This Lenovo Laptop Heatsink (5H40S72926) is a genuine part designed specifically for Lenovo laptops. Compatible with various models, this component, also known as a "heat sink" (when separate from the fan), plays a critical role in your laptop's cooling system. By dissipating heat generated by the CPU or GPU, it helps prevent overheating, ensuring your laptop runs efficiently and maintains its performance over time.
