Best Thermal Paste FAQs

Best Thermal Paste FAQs

What does thermal paste do?

Thermal paste is used to join a heat sink to the device it is meant to cool. The heat sink is designed to remove heat from the sensitive electrical equipment, the thermal paste smoothes the surface of the heat sink and allows it to work at maximum efficiency.

Choosing the best thermal paste for your specific application is essential.

How do you apply thermal paste?

Start by knowing where the component goes on its circuit board. Then, put a drop of paste on the side of the component that will touch the circuit board. Push the piece into position, pushing down on the component where the thermal paste is.

That should suffice although you can lift the component to verify it spread properly. If it didn’t simply wipe the paste off and try again.

How much thermal paste should you use?

You don’t need a lot of thermal paste, what you do need is a complete layer on the surface of anything component. It should be enough just to add a dot to the surface of each side of your component, it will spread itself out properly.

How do you remove excess thermal paste?

Wipe the thermal paste off the surface with a lint-less microfiber cloth. Alternatively, you can use a coffee filter. This will prevent the component from becoming damaged and allow you to apply a new layer of the best thermal paste for the job.

Does thermal paste have an expiry date?

No, thermal paste that remains in the tube is good to use whenever you need it. You may need to purchase several different types to get your computer build completed properly but as long as the tube is closed after use, it will keep indefinitely.

However, always test a little first, if it doesn’t look like paste it has gone bad.

How long does thermal paste last?

Most suppliers recommend changing or replacing the thermal paste after 5-7 years. In reality, that means that most users will have replaced or already upgraded their computers in that time.

Where is best to buy thermal paste?

Amazon! You can purchase thermal paste in a variety of stores but Amazon allows you to see the product, its values, and specifications. This will help you to make an informed choice and select a thermal paste that will do the job perfectly.
