ND85B24-18K01 DC28000E1D0 DTA3 Dual CPU GPU Cooling Fan Replacement for Lenovo IdeaPad L340-15IRH L340-17IRH C340-15IWL Flex 15IWL Gaming Laptop Cooler

This brand new dual CPU & GPU cooling blower fan matches original fan model ND85B24-18K01 and Lenovo OEM part DC28000E1D0 DTA3, custom-made for Lenovo IdeaPad L340-15IRH, L340-17IRH, C340-15IWL and Flex-15IWL performance gaming laptops.

Equipped with a 4-wire PWM plug, it seamlessly communicates with the laptops built-in thermal management system to dynamically adjust rotation speed under light office tasks or heavy gaming loads. Dual optimized curved turbine blades generate concentrated dual-channel airflow to rapidly dissipate heat from CPU and graphics chip simultaneously, perfectly solving common failures including loud rattling fan noise, persistent high-temperature alerts, game frame drops and unexpected auto shutdown caused by dust-clogged or worn original cooling fans.

Adopting premium silent fluid bearing and integrated anti-vibration foam frame, vibration and whining noise are greatly suppressed during marathon gaming, video editing and 3D design work. Every fan undergoes strict airflow, voltage and durability quality inspection before shipment. The fan housing dimensions, screw hole positions and cable length are 100% consistent with the original factory dual fan assembly, no wire cutting or chassis trimming required for easy self-repair or professional maintenance. It is a cost-effective cooling repair spare part to restore stable high-performance heat dissipation for Lenovo L340 series budget gaming laptops.
