Thermal paste is a high-conductivity substance that’s applied between the GPU die and heatsink. It fills in microscopic gaps and imperfections between the two surfaces, enabling efficient heat transfer and preventing overheating and performance throttling.

The process of applying new thermal paste is fairly straightforward, though it does require some disassembly and cleanup. You’ll need a couple of essential tools, including isopropyl alcohol and a lint-free cloth.

It’s also a good idea to wear disposable gloves to protect your hands from oils and dirt, which could interfere with the thermal paste. You can find a variety of applicators available, from plastic syringes to small ziplock bags with cut corners. The key is to apply a thin and even layer.

Once you have your tools, you’ll want to turn off the computer and disconnect any power sources. You may also wish to unplug the fan cables if you have extra room (and remember to plug them back in later). Then, remove the GPU and place it on a clean, static-free surface.

If necessary, use a screwdriver to detach the heatsink from the GPU. Next, gently wipe away any dirt or debris from the heatsink using a lint-free cloth. Lastly, use compressed air to blow any loose particles from the heatsink’s contact area with the GPU die. GPU thermal paste
