This component may not be suitable for laptop models outside of the specific Toshiba configurations for which it was designed. Attempting to install this part in an incompatible device may result in poor thermal contact or physical damage to the motherboard.

Key specifications

• Genuine thermal management component
• Designed for specific Toshiba hardware configurations
• Optimized for efficient heat dissipation
• Durable metal construction

How to use

Installation should be performed by a qualified technician or an experienced user familiar with laptop disassembly. Begin by powering off the device and disconnecting the power supply and battery. Carefully remove the bottom casing to access the cooling system. Unscrew the existing heatsink assembly, ensuring that any thermal paste residue is cleaned from the processor surface using isopropyl alcohol. Apply a thin, even layer of new thermal compound to the processor die before positioning the new heatsink. Secure the assembly using the original screws, ensuring even pressure across the mounting points, and reassemble the laptop.

What to consider before purchase

• Verify compatibility with your specific laptop model and motherboard version
• Ensure you have the necessary tools for laptop disassembly
• Check if your current thermal paste needs replacement during the installation
• Confirm that the cooling fan is also functioning correctly

Usage recommendations

Regularly clean the air vents of your laptop to prevent dust accumulation, which can impede the performance of the heatsink assembly and lead to increased operating temperatures.
