The thermal paste is the most effective heat conductor which is also very capacitive; you must have a clear idea to choose the heatsinks or coolers to fit on your processor. The thermal paste will be very handy to fill even the tiny gaps which may improve the overall cooling and performance, it is also possible to use different types of thermal compounds like silicon, ceramic, metal and carbon-based materials.
If your processor is running too hot even at a low temperature then it is the best idea to use a good thermal paste. It is also possible to apply the paste to laptops because it may not be coated well and it will be constructed with average quality materials.
The most important function of the thermal paste is to spread the heat from the processor or chip to the cooling device. The chips and coolers will not mix together at every spot, so the thermal paste is used to fill the gaps that are not properly connected to the processor then it is transferred to the cooler.
The computers and laptops need a thermal paste for their efficient cooling and consistent performance. The cooling can make your system to work for a long time without any damages; it can be able to dissipate heat for keeping the powerful CPU to be cool.
Most of the thermal paste comes with a specific tool to spread the paste over CPU or motherboard except for a liquid metal paste. The silver-based thermal paste offers a good performance after applying it you may get a better result, but it totally depends on how well you have squeezed the paste throughout the CPU.
Some of the best thermal paste for computer or laptops:

Best Thermal Pastes – Buying Guide
When you have a new processor, you can use it for enhanced gaming, modeling or standard work but you must buy the top quality paste so that the CPU can stay cool without any overclocking or overheating.
When you plan to buy a thermal paste make sure that it has good thermal conductivity, thermal greases play an important role in managing the temperature of a microprocessor in a computer or other electronic devices. They must provide high versatility and reliability to keep the system cool and safe.
Every thermal paste has a good thermal conductivity rating which is nothing but to transfer the heat from the processors to the heatsink. If the thermal conductivity is more than the temperature, then it will be reduced more. There are different units for liquid and non-metallic compounds, actually, the non-metallic compounds will have the conductivity between 4-10W/mK and the liquid thermal paste can have the thermal conductivity of up to 70W/mK.
The thermal paste is a thermally conductive substance that can be applied between the CPU and its cooler which helps to prevent the system from overclocking. If you need thermal paste for just one or two processors then you need not worry about the density or availability of the paste, but every thermal paste will contain enough paste to install your CPU.
To enhance the application process easier you must choose the thermal paste with an adequate amount of density so that it can squeeze easily throughout the CPU. The liquid thermal paste has less density than the normal thermal paste. It must also have an even consistency for applying the paste directly to your CPU or GPU. It should be a carbon-based compound and must be free from electrical conductivity so that it may be easy for you to apply without any short circuits.
When you are ready to apply a thermal paste over the processor or any other equipment you must be careful because it can affect or harm you by short circuits. You must choose a paste with low conductivity so that you can use it without any shorts even if it touches the electrical components.
The best approach to apply the paste is to take a pea-sized amount at the center and allow the heatsink to push the paste on the CPU. This technique avoids spreading of paste over the heat spreader it works well with a less viscous paste. If the thermal paste can conduct electricity then it may lead to the short circuitry. It is very important to choose the product and ensure whether it is conductive or non-conductive, if it is not electrically conductive then it is safe to use.
How Thermal paste works?
Thermal Paste fills even the little gap between the heatsink and processing unit, which means it provides a constant connection and cools effortlessly. There are different types of thermal paste available in the market- you’ll see silicon-based compound, metal-based compound, carbon compound, ceramic-based compounds. Among these types, for most applications, a metal-based compound is used because it provides excellent thermal conductivity. Thermal paste flows continuously as a liquid, the maximum temperature limit is 150 degrees C whereas some paste can withstand up to 300 degrees C.
