5H40H91134 - Lenovo Laptop CPU Fan & Heatsink - Genuine

This Lenovo Laptop CPU Fan & Heatsink (5H40H91134) is a genuine part designed specifically for Lenovo laptops. It includes both the CPU fan and the heatsink, ensuring your device remains cool during operation. The CPU fan circulates air to dissipate heat, while the heatsink absorbs and disperses heat away from the CPU, working together to prevent overheating. Also known as "HS Heat Sinks," this component is crucial for maintaining optimal performance and preventing thermal damage.

If your laptop is experiencing overheating, unexpected shutdowns, or reduced performance, it might be time to replace the CPU fan and heatsink. These symptoms can indicate that the cooling system is no longer functioning efficiently.

Before purchasing, verify your device's model number to ensure compatibility with this essential cooling part.
