Lenovo 01hw697 Laptop Thermal Fan Uma ET481

Product Description

The LENOVO 01hw697 is a thermal fan assembly designed for use in Lenovo laptop systems as an OEM replacement cooling component. Identified by the ET481 board reference, this unit handles active CPU cooling by moving airflow across the heatsink to dissipate heat generated during processor operation. The UMA designation indicates compatibility with unified memory architecture graphics configurations, meaning no discrete GPU heatsink path is present. Licensed HVAC and electronics technicians as well as experienced laptop repair technicians typically handle this type of cooling system replacement.

This thermal fan assembly is suited for Lenovo laptop platforms that use integrated graphics configurations. It is a direct OEM-style replacement intended for technicians servicing systems where the original fan has failed, become noisy, or is no longer maintaining safe operating temperatures under load. The ET481 part reference assists in verifying correct fitment during the parts lookup process.

Key Features

• OEM replacement thermal fan assembly for Lenovo laptop systems
• UMA configuration — compatible with integrated graphics platforms only
• ET481 board reference for fitment verification during procurement
• Delta fan motor construction per the original equipment specification
• Direct drop-in replacement to restore active CPU cooling performance

Compatibility

Designed as an OEM-style replacement thermal fan for Lenovo laptop systems using a UMA integrated graphics configuration. Verify fitment using the ET481 board reference and the MPN 01hw697 against the specific system service manual before ordering.

Installation Notes

Installation should be performed by a qualified laptop repair technician. Power down the system completely and disconnect the battery before removing the existing fan assembly. Handle the fan connector carefully to avoid damage to the motherboard header. Follow the system-specific service manual for disassembly sequence and screw torque guidance, as procedures vary by platform.
