Since its launch, the PS5 Slim has adopted a liquid metal cooling system, supposed to advantageously replace classic thermal paste. But this innovation, although effective, can prove delicate in the long term. When the console is used in an upright position, the liquid metal may distribute unevenly or even oxidize, causing the fan to overheat, slow down, or malfunction.
This phenomenon is starting to worry some users, especially as Christmas approaches, a period when consoles are running at full speed. Fortunately, iFixit offers a simple solution to implement at home.
Signs that should alert you
Before disassembling your PS5 Slim, a few symptoms may indicate that the liquid metal is no longer fulfilling its role correctly:
- The console becomes abnormally hot even when idle
- Performance suddenly drops (frequency slowed)
- The fan is running at full speed for no apparent reason
- Unexpected shutdowns or system errors occur frequently
If you notice these problems, cleaning and reapplying the liquid metal may be enough to give your machine a new lease of life.
The step-by-step guide recommended by iFixit
The iFixit site offers a complete procedure, detailed in simple steps. Here is a clear summary:
- Remove the cover, disk drive, and expansion port cover with a screwdriver
- Disconnect the fan cables, then remove the fan itself
- Remove the motherboard cover screws to access the internal components
- Disconnect the antenna cables, interconnect cable, and remove the heat sink
It is then time to move on to cleaning the liquid metal.
Cleaning and Reapplying Liquid Metal: How to Do It
iFixit recommends wearing gloves to avoid direct contact. Use a disposable syringe to remove the old liquid metal on the heat sink. Using a cotton swab dipped in concentrated isopropyl alcohol, carefully clean the heatsink and APU processor.
Next, apply the new liquid metal. “the equivalent of a match head” is enough according to experts. Spread the substance with a clean cotton swab or applicator provided in specialized kits.
All you have to do is reassemble each part following the reverse order of disassembly. Your PS5 Slim is now ready to go for several years.
