Lenovo Jaguar-1/Panther-1 FRU

The Lenovo FRU thermal module with part number 5H40W36671 is a genuine replacement cooling component designed specifically for Lenovo notebook computers. This thermal management system consists of a heat pipe assembly, cooling fins, and an integrated fan designed to efficiently dissipate heat from critical notebook components including the processor and graphics chip. The module features precision-engineered copper heat pipes that provide optimal thermal conductivity, ensuring stable performance during extended computing sessions.

With dimensions typically around 15 cm in length and 8 cm in width, this compact cooling solution fits seamlessly into compatible Lenovo notebook chassis. The integrated brushless DC fan operates at variable speeds between 2000 and 5000 RPM, providing adaptive cooling based on system thermal demands while maintaining acoustic levels below 35 dB during normal operation.

Constructed with durable materials including anodized aluminum fins and copper heat pipes, this thermal module offers reliable heat dissipation performance. The module maintains processor temperatures within optimal operating ranges of 40-85°C depending on workload intensity.

Installation requires technical expertise and proper thermal compound application to ensure optimal heat transfer between components. This replacement part is compatible with specific Lenovo notebook models that originally used the 5H40W36671 thermal module configuration. The design incorporates multiple heat transfer surfaces and optimized airflow channels to maximize cooling efficiency within the constrained space of modern notebook computers. Proper maintenance of the thermal system helps prevent performance throttling and extends the operational lifespan of notebook components by maintaining appropriate operating temperatures.
