2. Disconnect the AC adapter and remove the battery (if removable).
3. Place the laptop on a clean, flat, and static-free surface.
4. Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage.

Step-by-Step Installation

1. Access the Motherboard: Carefully open your laptop's bottom cover to access the internal components, including the CPU cooling fan. Refer to your laptop's specific service manual for precise instructions on removing the back panel.
2. Locate the Old Fan: Identify the existing CPU cooling fan. It will typically be connected to the heatsink and motherboard.

3. Disconnect the Fan Cable: Gently disconnect the 4-pin power cable of the old fan from its connector on the motherboard. Use a plastic pry tool if necessary to avoid damaging the connector.
4. Remove Mounting Screws: Unscrew the two M2x5 screws (or similar) that secure the fan to the laptop chassis or heatsink. Keep these screws safe as they will be reused.

5. Remove the Old Fan: Carefully lift and remove the old CPU cooling fan from its position.
6. Clean CPU/GPU (Optional but Recommended): If you are also replacing the heatsink or reapplying thermal paste to the CPU/GPU, gently clean off any old thermal paste from the CPU/GPU die and the heatsink contact area using isopropyl alcohol and a lint-free cloth.
7. Apply Thermal Grease: Apply a small amount of the included thermal grease to the center of the CPU die. This helps ensure efficient heat transfer between the CPU and the heatsink.
8. Position the New Fan: Place the new Deal4GO CPU cooling fan into the designated slot, ensuring it aligns correctly with the screw holes and the heatsink.

10. Connect the Fan Cable: Carefully connect the 4-pin power cable of the new fan to the corresponding connector on the motherboard. Ensure it is seated firmly.
11. Reassemble Laptop: Reattach the laptop's bottom cover, ensuring all clips and screws are properly secured. Reconnect the battery and AC adapter.
12. Test Functionality: Power on your laptop and verify that the fan spins correctly and the system boots without errors. Monitor CPU temperatures to ensure proper cooling.

7. Operating the CPU Cooling Fan

The Deal4GO CPU Cooling Fan operates automatically. It is controlled by your laptop's system BIOS/UEFI and operating system, which regulate its speed based on the CPU temperature and system load. No manual intervention is typically required for its operation.

8. Maintenance

To ensure optimal performance and longevity of your CPU cooling fan:

• Regular Cleaning: Periodically (e.g., every 6-12 months, depending on usage environment) clean dust from the fan blades and heatsink fins. Use compressed air or a soft brush. Ensure the laptop is powered off and disconnected from power before cleaning.
• Avoid Obstructions: Ensure the laptop's air vents are not blocked by objects or surfaces (e.g., blankets, soft furniture) during operation.
• Monitor Temperatures: Use system monitoring software to occasionally check CPU temperatures. Consistently high temperatures may indicate a need for more thorough cleaning or reapplication of thermal paste.
