Lenovo Fan System L 82H8 SUNON (5F10S13944) - CPU Cooling Fan for IdeaPad 3 15 Series

When your Lenovo IdeaPad 3 15 starts overheating during video calls or heavy multitasking, this CPU cooling fan restores reliable heat dissipation. It is a direct replacement for the original fan assembly in several IdeaPad 3 15 models, including 15ITL6, 15ALC6, 15ADA6, 15IGL6, 15IGL05, 15ITL05, 15ADA05, 15IML05, 15IIL05, and 15ARE05. The fan uses a 4-pin PWM connector for automatic speed control based on CPU temperature, keeping noise low during light tasks and ramping up under load.
