Tools You’ll Need
- Thermal paste
- Isopropyl alcohol (90% or higher)
- Lint-free cloth or coffee filter
- Plastic card or thermal paste spreader
- Screwdrivers
- Compressed air (optional)
Step-by-Step Guide
1. Power Down and Unplug
Ensure your PC is completely powered down and unplugged from the wall outlet. Disconnect all peripherals and move your PC to a clean, static-free workspace.
2. Open the PC Case
Remove the side panel of your PC case using a screwdriver. This will provide access to the CPU cooler.
3. Remove the CPU Cooler
Carefully disconnect the CPU cooler’s power cable from the motherboard. Unscrew or unclip the cooler, depending on its mounting mechanism, and gently lift it off the CPU.
4. Clean the Old Thermal Paste
Use isopropyl alcohol and a lint-free cloth to clean the old thermal paste from the CPU and the cooler's base. Ensure both surfaces are completely clean and free of residue.
5. Apply New Thermal Paste
Apply a small, pea-sized amount of thermal paste to the center of the CPU. Use a plastic card or thermal paste spreader to evenly distribute it across the surface, if needed.
6. Reattach the CPU Cooler
Place the CPU cooler back onto the CPU, ensuring it aligns with the mounting holes. Secure it in place by tightening screws or clipping it down. Reconnect the power cable to the motherboard.
7. Close the PC Case and Power Up
Reattach the side panel of your PC case and reconnect all peripherals. Plug in your PC and power it up. Check the temperatures using monitoring software to ensure the thermal paste is functioning correctly.
