A thermal paste acts as a highly conductive medium between the hot surface of a CPU/GPU and the heat sink which is further connected with the fans to provide necessary cooling action. Thermal paste is crucial for the working of a computer, and you cannot use a computer for more than 5 minutes without thermal paste as the CPU will overheat and shut down the computer altogether. If you want to apply fresh thermal paste on your new system, or simply reapplying it on an older one, consider the following aspects before you buy one.Thermal Conductivity: The thermal conductivity of a thermal paste represents its capability to transfer heat from one surface to another. The conductivity is available in the W/mK unit where higher is always better.Included Quantity: The thermal paste is packed in a syringe before shipping and it is available in a certain quantity per syringe. Generally, you will get a few grams of thermal paste per syringe that you can apply to your CPU.The density of The Paste: The thermal paste is in a semi solid state which makes it kind of difficult to apply. If the density of paste is too low, it can slip past the surface and enter the CPU socket and potentially damage the CPU socket permanently.The thermal pastes that you are going to find on our list of the best thermal paste are carefully curated on the basis of above mentioned factors and a few more essential characteristics. If you want to know more about thermal pastes, make sure you take a look at our “Buying Guide” for the best thermal paste available later in the article.

Every electronic product that deals with flow electrical current also has to deal with rising temperature. The rise in temperature is quite high in parts like the CPU and GPU that have the highest load on your computer.Hence, dedicated cooling systems are provided for these peripherals so that the temperature can be controlled. But for the efficient performance of the cooling system itself, you need a thermal conductivity catalyst called a thermal paste on the surface of the CPU/GPU chip. Here are some important specifications of a thermal paste that affects its performance and the overall thermal status of your computer.Thermal ConductivityAs we are discussing the factors that affect the performance of a thermal paste, let’s talk about the most crucial factor first which is its thermal conductivity. The thermal conductivity of any fluid is basically its capacity to conduct the heat from one end to another. In the case of computers, the thermal paste is applied between the CPU and heatsink so that it can quickly absorb heat from the CPU and push it towards the heat sink for further heat dissipation.The thermal conductivity of a thermal paste is represented in the W/mK unit where higher thermal conductivity rated options are generally better. But, you also need to consider your cooling system before you buy a heavy duty option. There is no point in getting a 15 W/mK thermal paste if you are applying it over a stock cooler that has very limited cooling performance.Quantity of Thermal PasteThe quantity of thermal paste available in the package should only concern you if you are planning more than one application with the paste. In any thermal paste pack, you will be getting at least 2 grams of paste available in the syringe that can easily get multiple applications performed with ease.Any less than that would be a problem as it won’t allow you to do overs if something goes wrong the first time. Also, you should be able to store the thermal paste securely if there is an ample quantity available in the package that you cannot use at once. The best way to store thermal paste is to keep it as it is in the syringe itself and keep the syringe locked in an airtight container. Having multiple syringes helps in such a case as you only need to open one at a time for an application.Thermal Paste CompoundThe chemical compound of a thermal plays an important role in its performance and stability. There are a lot of different chemicals used by different brands to make a thermal paste by which they manage to achieve a certain level of thermal conductivity and provide that at a certain budget. Generally, you should take a look at reviews of previous users if you want a quick idea about the stability and useability of the thermal paste.You can also look into the compounds used in the making of the thermal paste to make sure that there are no harmful compounds used that can be hazardous for the system. The thermal paste compound needs to be thermally conductive and electrically non-conductive for best performance.TDP of Your SystemTDP stands for the thermal design power of a system. You will be more familiar with this term if you own a laptop instead of a desktop computer as TDP is used to determine the input requirement and power capacity of the laptop. While buying a thermal paste, you should consider examining your system and calculate the average TDP of your CPU or GPU and make sure your thermal paste can suffice its requirements. For higher TDP, you will be needing a high quality thermal paste whereas a standard option will be good enough for mid-range builds. The TDP rating of your system also helps you to determine the suitable temperature range that must be supported by your thermal paste.ConclusionMost people prefer high end thermal paste bought separately for the application. Also, you would need a thermal paste in case you are cleaning your computer and willing to reapply the paste to increase the temperature statistics of the CPU. In any case, you will find the best thermal paste on our list today. If you are not sure which option is right for you, look at some of the best options available below.High thermal conductivity is crucial for heavy load applications. If you are using your computer for longer sessions, the SYY 2 CPU Paste Thermal Compound Paste is going to be perfect for your needs. While SYY only provides 2 grams of paste in every package, you will be getting a thermal conductivity of 15.7 W/mK, which is best in comparison.Talking about the quantity of thermal paste, Thermal Grizzly beats all other choices by offering a large 5.55 grams syringe full of Thermal Grizzly Kryonaut Thermal Paste. It has a high thermal conductivity of 12.5 W/mK and is suitable for multiple applications for the same of different computers.Lastly, we will recommend the Noctua NT-H1 Thermal Paste as the best value for money option from our list. Noctua is known for premium yet reliable and high performance products and the Noctua NT-H1 is no exception for that. You will be getting 3.5 grams of thermal paste with a suitable temperature range of -50°C to 110°C that covers standard as well as gaming computers.Related Posts:How To Clean Thermal Paste Off CPUHow to Apply Thermal PasteWhat is a Heat Sink?

Dried or “cured” thermal paste can lead to serious cracking and a loss of heat transfer ability.
Does changing old thermal paste make a difference? ›
If your use is easier going and you're using quality pastes, you should only need to change it every couple of years. In general, changing thermal paste every one to two years is a good idea. However, we would not recommend relying solely on timeframes to monitor when you need to change your thermal paste.Do I apply thermal paste to CPU or heatsink? ›
Ideally, applying the thermal paste will be the last step before mounting your heatsink. Make sure you place your cooler on as straight as possible the first time. If you have to turn it to line up the holes after it's already place, the thermal paste will not spread properly.Is thicker thermal paste better? ›
A high-viscosity thermal paste, on the other hand, behaves more like a solid. It doesn't flow that easily and could be harder to spread using a spreader or spatula. But — it sits better on the CPU once you have applied it correctly. Simply put, you don't want a paste that's too thin or too thick.What is the best CPU paste pattern? ›
The “Five Dots” method is a variation on the previous pattern as it applies 5 dots evenly to the CPU. This is the recommended method for beginners as it evenly distributes thermal paste to most of the CPU, including the middle, and also has a low risk of spillage.What is a common mistake when applying thermal paste Why? ›
The most common mistake is using too much thermal paste. Excess thermal paste interferes with and spoils the correct heat dissipation. Additionally, there is the possibility of paste spilling over to the outside and placing the system in danger.Should I use spatula for thermal paste? ›

To prevent this, you should store your thermal paste in a cool and dry place, away from direct sunlight, radiators, or other heat sources. Ideally, you should keep it in an airtight container or a ziplock bag to protect it from dust and moisture.
Clean the paste from the CPU using isopropyl alcohol and a cloth. Keep the CPU in the socket and gently remove the paste. Don't be heavy handed and take your time. Any paste in recesses can be cleaned using a cotton swab.Can too much thermal paste overheat? ›
Yes. A dried-out thermal paste can cause overheating. A traditional thermal paste is made out of an organic solvent, as well as a heat conductor. The solvent serves the purpose of filling in all the air gaps between the heatsink and the CPU, while the conductor transfers the heat between the two.
