Cooling thermal module Lenovo IRONHIDE-3.0 (MPN 5H41B77169) — laptop thermal assembly

Lenovo IRONHIDE-3.0 laptop thermal module is a compact cooling assembly engineered to transfer heat away from central processing and graphics units to the heatsink and fan. Designed as a direct-replacement part for compatible Lenovo notebooks, this thermal module restores or improves thermal conduction between the CPU/GPU and the cooling system, helping maintain stable operating temperatures during sustained workloads and reducing thermal throttling risks.

Advantages

The module provides efficient heat conduction through pre-formed heatpipes and a contact plate designed for laptop internal layouts, enabling uniform heat distribution to the heatsink. It is manufactured to meet OEM mechanical tolerances for straightforward fitment in supported models, which simplifies repair or upgrade tasks. Using a dedicated replacement thermal assembly helps restore factory-level cooling performance and can extend component longevity by maintaining acceptable operating temperatures.

Suitable for

• Repairing cooling system failures in compatible Lenovo notebooks
• Replacing worn or damaged thermal assemblies after intensive use
• Maintaining stable CPU/GPU performance under prolonged load
• Technical service and laptop refurbishment projects

Key specifications

• Type: laptop cooling/thermal module with heatpipes and contact plate
• Function: conducts heat from CPU and GPU to heatsink and fan
• Form factor: compact, designed for specific Lenovo internal layout and mounting points
• Materials: metal heatpipes and metal contact surfaces for thermal conduction
• Compatibility: intended as a replacement thermal assembly for compatible Lenovo notebook models

How to use

Power off the laptop, disconnect the battery and remove external power before beginning any work. Disassemble the laptop housing according to the manufacturer's service guide to access the existing thermal assembly. Carefully detach the original module from its mounting points and clean the CPU/GPU contact surfaces with isopropyl alcohol to remove old thermal compound. Install the replacement module ensuring alignment with screw holes and contact surfaces, apply new thermal paste where required, and reassemble the laptop. Verify fan operation and monitor temperatures after reassembly.

Usage recommendations

Use the replacement thermal module only in models for which it is specified and follow official disassembly instructions. Replace thermal paste during installation and avoid overtightening mounting screws to preserve contact integrity. If unsure about compatibility or installation, seek assistance from authorized service personnel.
