This brand new integrated dual CPU and GPU cooling fan matches original fan model ND85B24-18K01 and Lenovo OEM part DC28000E1D0, specially developed for Lenovo IdeaPad L330 and L340 budget gaming laptops, covering L340-15IRH, L340-17IRH, L330-15IRH, L330-17IC, L330-15ICH and L330-17ICH all variants.

Equipped with 8-wire PWM cable, it seamlessly communicates with laptop BIOS thermal management system to dynamically adjust rotation speed under light daily office tasks or intensive high-load gaming. Dual optimized curved turbine blades generate dual-channel concentrated airflow to rapidly evacuate heat from CPU and graphics chip simultaneously. It perfectly resolves common fan malfunctions: loud grinding noise, persistent high-temperature alerts, game frame drops and random power-off caused by aging or dust-blocked original cooling fans.

Adopting long-life silent fluid bearing and integrated anti-vibration cushion structure, vibration and running noise are greatly suppressed during marathon gaming, video editing and 3D graphic design work. Every cooling fan undergoes strict airflow, voltage and durability quality inspection before shipment. The fan housing outline, mounting screw positions and cable length are 100% consistent with factory original dual fan module, no wire cutting or chassis trimming required for easy self-repair or professional IT maintenance. It is a cost-effective cooling spare part to restore stable high-performance heat dissipation for Lenovo L series entry gaming notebooks.
