How to Get Thermal Paste off CPU: A Step-by-Step Guide

Thermal paste is a crucial component that helps in maintaining the temperature of your CPU. However, there are times when you need to remove old thermal paste in order to apply a fresh layer or switch to a different cooling solution. In this article, we will guide you through the process of getting thermal paste off your CPU.

Step 1: Power off your computer and disconnect all cables. Ensure that you are working in a clean and well-lit area.

Step 2: Gently remove the CPU cooler from your motherboard, ensuring that you don’t pull it off too forcefully and damage the CPU or motherboard.

Step 3: Using a lint-free cloth or coffee filter, wipe away as much of the thermal paste as possible. Be gentle and avoid applying excessive pressure.

Step 4: Apply a small amount of isopropyl alcohol (at least 90%) to another lint-free cloth or coffee filter. Dab the cloth with alcohol and gently wipe the remaining thermal paste off the CPU and cooler.

Step 5: Repeat the process until all traces of thermal paste are removed. Ensure that both the CPU and cooler are completely dry before reapplying thermal paste.
