Persistent Overheating After Applying New Thermal Paste (Fixed)

Are you experiencing Persistent Overheating After Applying New Thermal Paste? Spreading it out will make air bubbles in the thermal paste, which makes it less effective at moving heat between the processor and the heat sink. Instead, it would help if you let the heat sink and spread it out, which helps make an even layer of the compound with no air bubbles.

Persistent Overheating After Applying New Thermal Paste

Even though most modern computers are pretty durable, they still have some fragile electronic parts necessary for them to work well. You might worry about overheating if you do things that put a lot of stress on the microprocessor and other parts. Thermal paste is one way to fix this problem. In the next section, we’ll answer some of the most common questions new users have about thermal paste.

Why Persistent Overheating After Applying New Thermal Paste

Can Overheating Be Caused By Using Poor Or Dried Thermal Paste?

People who construct or alter their PCs frequently use thermal paste, and the issue of “poor” thermal paste and what it might do to the computer’s components frequently arises as a question. Some people are concerned that dried-out or outdated paste can cause more damage than benefits. Here, there are a few important things to remember.

Thermal paste’s main objective is to remove heat from the various components in computers and game consoles. We don’t want these items to burn out because they generate a lot of heat while performing their functions.

The thermal paste may not be capable of transferring heat effectively if it dries out too much. If this occurs, your computer’s components might not receive the necessary cooling. Because of this, it is likely that in these uncommon situations, “poor” or extremely dry thermal paste will fail to siphon heat, leading to a buildup in the chips.

Although it doesn’t contribute to overheating, it can go wrong in a way that causes it to malfunction. One of the more common outcomes, when thermal paste fails is that your computer or gaming console will turn up its inbuilt fan to compensate for the extra heating issue.

Many contemporary electronics feature shutoffs that will disable them if excessive heat is detected. It is significant to notice that outdated or dried-out thermal paste doesn’t produce any other problems in computerized gadgets besides overheating. Other issues you may have are almost unrelated to your outdated thermal paste. One purpose exists for the paste.

Will Using A New Thermal Paste Fix Overheating?

If your CPU is getting too hot, one of the first things you should do is check the state of your thermal paste. Most manufacturers will tell you that the thermal paste on their product should last between three and five years.

This is true if you buy more thermal paste for your computer or game console. This is a good criterion. But it will depend a lot on many different things. Your computer’s thermal paste might not last as long after this time, but it might still work fine.

If you haven’t replaced your old thermal paste with new stuff in the last three years, you should check how hot your computer gets when running at full speed. If your computer is running high-end games or other tasks at temperatures close to or above 85 degrees Celsius, you might want to change the thermal paste as soon as possible.

If you find that your machine is getting too hot, the first and best thing to do is to replace the thermal paste. This usually fixes the problem. Even though this might not always be the case, it’s a safe bet since this is the main use of thermal paste.

Also, we don’t recommend using a cheap thermal paste. Spending a little more on high-quality items or well-known brands makes sense. Your machine can shut down if it gets too hot and the failsafe turns on too soon.

This could happen the first time the device is turned on or after it has been running for a while. In other cases, you might be dealing with a broken PC. The best thing to do is to use high-quality thermal paste that you know will work.

Is Thermal Paste Still Needed After The Heatsink Has Been Taken Off?

This question’s response is dependent on a few variables. Was the thermal paste brand-new or recently made when you took the heatsink off or put it back on? If so, you shouldn’t have to replace the old thermal paste with a new one.

The difference would be no more than one or two degrees in these cases. You might find this helpful, but you don’t have to do it. Did you move or knock the thermal paste when you took the heatsink off or put it back on?

If that’s the case, you might want to put the paste on again. But that depends on how much things changed when the heatsink was taken off. Again, if your paste is still fresh, you should be able to spread it out evenly where it needs to be.

There’s nothing wrong with being careful and replacing the old paste with a new layer. This may be especially important if you plan to try overclocking once everything is working. Always check how well your machine is working. If your computer isn’t cooling as well as it should, you might want to try the new thermal paste.

What Occurs If Thermal Paste Isn’t Reapplied?

For the purposes of this inquiry, we’ll suppose that your thermal paste has changed in some way and is now outdated, dried out, or perhaps missing entirely.

Keep in mind that thermal paste’s sole purpose is to absorb most of the heat generated between the sink and the microprocessor.

Lack of thermal paste might raise the danger of components overheating if you must operate your computer at high settings for whatever reason. This will either result in a shutdown to safeguard the device, or it might eventually fail.

In your particular situation, thermal paste might not be essential if you only ever operate your machine at the lowest settings. It is not advised that you skip applying thermal paste again because it is likely that you may need to utilize your computer more intensively at some points.

In other words, more air bubbles between the CPU and the heatsink if there is no thermal paste. These openings could catch debris that interferes with how well your computer works. It won’t be as effective at sucking heat, either.


Did you fix Persistent Overheating After Applying New Thermal Paste? If used appropriately, thermal paste is a great product with a specific function that can work extremely effectively. Although it won’t resolve any fundamental problems with your computer, it is frequently the quickest and most effective way to address an overheating issue.

Frequently Asked Questions

What occurs when the thermal paste is used improperly?

If the thermal interface material (TIM, the actual term for paste) is conductive, using too much will short out your MOBO in addition to creating a mess. If too much TIM is present, it may not compress thin enough to effectively transfer heat, even if the TIM is not conductive (such as Arctic MX-4, for example).

What occurs if too much thermal paste is added?

Too much thermal paste might behave as an insulator when used. In the best case scenario, this might render the paste useless, and in the worst case scenario, overheating could cause component damage. Make sure to paste your component with a thin layer of paste.

How long does thermal paste take to absorb?

Based on how often you use it, you shouldn’t need to reapply for 3 to 6 years, if ever. It takes action immediately but depending on how frequently you use your PC; it may take weeks for it to heal fully. You applied it incorrectly or mounted the cooler incorrectly if it’s running more than a few degrees Celsius hotter.
