Replacement Fan for Lenovo Z50-70 and Z40-70

This replacement cooling fan is designed specifically for Lenovo Z50-70 and Z40-70 laptops. It serves as a direct substitute for a worn or faulty original cooler. Each unit is tested individually before dispatch to confirm it operates correctly. The package includes one fan ready for installation.

Upgrading from a failing original cooler

When the original fan becomes noisy, spins irregularly or stops completely, this part restores proper airflow. The jump is worth it if thermal throttling or unexpected shutdowns occur due to insufficient cooling. Buyers should verify the part visually against their current fan before purchase to ensure the correct match. Compatibility cannot be guaranteed for other laptop models.

Cooling capacity for supported Lenovo models

The fan provides the airflow intended for the Z50-70 and Z40-70 thermal design. It handles typical workloads that the original cooling system was built to manage. It runs out of capacity if the heatsink fins are clogged with dust or if thermal paste has degraded beyond effectiveness. The part does not increase the cooling potential beyond the laptop's original specification.
