But before we move further, you need to know about what actually is a thermal paste and how you can apply a thermal paste in the best possible way to keep the temperature of your GPU or CPU moderate or cool.

A thermal paste is defined as,

“It is a thermal compound which is used for the purpose of heat conduction between two surfaces and these two surfaces are most commonly a microprocessor and a heat sink.”

Thermal paste is used to lower down the temperature of the CPU or GPU by several degrees, which can vary from hardware to hardware. In order to maintain the proper functions of your PC. Just like the ethernet cable, it’s a product that is often overlooked while building a new gaming rig.

Different Types of Thermal Paste

There are four common types of thermal paste that you should know of.
These are discussed briefly below.
  • Metal Thermal Paste: Metal thermal pastes are the most effective pastes, and they can reduce the temperature by about 10 degrees. It is also capacitive, so be cautious! You need to apply this type of paste carefully and avoid spilling it on metal parts of the motherboard to prevent short circuit. Do not use liquid metal on aluminum heatsinks as the metal can cause damage to it.
  • Ceramic thermal paste: Ceramic thermal paste doesn’t contain any type of metal, and hence they are easier to use as you don’t have to worry about spilling it on metal parts of the motherboard. However, they are cheaper than metal paste which is excellent for the consumer, but they usually don’t provide the same temperatures drop as metal.
  • Carbon Thermal Paste: Carbon thermal paste is up for discussion regarding it provides a better result than liquid metal pastes. The idea behind carbon-based paste is that it offers the best of two worlds, it’s none electrically conductive and yet provides a superior temperature drop than metal paste. However, in our review, we find it to work just as good as metal-based. There are also hybrid-compound solutions that offer different micro-particles that stand out in a similar manner, for example, Noctua NT-H1.
  • Silicon Thermal Paste: Not a single silicon thermal paste made it to this list; it simply didn’t keep up with the rest of the thermal compounds we reviewed. Silicon thermal paste was pretty much standard for a long time, until the new innovative, high-end thermal pastes entered the market.

Apply the Thermal Paste Correctly

There are many specific ways to apply the thermal paste on the surfaces for getting better results. Let’s take a look at some of the most common methods used one by one.

  • The Vertical Line Method: In this method, people tend to apply a vertical line on the surface of the CPU resulting in the line spreading out while the processor is pressed on. This created a more even coating of the paste than if you would apply it by smearing it out. Resulting in it a more cooled down temperature because of the excellent contact surface.
  • The X Method: Like the vertical method, just that you apply two lines in an X before pressing down the CPU. However, be careful of not applying to much paste, it will leak on your motherboard otherwise. And if using a metal-based paste, it can cause severe damage. By this method you will also waste more paste as the difference in performance from the one line method is none. 
  • The Pea Method: This is probably the best method of them all; you will save on your paste and get a very even surface of thermal paste. It’s the most effective either way. You just apply a small dot in the middle, big as a pea and press down the processor. The paste will spread as you put the pressure on the heat sink or CPU. 

Other than these methods, some thermal pastes also come up with tools like sticks etc. Which is used to spread the paste on the surface. However, we would still recommend to apply it with one of the methods mentioned above. Well, this was a little bit knowledge about thermal pastes and how to apply them.

Conclusion

Well, after a lengthy review, we are now sure that you can make a confident choice depending upon the needs and your system requirements. Make sure to choose the one which works for a more extended period and has a reasonable price range for you. It’s important to note that if the thermal paste is not applied correctly, it doesn’t matter how good thermal compound you have. If the contact with the heatsink is terrible, the temperature will not transfer effectively.

We hope you enjoyed this guide and found the information you where looking for the best thermal paste. If you want our recommendation, we will recommend you to have a look at the Arctic Silver 5, ARCTIC MX-4 or Noctua NT-H1 as they impressed us the most. If you want a thermal pad, Innovation Thermal Pad is the suitable choice for you. Good luck!
