Heatsink Lenovo for IdeaPad 5, original replacement (MPN 5H41B39806)

Replacement heatsink compatible with Lenovo IdeaPad 5 laptops. This original-design heatsink is intended to remove heat from the CPU and GPU area, helping to maintain stable operating temperatures and reduce the risk of thermal throttling. It is a direct-replacement component for repairs or refurbishments aimed at restoring the laptop's cooling performance and supporting prolonged device lifespan.

Advantages

The heatsink is built to match Lenovo's component specifications and fit within the IdeaPad 5 chassis geometry, providing efficient heat transfer and reliable contact with processor surfaces. Using an original-design part reduces the chance of installation fitment issues and helps maintain the laptop's designed thermal behaviour. Its metal construction and heat pipe design support consistent dissipation under typical laptop workloads.

Suitable for

• Repairing an IdeaPad 5 with degraded or damaged cooling components
• Replacing a faulty or noisy cooling system to restore thermal performance
• Refurbishment projects to return a used laptop to stable operating temperatures

Key specifications

• Compatibility: Lenovo IdeaPad 5 series laptops
• Function: heat dissipation for CPU and GPU components
• Material: metal heatsink with integrated heat pipe (original-design)
• Form factor: low-profile laptop heatsink sized for IdeaPad 5 internal layout

How to use

Replace the original heatsink by disassembling the laptop according to the manufacturer's service instructions, taking appropriate electrostatic discharge (ESD) precautions. Remove the old heatsink and clean thermal interface surfaces on the processor and heatsink contact points. Apply a thin, even layer of compatible thermal compound before positioning and fastening the replacement heatsink to ensure proper contact and heat transfer. Reassemble the laptop and verify cooling operation by monitoring temperature and fan behaviour during normal use.

Recommendations

Use this original-design heatsink only with the compatible IdeaPad 5 models. When installing, follow Lenovo service guides or seek qualified technician assistance to avoid damage. Replace thermal compound and check mounting screws for correct torque to ensure optimal thermal conductivity and long-term reliability.
