How much time Thermal paste takes to try after applying

(Last Updated On: May 26, 2022)

Applying the thermal paste to your CPU is a simple task that anyone can do. However, it’s essential to know how long the paste needs to dry before use. This article will tell you all you need to know about how long does thermal paste take to dry and does thermal paste dry out in air.

The Different Types of Thermal Paste

There are three main types of thermal paste: conductive, non-conductive, and phase-change. Each has its own unique set of benefits and drawbacks.

  1. Conductive thermal paste is made of metal particles suspended in a liquid medium. It has excellent thermal conductivity but can be challenging to apply evenly. It is also susceptible to drying out over time.
  2. Non-conductive thermal paste is made of silicon dioxide or other materials that are not good conductors of heat. It is much easier to apply evenly but does not have the same level of thermal conductivity as a conductive paste.
  3. The phase-change thermal paste contains a material that changes from a liquid to a solid at a specific temperature. This provides excellent thermal conductivity but can be challenging to apply evenly and expensive.

Which Thermal Paste is the Best?

There are a lot of different opinions out there about which thermal paste is the best. Some people swear by one brand, while others say it doesn’t matter what you use as long as it’s applied correctly. So which is the correct answer does thermal paste dry out in air?

Unfortunately, there is no clear-cut answer. It depends on your individual needs and preferences. If you’re unsure which thermal paste to choose, you could always try a few different kinds and see which one works best for you.

As far as how much time you should wait before testing your new thermal paste, most experts recommend waiting at least 24 hours. This will give the paste time to cure and reach its full potential. Of course, if you’re in a hurry, you can always test it sooner – be aware that your results may not be accurate.

How to Apply Thermal 

Thermal paste is essential for keeping your CPU cool. If you have a laptop, you may not need to apply thermal paste often. But, if you have a desktop computer, you will need to apply it every time you replace the CPU. Here are the steps for applying thermal paste:

  1. Clean the area around the CPU. You will need to remove any old thermal paste and debris.
  2. Apply a small amount of thermal paste to the center of the CPU.
  3. Spread the thermal paste evenly with a credit card or other flat object.
  4. Replace the CPU and screw it into place.
  5. That’s it! Your computer should now be cooler and running more efficiently.

Applying thermal paste is crucial in ensuring that your CPU performs at its best. But how long does it take for the paste to dry? And what can you do to speed up the process?

How long does thermal paste take to dry

Thermal paste typically takes around 24 hours to dry completely. However, you can do a few things to speed up the process. Applying a thin layer of paste and using a hairdryer on low heat can help the paste to dry more quickly.

If you’re in a hurry, you can also try using an accelerant such as alcohol or acetone. However, be sure to use these sparingly, as they can damage your CPU if used excessively.

Does thermal paste dry out in air

Don’t leave too much thermal paste in air it requires pressure or must be closed in some sort of container in order to use it else it will became hard.


Applying thermal paste is a process that can take some time to get right, but it’s worth it. After applying the thermal paste, you’ll need to wait for it to dry before using your computer again.

Depending on the type of paste you use, this can take a few hours to a few days. But once it’s dry, your computer will be able to run cooler and more efficiently.
