A Zephyrus M16 owner discovered that the laptop's liquid metal thermal compound was corroding internal components, causing the system to overheat and shut down. This issue matters to buyers because it reveals a potential manufacturing defect that can destroy hardware and degrade performance. The owner had to disassemble the device to identify the corrosion on the heatsink and processor die.
Repasting with standard thermal paste restores performance
The root cause appears to be a chemical mixture used to contain the liquid metal. A Redditor named nicknickmeetnick stated that ASUS was mixing liquid metal with abrasive chemicals, leading to corrosion on both the heatsink and processor die crystal. This chemical reaction damaged the thermal interface between the cooling solution and the silicon.
The owner resolved the issue by repasting the laptop with G900 thermal paste. This fix resulted in a threefold increase in frames per second compared to the corroded state. The owner also recommended using PTM7950 thermal pads as a safer alternative to liquid metal for this model. These pads cost around $23.69 for an 80 x 80 x 0.25mm sheet on Amazon.
A 20-gram pack of UTX-Ultra thermal paste is listed for $25.99. We looked at thermal management issues in gaming laptops earlier while tracking ASUS hardware reports. The corrosion suggests that the chemical additive intended to prevent spillage may be damaging the hardware over time. Owners should monitor their devices for overheating signs and consider repasting if they experience sudden performance drops.
