How Long Should I Wait After Applying Thermal Paste? Guide

This post explains How Long Should I Wait After Applying Thermal Paste? Arctic Silver 5 needs to be powered on for up to 200 hours to cure; in other words, the process takes up to 200 hours (the maximum temperature could be a couple of degrees lower). AS5 works great with an i7-3770 because of how cool that CPU runs.

Anyone may perform the simple job of applying thermal paste to your CPU. It’s crucial to understand how long the paste must cure before usage, though. You can learn everything you need to know about how long thermal paste takes to dry and whether thermal paste dries out in the air in this post.

How Long Should I Wait After Applying Thermal Paste?

Depending on how long it takes for Artic Silver 5 to cure, it can take up to 200 hours. The cooler’s attachment takes how long? That pretty much represents the maximum. Thermal paste does not require “curing,” unlike carpentry glues.

Should I Wait After Applying Thermal Paste

It merely creates a thermal barrier to help heat travel between the cooler’s heat sink and the heat source (the IHS for the CPU or GPU). Although the IHS and cooler’s heat sink feel smooth to the touch (possibly except for the embossed writing), they are everything but smooth at the microscopic level.

These minute imperfections are filled in by the thermal compound, which also creates a smooth surface between the two. To improve the compound’s performance, you may “lap” the IHS by smoothing it on 2000, 3000, or 4000-grit surface (do the same to the cooler’s heatsink).

However, unless you’re moving into the world of “liquid metal,” which is extremely challenging to work with because it is electrically conductive and mistakes might destroy your electronics, it rarely pays off to put in the effort. Most thermal compounds are not electrically conductive. Hence their popularity is based more on usability than thermal efficiency.

Different Types Of Thermal Paste

The three primary varieties of thermal paste are phase-change, non-conductive, and conductive. Each has a special set of advantages and disadvantages of its own.

  1. Metal granules suspended in a liquid media are used to create a conductive thermal paste. Despite good thermal conductivity, applying evenly might not be easy. Additionally, it is prone to drying out with time.
  2. Silicon dioxide or other materials that are poor heat conductors are used to create a non-conductive thermal paste. It has far less thermal conductivity than a conductive paste but is much easier to apply evenly.
  3. The phase shift A substance in thermal paste transforms from a liquid to a solid at a particular temperature. While offering good thermal conductivity, this can be pricey and difficult to apply evenly.

What Is The Best Thermal Paste?

Regarding the best thermal paste, there are numerous competing viewpoints. Some people will only use one brand, while others will use any brand as long as it is used properly. Which of the following is true regarding whether thermal paste dries in the air?

Unfortunately, there isn’t a simple solution depending on your requirements and preferences. You may always try a few various types of thermal paste to see which one works best for you if you’re unclear about which one to use.

Most professionals advise waiting at least 24 hours before testing your new thermal paste. The paste will have more time to cure and realize its full potential as a result. Of course, you can test it sooner if you need to, but keep in mind that your results might not be reliable.

How To Apply Thermal?

The use of the thermal paste is necessary to keep your CPU cool. The thermal paste may not need to be applied frequently if you have a laptop. However, if you have a desktop computer, you must use it each time the CPU is changed. The steps for using thermal paste are as follows:

  1. Clean up the vicinity of the CPU. It would help if you swept up any leftover thermal paste and debris.
  2. To the CPU’s center, apply a thin layer of thermal paste.
  3. Using a credit card or another flat device, evenly distribute the thermal paste.
  4. Screw the CPU back in place after replacing it.
  5. I’m done now! Now, your computer ought to be performing cooler and more effectively.

Applying thermal paste is essential for maximizing CPU performance. How long does it take the paste to dry, though? What can you do to hasten the process, then?

How Long Does Thermal Paste Take To Dry?

It normally takes 24 hours for thermal paste to dry fully. However, there are some points you may make to quicken the process. The paste will dry more rapidly if only a thin coating is applied and a low-heat hair dryer is used.

If you’re in a hurry, you can also try using an accelerant, such as acetone or alcohol. Use caution when using these, as they can harm your CPU if used excessively.

Does Thermal Paste Degrade When Expose To Air?

Avoid exposing thermal paste to excessive air since it needs pressure to be used or must be contained in some way to prevent it from drying out.


Ended with the topic How Long Should I Wait After Applying Thermal Paste? Applying thermal paste properly can take some time, but the effort is worthwhile. It would help if you waited for the thermal paste to cure after applying it before using your computer again.

Depending on your paste, this can take a few hours to a few days. Your computer, however, will be able to operate cooler and more effectively once it has dried.

Frequently Asked Questions

How long should thermal paste be let to dry?

You may practically turn on your PC as soon as you apply the AS and don the HSF unit. But for the AS to operate at its best, you must give it 24 to 48 hours of genuine PC use.

How long does it take for thermal paste to dry?

In most circumstances, you can use it immediately away, but I often advise giving the compound an hour or two of low-impact use to bed in. Most decent compounds, including all “thermal grease” varieties and arctic silver, do not dry.

How much time does the new thermal paste take to set?

Thermal paste is said to require 200 hours to apply and accomplish its task properly. Does this imply that, up to a point, the longer the thermal paste is on the heatsink, the increasingly cooler my machine will become?

Does thermal paste resemble glue?

The texture of fresh thermal paste resembles toothpaste in certain ways. But over time, it might harden and take on the characteristics of glue. However, it facilitates the fastest possible heat flow from the CPU to the heatsink.
