Intel has reportedly denied an RMA request for a Core i9-14900K CPU due to the usage of liquid metal thermal paste. The processor, part of the 13th Generation Raptor Lake and 14th Generation Raptor Lake Refresh CPUs, experienced instability issues.
The issue arises from liquid metal’s corrosive nature, which can remove chip markings, making it difficult for Intel to verify warranty claims. Liquid metal offers excellent thermal conductivity but is electrically conductive, posing a risk if not applied correctly.
Intel has warned that using liquid metal can void the processor’s warranty due to its corrosive properties. The latest incident highlights the risks associated with using liquid metal as a thermal paste, especially when used on integrated heat spreaders (IHS).
To minimize risks, enthusiasts should consider alternative cooling solutions or follow proper application procedures when using liquid metal. However, for most consumers, the benefits of liquid metal do not outweigh the potential drawbacks.
It’s essential to note that liquid metal can be cleaned and restored with chemicals, but gentle handling is required to avoid removing the chip markings. The processor’s warranty should remain a top priority for those considering alternative cooling methods.
