What is thermal paste?
How to Replace Laptop Thermal Paste? Thermal paste, also known as thermal compound or grease, is between the CPU or GPU and the heatsink; It fills microscopic air pockets to help evenly transfer heat from the chip to the cooler.
Types of thermal paste include:
- Ceramic-based: Non-conductive and safe, ideal for beginners.
- Metal-based: High performance but a bit conductive.
- Carbon-based: It strikes a balance for safety and results.
- Liquid metal: Best for pros-only applications, highly conductive, but very dangerous on laptops. How to Replace Laptop Thermal Paste?
Why Replace Thermal Paste?
- Smarter Cooling: New paste spreads the heat well, hence the system keeps cool during tough tasks.
- Stronger Performance: Lower temperatures allow parts to run fast without slowing down.
- Extended Life: Less heat wear helps hardware last for more years.
- Less Noise: The fans spin slower; hence, it is generally quieter. How to Replace Laptop Thermal Paste?

Step 2 – Locate the CPU and GPU
With the cover removed, locate the cooling system. There are copper pipes attached to a fan and a plate over the CPU and GPU.
Step 3 – Remove the Heatsink
Loosen the heatsink screws in a crisscross manner. Lift it slowly; don’t yank. If stuck, give a gentle twist to loosen the old paste. How to Replace Laptop Thermal Paste?
Step 4 – Wipe Away Old Paste
Wet a cloth or swab with alcohol, and wipe the paste off of the chip and heatsink bottom until both shine clean.
Step 5 – Apply Fresh Paste
Place a small pea dot in the chip’s center. When you put the heatsink back it will spread it. Avoid spreading with fingers since this will create air pockets which degrade cooling performance.
Step 6 – Put it back together
Place the heatsink and start tightening the screws in the same order. Connect the cables, put on the back cover and finally insert the battery. How to Replace Laptop Thermal Paste?
