9 Best Thermal Pastes for CPU, GPU in 2022

Selecting the best thermal pastes for CPU may appear straightforward, but the dizzying amount of alternatives may quickly transform this fairly simple chore into a time-consuming one. Thermal paste is used to fill small air gaps and imperfections between the cooler’s surface and the CPU’s IHS (integrated heat spreader), the metal component built into the processor’s top.

A good thermal paste may significantly improve your performance by allowing your CPU to transmit more of its waste heat to your cooler, which keeps your processor cool.

Choosing the best thermal pastes for the CPU is particularly critical if you intend to fully overclock your machine. Even the greatest gaming CPUs can frequently achieve significantly higher overclocks when combined with a decent thermal paste.

You do not have to worry about all of these things because we have researched some of the best thermal pastes for CPU which we will bring in the article. Keep on reading but before that check how a thermal paste for CPU works so you can choose the one according to your preferences.

What is a Thermal Paste? & How Does It Work?

Thermal paste is a heat conductive compound that is sandwiched between a heat sink and the equipment being cooled. It may also be used with other components, most notably a CPU and an ac cooler.

Thermal paste aids in improving heat conduction. Heatsinks, CPUs, and coolers contain minute, unnoticeable defects that can trap air and reduce the heat sink’s overall performance.

Thermal paste smooths out these surfaces and maximize their efficiency. Air is inefficient in conducting heat, and the heat sink is designed to do just that. Heat conduction is the process through which heat is removed from the component that generates it.

The Best Thermal Pastes for CPU

So now you know what is a thermal paste and how does it work. Let’s check out the list of the best thermal pastes for CPU and GPU on the market.

We covered all forms of best thermal pastes, including those made of metal, ceramic/diamond, carbon, and liquid metal. You can choose what matches your taste and your budget.

4. Cooler Master MasterGel Maker

Cooler Master never ceases to amaze us with its innovative products and this is a great contender in our list of best thermal pasters for CPU. The gel Maker thermal paste is one of their live and breathing goods. Compared to other flagship goods in the same category, Cooler master thermal paste is head and shoulders above the competition.

It utilizes nanodiamond carbon particles, which are lighter than their predecessors (micro carbon particles), making it less weighable. When the electrically conductive phase of the Master gel is considered, it is almost minimal.

Features at a glance

  • It has 11 W/mK thermal conductivity and best in the class product.
  • Also, this best thermal paste for CPU gets the extraordinary viscosity and an electrical insulator.
  • A great needle design ensures a uniform and precise spread of the material.
