During Use
One of the most commonly asked questions is whether the PS5 should be used vertically or horizontally.
From a long term reliability perspective, horizontal positioning is generally considered the safer option.
Keeping the console horizontal reduces the risk of liquid metal shifting unevenly over time. It also helps maintain consistent contact between the processor and the cooling system.
While the console is designed to work in both orientations, horizontal placement can provide more stable thermal performance over the long term.
6. Importance of Ventilation and Environment
Even with advanced cooling, airflow is critical.
The PS5 should be placed in a well ventilated area with enough space around it to allow proper airflow. Enclosed spaces or placing the console near heat sources can cause temperatures to rise.
Dust build up is another common issue that restricts airflow and reduces cooling efficiency over time.
Why Proper Diagnosis Matters
Thermal issues are often overlooked or misdiagnosed. Many users assume the console is simply “running hot,” when in reality there may be underlying issues with cooling materials or airflow.
Opening the console without proper knowledge can make things worse, especially when dealing with liquid metal.
A proper diagnostic ensures the cooling system is assessed correctly before any maintenance or repair is carried out.
Repair or Maintenance What Are the Options
Depending on the condition of the console:
internal cleaning may improve airflow
thermal paste and pads may need to be refreshed
liquid metal may need to be inspected and correctly redistributed
Each of these requires careful handling to avoid causing further issues.
Next Steps
If your PlayStation 5 is showing signs of overheating or excessive fan noise, the safest approach is to have it properly assessed.
At Dead or Alive Technology, we carry out detailed diagnostics and internal inspections to ensure the cooling system is functioning correctly. This includes safe handling of liquid metal and thermal components.
Diagnostic services typically start from £40 and are deducted from the repair cost where appropriate.
