General Information About Thermal Pastes

How does thermal paste work?

Thermal paste is a type of Thermal Interface Material (TIM) commonly used to fill microscopic gaps between two surfaces. In a PC, it is primarily applied between the CPU and the CPU cooler. The carrier material, such as silicone oil, contains microscopic particles like aluminum oxide or zinc oxide, which help transfer heat from the CPU to the cooler.

What is conventional thermal paste?

We classify our X-8 and X-10 products as "conventional" thermal pastes. These products consist of a carrier material (also called a matrix material), such as silicone oil, combined with integrated nanoparticles for heat conduction. These nanoparticles are typically made from electrically non-conductive oxides like aluminum oxide.

What is liquid metal?

Liquid metal is usually a gallium-based thermal interface material (TIM) that often includes other metals like indium. This metal mixture remains liquid at room temperature. Unlike thermal paste, liquid metal does not contain particles like aluminum oxide and can be applied in an extremely thin layer between the CPU and the cooler, offering excellent heat transfer.

Can I use Polartherm thermal pastes for overclocking?

Polartherm thermal pastes are suitable for standard overclocking applications.

Application, Removal, and Storage

How do I apply thermal paste?

Thermal paste can be applied directly or using the included spatulas or applicators. Detailed instructions can be found on the product pages.

Does the application pattern matter?

The pattern—such as a dot in the center, a cross, or a line—depends on the size of the heat spreader. For larger CPU heat spreaders, it is best to spread the paste evenly using a spatula.

How do I remove thermal paste?

To remove thermal paste, start by cleaning roughly with a paper towel. Then, use an isopropyl alcohol-based cleaner to wipe off any residue.

How long can I use thermal paste before replacing it?

Thermal paste should be replaced when temperatures start to deteriorate.

How do I use the applicator and spatula?

Spatula Method: Use the included spatula to spread the paste across the CPU surface. The cooler will compress the paste, ensuring complete coverage even in the smallest areas.

Applicator Method: Use the included applicator to apply a thin, even layer of paste directly onto the CPU's heat spreader. The cooler's mounting pressure will fill any remaining gaps.

How should I store opened thermal paste?

It is recommended to store the syringe in its original packaging, away from direct sunlight (UV radiation).

What is the shelf life of Polartherm thermal paste after opening?

With proper storage and packaging, the thermal paste can be used for at least three years, often much longer.

Troubleshooting

I lost the applicator/spatula. What should I do?

For best results, we recommend spreading the paste across the chip's entire surface. If this is not possible, you can apply an X-shaped pattern of thermal paste on the chip. The mounting pressure will still spread the paste sufficiently. Be careful not to use too much thermal paste.

I replaced my thermal paste, but CPU/GPU temperatures are still high. What should I do?

Check that the cooler is mounted with enough pressure on the CPU/GPU. If temperatures remain high despite proper installation, the issue may lie with the CPU/GPU itself.

I'm experiencing the pump-out effect. What should I do?

Thermal pastes with low viscosity are less prone to the pump-out effect. However, this effect can occur with all thermal pastes. Thermal pads made from materials like graphene or carbon are completely immune to the pump-out effect.
