When should the thermal paste be reapplied in HP devices?

Reapplying thermal paste is crucial for maintaining optimal thermal conductivity between the CPU and the heatsink. It should be done when servicing for overheating issues or after replacing the CPU because these situations can disrupt the effective heat transfer necessary for proper functioning.

Over time, thermal paste can degrade, dry out, or become less effective, particularly if the system has been experiencing overheating. Applying fresh thermal paste in such cases ensures that the CPU can maintain appropriate operating temperatures, thereby prolonging the lifespan of the components and ensuring system stability.

When replacing a CPU, removing the old thermal paste is necessary to ensure that the new CPU has a clean surface and can be correctly seated with new thermal paste, allowing efficient heat dissipation. In contrast, options about reapplying thermal paste after every system boot or every six months lack the context of actual need, as regular booting does not affect paste condition, and six months may not be relevant if the device is functioning properly. Additionally, the warranty period does not dictate maintenance tasks like thermal paste application; it is concerned primarily with coverage of defects rather than ongoing maintenance.
