Thermal pastes

If you are searching for the best thermal paste for the CPU, you can find so many brands claiming to be the most effective. You must choose the one that best suits your needs. Below are some things to consider when looking for the best thermal paste for the CPU.

First, you must determine your requirements. The type of use, the temperature, the working time and the environment must be considered.

When determining the need, you must determine which surface would fit your needs. There are different types of thermal paste on CPU including gel, solid, and liquid.

Second, the brand name is also significant. There are lots of manufacturers in the market and some of them are well known. You can identify a good brand name from the prices and the quality. Price should not be the only consideration because quality and performance are equally important.

Third, the texture affects the function. The type of material determines how the heat is absorbed and dispersed. If you want the system to be efficient, you should choose the one with better heat conduction. If you want better thermal paste life, choose the one with the larger surface area.

Fourth, compatibility with different platforms is important. This means that the thermal paste can work effectively on all sorts of computers. However, it is very important to test the paste on your system first before using it regularly. Compatibility should be ensured even if the manufacturer recommends using the particular paste on your system.

Fifth, ease of use is very important. You should find the thermal paste very easy to use. It should not need any special effort to use it. Besides, it should not produce any undesirable results. If the paste is too difficult to use, the users will find it difficult to use it as well.

Sixth, you should look for the warranties offered by the manufacturer. There are high-quality thermal paste manufacturers that offer long warranties. This will help you get your money’s worth, especially if you need the product for a long time.

Lastly, it is recommended to shop around before making a purchase. There is much Thermal Paste for the CPU available in the market today. Make sure to choose one that is made from quality materials. Also, make sure to check whether the manufacturer offers customer service for assistance.

As we have discussed above, thermal paste for the CPU is used to improve the performance of your PC. However, it is also used to prevent your system from overheating. When you are using thermal paste, your PC will work more smoothly and effectively. To make use of this advantage of thermal paste, you have to make sure that you apply it properly.

First, let us look at how thermal paste on CPU works. When you use thermal paste, the heat sink of your PC will be covered with heat-absorbing paste. The heat-absorbing paste will then trap the heat that is produced by your CPU. It will help to keep your CPU much cooler during use.

Second, you need to ensure that the heat-absorbing material is thick enough to catch the heat that is produced by the processor. Otherwise, the thermal paste may not be able to do its job properly. Usually, thermal paste is made of aluminum and copper. However, you can use other materials that are just as effective, such as silicon or other materials that have a high thermal conductivity.

Third, you have to understand that thermal paste works well with air cooling systems. However, it does not work well with water cooling systems. If you are planning to use one of these systems, then you might need to purchase some additional fans to use along with the thermal paste. It will allow your CPU and other components to stay cool while you are working.

If you want to use thermal paste for the CPU, you have to understand how it works so you can make better use of it. You can purchase thermal paste from several different places. However, you have to be sure that you get a genuine thermal paste. You do not want to end up wasting your money on an ineffective product. You can use this guide to help you make the right decision when purchasing thermal paste for your CPU.

What Is Thermal Pastes?

Thermal paste is a substance applied between the processor and the heat sink. You can buy small tubes of thermal paste at electronics stores, sometimes accompanied by a small shovel-like tool called an applicator.

When you’re building a PC, you will need a tube of thermal paste for your PC to run smoothly. Some CPU heat sinks come with thermal paste pre-applied to them so you can install it and go. Some hardware enthusiasts, however, will swear by and manually apply their favorite brand of thermal paste.

The role of thermal paste is to help transfer heat away from the CPU and into the heat sink. The heat sink then expels the heat away from the hardware. This keeps the CPU cool, especially when it’s hard at work processing tasks.

You may also find the term “stock thermal paste.” This kind is thermal paste applied by the manufacturer, such as on a pre-built machine. However, some manufacturers skimp out on the thermal paste and use a compound that’s not very effective at conducting heat.

Working of Thermal Pastes

CPUs can get very hot, so it’s essential to draw heat from them as quickly as possible. Unfortunately, the air is a terrible conductor of heat, so there needs to be as little air as possible between the CPU and the heat sink for optimum transfer.

If you have prodded around inside a computer, you will know that the heat sink presses tightly against the CPU. This seal may seem good enough to stop air from getting in; unfortunately, even a tight squeeze is not enough to keep air out.

The surface of the CPU and the heat sink’s contact plate is covered in tiny grooves and gaps. If not properly sealed up, these gaps allow air between the processor and the heat sink, reducing the heat transfer efficiency between the two.

This is where thermal paste comes in. Not only is thermal paste a good conductor of heat, but it can get into those small gaps and grooves on the surfaces of the hardware. This creates an air-tight seal and increases the rate of heat transfer.

Over time, the thermal paste will get old and dry. The dryness reduces its effectiveness and causes the CPU to get toasty. This occurrence is why people suggest re-applying the thermal paste to prevent a computer from overheating.

Types of Thermal Pastes

Thermal pastes and greases can vary in many different ways. To start, there are several different kinds of thermal paste, such as silicone, graphite, liquid metal, ceramic, and carbon-based types. Thermal pads also exist, and although these have been inferior to thermal grease for many years, solutions that can perform equally to thermal grease have started to appear on the market.

In our lineup, we feature mostly ceramic-based thermal paste, which is the most affordable type and the easiest to apply, while also being very effective. Still, some carbon-based and liquid metal thermal greases made our best picks list, too. We also feature one thermal pad in this article.

Keep in mind that thermal paste on CPU compositions tends to vary between manufacturers, too. Each manufacturer closely guards the secrets of their own paste’s formulation, and some work better than others.

Ceramic thermal paste is made from? Did you guess it? ceramic. This paste is thermally conductive but not electrically conductive. As such, they’re the easiest and safest to apply to your processors. They’re also the most popular, and they tend to be affordable, too.

Metal, on the other hand, is both thermally and electrically conductive. As such, liquid metal thermal pastes can be dangerous if not applied correctly.

While liquid metal thermal grease is easily the most effective of the thermal greases available today, if you spill even a little bit on the other components of your PC, you could cause unwanted damage. It’s also far more expensive than the other types of computer thermal paste we feature here. As such, liquid metal thermal pastes can be dangerous if not applied correctly.

Carbon-based thermal pastes are similar to ceramic thermal pastes in that they are thermally conductive, but not electrically conductive. Carbon-based thermal pastes also apparently have a longer shelf life than other types of thermal paste.

Thermal pads come in several different materials, but the most common are silicone and graphite. These pads are firm at room temperature, but once the CPU hits higher temperatures, they soften, melting into the air pockets between your heatsink and CPU.

Some thermal pads are even reusable, meaning you can keep the pad if you upgrade your CPU or heatsink. Thermal pads have historically been unable to compete with thermal paste and grease in terms of cooling performance, but this has started to change.

Do You Necessitate Thermal Paste?

You may think that thermal paste is not as essential in a PC build as the processor or power supply. While a computer will boot without thermal paste, the problem will be keeping it alive while you use it!

Without thermal paste, there is not optimal heat transfer between the CPU and the heat sink. As such, the CPU gets a lot hotter than it would be if you had used paste. If the CPU gets too hot, it will overheat; this results in stuttering from throttling, blue screens, and random shutdowns.

While buying thermal paste is the least exciting part of a computer build, it is a must-have. It allows the heat sink to do its job better and protects your computer from burning out and shutting down.

If you’re wondering if you need thermal paste because you are worried about messing up your brand new expensive processor with gray goop, try getting a heat sink with paste pre-applied. The paste may not be the best kind on the market, but it does make installation easier.

How to Apply Thermal Paste?

Given the importance of thermal paste, there is a disturbingly volatile debate on the best way to apply it. If you scour the internet, you will find theorems, strategies, and passed-down advice for application.

The simplest method of application is to place a pea-sized drop on the middle of the processor. Then, attach the heat sink to the processor, applying pressure on the four corners equally. It ensures the thermal paste is squashed and distributed evenly along the surface.

If your thermal paste comes with an applicator, you can use it to get an even spread of paste. Some people like this method to ensure the spread is perfect before they clamp the heat sink down on the processor.

Some methods talk about a line-based application that spans across the cores of the processor. Of course, you will need to know where the cores are on the processor, so it is not for everyone.

It is great for studying different ways and choosing the method that suits your hardware best.

Regardless of what method you choose, it’s essential to ensure no bubbles or gaps occur in the paste. These allow pesky air to get in and hinder heat distribution.

Thermal Paste Performance Rankings

Here is the complete list of our recent testing done on thermal pastes. Furthermore, we will add the new and popular thermal paste to the list in the future. Here, you will discover the original test done on various pates of about 85. Based on performance and price few of them were listed below.

From here, you will get a better view of the thermal paste and working principles of the products. Here is the analysis of how we test certain thermal pastes, but the important takeaway here is that a single thermal mixture can act differently based on different variables, such as what sort of cooler and fix you use. To embrace all the bases, tested each thermal paste with three variable factors,

  • Low-tension Noctua NH-D15 scaling to mold an air cooler without a backplate
  • High-tension Noctua NH-D15 scaling to mold higher-end air coolers with a backplate
  • High-tension mounting with an AIO liquid cooler

Based on the temperature difference with the thermal paste during the standardized test bench, and as ever, lower temperatures are reliable.

Wrap-Up

Cooldown the CPU using the best thermal pastes, The stock thermal paste that is often bundled with the CPU coolers is certainly not even close to the best ones you can get your hands on. If you feel like your processor is running pretty hot, even at a low ambient temperature, you should certainly consider investing in a good thermal paste. Even if you have a laptop, you should consider getting the thermal paste replaced by an expert technician, as the compound used by the manufacturer is usually of average quality and not applied properly.

Well, there are plenty of options to choose from. Depending on your budget and performance demands, you could choose between normal grease-based or liquid-metal-based thermal compounds. We suggest you go for liquid metal only if the slightest temperature difference matters a lot to you. Otherwise, it’s not worth the risk at all.
