best thermal paste

Best thermal paste is an exceptionally electrically conductive layer between the hot surfaces of a CPU or GPU with the heat-sink, which is connected to the fans to supply the necessary cooling. Best thermal paste is vital to the operation of computers, and it is impossible to run a computer longer than five minutes without best thermal paste, as the CPU can overheat and close down the computer. If you plan to apply a new best thermal paste on your brand new computer or simply use it for an older system, be aware of the following points before purchasing one.

Factors To Consider

Thermal Conductivity

Thermal conductivity in a paste is the ability in transferring heat from one area to another. The conductivity is measured in the unit W/mK, where the higher value is always superior.


The best thermal paste is semi-solid, making it challenging to apply. If the paste density is too low, it can slip past the surface and enter the CPU socket and potentially permanently damage the CPU socket.

Included Quantity

The best thermal paste comes packaged inside a syringe before the shipment and is sold in a set amount per syringe. In general, you’ll get just a few grams of paste in each syringe, which you can put on your computer.

The best thermal paste you will discover on our list of top best thermal paste have been chosen based on these factors as well as other essential qualities. If you’re interested in learning more about the properties of the best thermal paste, be sure to go through our list of the most effective thermal paste further down the page. Be sure to go through every option thoroughly to determine the most suitable option within your budget.

What About Thermal Paste ?

Best thermal paste (also often referred to in thermal oil or thermal compounds) serves as an agent to transfer heat onto the CPU’s heat spreader and IHS (Integrated Heat Spreader). The base compound is zinc oxide.
The machine produces plenty of heat. It has so much that you could fry eggs in it.
That is a problem, as excessive heat can cause irreparable damage to components extremely quickly, specifically processors and graphics cards that are high-end. To prevent this from happening the issue, we’ve got heat sinks.

Air Based Heat Sinks

The term “heat sink” refers to the thing you place on the CPU to transfer heat to it and keep it cool. It’s set on top of a CPU temperature spreader, an IHS (integrated heat spreader). The traditional air heat sinks feature the base of metal that connects to the processor. The heat is transferred to the metal block and is usually channeled into copper pipes. They are connected to thin metal fins, with fans blowing over them to disperse the heat further.

Water Coolers

Water Coolers operate using the same principle. The heat sink is placed on the top of the AMD or Intel processor and has water flowing over it (sound scary, isn’t it?). That causes the water to heat up and get funneled into the radiator. The radiator has channels as well as metal fins that are attached to it. Some fans blow against the fins made of metal. That cools the water before it travels back into the cooling unit of the CPU.


That is how thick or thin it is. Its higher viscosities are denser, and like the real thing, they tend to stick better to the heat sink in your computer.
Low viscosity thermal pastes are more fluid and eventually dry out within a few days of being the application to allow for setting. It is important to note that a less dense thermal paste could spill onto your motherboard easily if used too often.

Specific gravity

Specific gravity refers to how dense and heavy the paste’s weight is and is generally not mentioned on most best thermal paste. It’s not often taken into account. The specific gravity is measured in grams for every cubic centimeter.

Thermal Design Power

Your processor’s TDP will inform you of the amount of power it draws. It can be used to estimate the degree of heat it will become. The ones with more TDP will require greater power, which will generate more heat.
It is a factor to take into consideration when selecting a thermal paste. A hotter processor will require an appropriate best thermal paste to meet it. You will find this number in your processor’s specifications under TDP.

Ambient Temperature

The air surrounding your system may be a significant factor in the degree to which your system operates cool (or cold). If you reside in a region where the temperature is always hot, you may want to upgrade the best thermal paste you use.
The air inside your system around your processor may influence the results too. If other components are at a high temperature (say, your GPU), this air could affect your system to the extent that the temperature outside could.

Asked Questions

1. Which one of the thermal pastes is suitable for laptops?

There are various thermal paste options available on the market that are suitable for GPU and CPU on laptops and desktops. A few of the top laptop thermal pastes include Thermal Grizzly Kryonaut, ProlimaTech PK-3 Nano Aluminum Cooler Master MasterGel Professional V2, Arctic MX-5, Noctua NT-H1, Gelid GC-Extreme.

Is it worth purchasing Thermal Paste?

If you’re making a new computer or upgrading an existing PC with a new processor or maintenance on your desktop or laptop, you should consider adding a brand fresh Thermal Paste to your CPU, and GPU is among the first things you should do. For new systems, even though CPU coolers are pre-applied with thermal compounds, it is recommended to use your thermal Paste from a higher quality brand. A quality thermal paste can aid in transferring heat to the more excellent/ heat sink and aids in keeping CPU temperatures low.

2. Can I use toothpaste to make thermal Paste?

The principal function of thermal Paste is to improve the temperature conductivity between the processor and heatsink. There are various Thermal Pastes on the market, and some excellent options are pretty inexpensive. Therefore, make sure you use a good thermal paste even if it’s less expensive and doesn’t use toothpaste since it can cause damage to your equipment.

3. How do I determine how much thermal Paste to apply to my computer?

As a guideline it is suggested that you use a pea-sized quantity of thermal Paste to the middle of the processor. It is not necessary to apply the Paste uniformly, but let the heat sink spread the thermal Paste across all surfaces. That ensures that the Paste is distributed evenly and doesn’t go over the flow limit.

4. How often do I need to replace thermal Paste?

Most of the time, you won’t need to change the thermal Paste is often. If properly applied, it will last for a few years. However, if you notice an increase in CPU temperatures, it is advised to change the thermal Paste and clean the fans and vents correctly.

5. Can we fabricate thermal Paste from scratch?

Thermal Paste is a chemical compound specifically designed to improve the thermal conductivity of CPUs GPU, CPU, and other electronic components. There are several ways to make the thermal Paste yourself by utilizing essential household items in times of need. Standard methods include mixing the toothpaste with Vaseline or hazelnut and cocoa cream Vaseline and aluminum powder. We recommend you purchase a thermal paste specifically designed for use, even if it’s an affordable one.

6. What should I do in the absence of thermal Paste?

If you don’t have thermal Paste, we recommend that you hold off building your PC or upgrade until you buy an appropriate thermal paste. If emergencies arise, you may utilize a combination of Vaseline and toothpaste (in the 80-20 ratio). Another option is to use fine aluminum powder that is mixed with Vaseline.

7. If I apply excessive amounts of thermal Paste?

The majority of GPU and CPUs manufacturers recommend using a small amount of thermal Paste. If you are using excessive quantities of thermal Paste, the contact between the CPU and the heatsink won’t be optimal due to large pieces made of the thermal Paste. In the end, your overall temperature conductivity could decrease due to the lower effectiveness in the use of thermal Paste.

8. What happens if we don’t use thermal Paste?

If you do not apply thermal Paste, the space between CPU and heatsink is covered by air. Air is not a good conductor of heat. That means that heat transfer between the CPU and the heatsink will be lower, and CPU temperatures will rise. That can cause thermal throttling, whereby the CPU can slow itself down because of increased temperatures. In the long term, the CPU’s life will decrease significantly because of the high temperatures and could lead to failure shortly.

9. Do I need to remove my old, unused Thermal Paste?

If you’re applying a new type of thermal Paste, it is recommended to take off or clean the old Paste thoroughly. It is not recommended to use a new thermal Paste over the existing thermal Paste because the previous one may be dried out and won’t benefit the new Paste at any point.

10. Do old thermal pastes cause excessive heat?

Old thermal Paste lasts for a couple of years (usually 3-4 years), and then it needs to be replaced to improve thermal conductivity. If you keep using an old thermal paste, you will not effectively transfer heat from the CPU to the heatsink. As a result, it can cause overheating of the CPU.

11. What is the best way to wash Thermal Paste?

It is possible to use a microfiber cloth and rubbing alcohol to clean thermal Paste. Rubbing alcohol can be typically ethyl or isopropyl alcohol. However, the majority of thermal paste companies and CPU and GP manufacturers advise using higher amounts of isopropyl ethanol to cleanse Thermal Paste.
