Lenovo ventoinha System L 82H8 AVC (5F10S13942)

The Lenovo Fan System L 82H8 AVC (5F10S13942) is a direct replacement cooling assembly engineered for IdeaPad 3 15-inch laptops. Unlike generic coolers, this unit combines a PWM-controlled AVC fan with a copper heat pipe and aluminum fin stack, matching the original thermal design for reliable heat dissipation.

Highlights

• Designed for Lenovo IdeaPad 3 15ITL6, 15ALC6, 15ADA6, 15IGL6, 15IML05, 15ITL05, 15ADA05, 15ARE05, 15IGL05 and other 15-inch IdeaPad 3 series models
• FRU part number 5F10S13942; alternate part numbers DFS5M32506311F, BAZA0508R5H P001
• 4-pin PWM connector for automatic fan speed control
• Hydraulic bearing for quiet operation and long service life
• Copper heat pipe with aluminum fins for efficient heat transfer

In daily use

This cooling fan system restores proper thermal performance to compatible IdeaPad 3 laptops. The PWM fan adjusts speed based on CPU temperature, keeping noise low during light tasks and increasing airflow under load. The single heat pipe draws heat away from the processor to the fin stack, where the fan exhausts it through the chassis vents.
