How to apply liquid metal thermal paste?

Before applying the liquid metal thermal paste, clean the CPU first making sure there is no dust or particles. If it’s a new processor, you can skip this part. It’s a good idea to use a cotton swab, paper towel or alcohol in cleaning.

Moreover, if you have installed a CPU cooler, you also need to remove it first. You can refer to your computer manual for the proper instructions. You could also check the following video to get a glimpse of how to remove a CPU cooler:

Steps to Apply Thermal Paste on CPU

  1. After removing the CPU cooler, apply alcohol on the paper towel and use it to remove the old thermal paste from the surface of the cooler. Keep it shiny and clean then set it aside.
  2. Do the same cleaning on the top of your CPU using a paper towel dabbed with alcohol. Additionally, clean the sides of the CPU using a dry cotton swab. The CPU should look clean without any residue or streaks.
  3. At this point, take out your liquid thermal paste in preparation for the application. There are several ways to apply the thermal paste, the most common of which is the dot or P method. The most important thing is to never over-apply as it can spill over to the side of the CPU which may cause issues later on, which can also be a mess to remove when it’s time to replace the thermal paste.
  4. Carefully apply the thermal paste on top of the CPU, and once that’s done you may already return the cooler. Keep the connection nice and tight to ensure having even pressure between the CPU and the cooler.

You could follow the same steps for applying liquid metal. The only difference is that for liquid metal, it’s a good idea to evenly cover the entire CPU surface. Here’s a video for more information on how to do it:

Q & A

What’s the best material to use – liquid metal or thermal paste?

Both liquid metal and thermal paste are used for heat management in CPU, GPU and heat sink. Liquid metal generally has up to 73 W/(mK) thermal conductivity while thermal paste has lower thermal conductivity. However, all liquids are typically electroconductive and that can sometimes lead to other issues down the line.

How often do you need to change liquid metal or thermal paste?

Not that often, but generally it depends on the current temperature management on your computer. You can check this video to give you an idea.

How does liquid metal thermal paste work?

Liquid metal thermal paste are designed to reduce microscopic air gaps between the surface of the cooler and the CPU’s integrated heat spreader. Liquid metal thermal paste can be electrically conductive or non-conductive. The liquid metal compounds need a greater concentration and attention when applied.

What is the best method to apply thermal paste?

One of the most common methods used is often referred to as the “line method.” This is exactly as it sounds. Apply a thin line of thermal paste directly down the center of the IHS (Integrated Heat Spreader) and then allow the pressure of the CPU cooler to spread the paste as you secure it.

How do you use liquid metal filler?

Apply LIQUID METAL FILLER straight from the tube. If desired, use a wet putty knife or spatula to smooth out the repair. LIQUID METAL FILLER will dry in 3 to 4 hours. For filling deep holes, apply LIQUID METAL FILLER.

Do I need to replace liquid metal?

No, it can’t be replaced, it’s a one-time thing and yes the temps do drop but I’d advise against it and leave the stock cooling solution as is, just replace the TIM with something high quality.

How long does metal filler take to dry?

Allow the filler to dry 20 minutes at 77 degrees F (25 degrees C). In cooler climates, filler may take longer to dry, in warmer climates filler will set up quicker.

How hot is liquid metal?

The only stable liquid elemental metal at room temperature is mercury (Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F).


Liquid metal and thermal paste are two different materials commonly used to manage the heat in your computer. They are easy to apply and the only requirement is for you to thoroughly clean the CPU surface before doing so.
