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 eloquently 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.

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 which can sustain the heat conduction without messing up with the performance?


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 mention, 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.
