Best Thermal Pastes/Compounds in 2021

Best Thermal Paste

Do you want to see your components on fire?

Obviously, no one will want to go through such a dreadful sight. And to prevent such a situation, we have thoroughly discussed the steps to take. 

Furthermore, must have a look at the *How often should we change the Thermal Paste?* section to know the must-steps to take…

Background

Components like GPU and CPU come with an integrated device known as “Heatsink”.These heatsinks are passive coolers, which help in eliminating the heat.

They make use of compressed air or liquid coolants to dissipate the generated heat and lower the component’s temperature. When you buy a component, there’s this guide that possesses every bit of information regarding the hardware.

Whilst shuffling through the pages, you must have stumbled upon a safe temperature zone. To achieve those safe temperatures, a liquid coolant, or a semi non-conductive liquid is used. That semi non-conductive liquid is known as thermal paste.

Before proceeding toward the product review session, kindly look at the types of thermal paste that you can use on your components:

  • CERAMIC: It’s the most common type of thermal paste you can stumble upon. It makes use of suspended silicon particles and is usually thick. Not to forget, the same thermal paste comprises fine ceramic powder which allows it to reduce the temperatures.
  • CARBON-BASED: We all are aware that the diamond is a form of pure carbon. Well, the carbon-based thermal pastes are usually the best considering that the thermal conductivity is at an all-time high due to powdered diamond particles.
  • THERMAL-GREASE: The actual essence resides within the thermal grease ingredient. The majority of the pastes use this compound, but the composition greatly varies. The pastes, which are explicitly based on the thermal-grease compounds are the best because you will get a better temperature as compared to previous temperatures.
  • LIQUID METAL: Well, be cautious when using liquid metal thermal pastes because they are largely conductive. If by any chance, you spill some of it on your CPU, or any other transistor, or component, there you go, your PC might die due to internal electric conduction.

These are a few thermal pastes to look at before diving into the buying process. The list is as follows:

What is a thermal paste and how it works?

The notion behind the manufacturing of such products is to lower the device’s temperature. Thermal pastes are designed in such a way that it dissipates heat quickly without damaging itself.

The thermal paste is applied between the heatsink and the device so that the air which is sliced in between the two parts is no more there.

Unfortunately, Air is not a conductor of heat. It sorts of traps the heat. When the heatsink is unable to spread out the heat from the device, its performance downgrades.

To eradicate this problem, thermal paste lines up the surface as per the requirement without any trapped air. This, in turn, helps the heatsink dissipate heat at a larger rate resulting in a boosted performance. It might sound difficult at first, but it’s really not considering that all thermal paste does is keep the temperature low and give your components breathing space from hot air.

Apart from this, do bear in mind that you can interchange the types of thermal paste depending on the type of component available. There’s no hard and fast rule when it comes to procedural testing, so go ahead with whatever your heart speaks of.


How often should you change the thermal paste?

To prolong the longevity of the device’s performance, you will have to ensure that the thermal paste remains intact for a longer period of time.

The reason for changing thermal paste is nothing, but to give a boasted thermal conduction between the heatsink and the device.

What happens is that, when you buy a new processor or a GPU, the stock cooler which comes with the component has a rusted thermal paste applied to it.

These thermal Compounds have a shorter life span and dry out easily. So, isn’t it better that you apply the best thermal paste on the CPU/GPU as frequently as possible which can sustain the heat conduction formula without messing up with the performance?

Conclusion: 

All in all, if you are a dedicated overclocking fanatic, then there’s only one paste for you.

It’s Thermal Grizzly Conductonaut. Why? Due to its groundbreaking thermal performance of 73W/mK which is double the conduction provided by Coollaboratory liquid ultra.

Not to forget, they have surfaced in the markets long before any product and have won the hearts of millions of people.

It is preferred that you go along with Grizzly thermal pastes because they are resilient, efficient, and provide the best dissipation rate.
