5H40S20449 CPU and GPU Cooling Fan Assembly and Heatsink Compatible with Lenovo Laptops (4-Pins, 5V)

Description

A laptop relies on a cooling fan and heatsink to pull heat away from the processor and graphics chip. When the fan wears out, the machine runs hot, makes a loud clicking noise, and can shut down mid-task. Installing this Lenovo 5H40S20449 cooling fan assembly replaces the failing unit with a 4-pin assembly that fits the original mount.

The new fan spins quietly and keeps temperatures stable, so the laptop handles work and games without overheating.

Key Benefits:

• Connects via a 4-pin wire to the board for reliable power and speed control.
• Fixes loud clicking and grinding noises from a worn fan motor.
• Resolves overheating that causes sudden shutdowns during heavy tasks.
• Restores quiet, cool operation so the laptop runs all day smoothly.
• Mounts directly into the original heatsink position for a simple swap.
