Best Thermal Paste for CPU to Buy in 2022

Best Thermal Paste for CPU to Buy in 2022

Every PC enthusiast strives to maintain the processor temperatures of their machine as low as possible. This is essential and necessary since, in order to prolong their lifespan, neither the CPU nor the GPU should operate at excessive temperatures. The stock CPU coolers that come with the majority of the CPUs on the market right now are typically poor quality and do not provide the optimum cooling performance. Here comes the importance of thermal paste for the CPU.

If you’re not familiar with the term, a thermal paste is simply a thermally conductive substance that is typically put between the processor (CPU or GPU) and the cooler’s heatsink to prevent air gaps and enhance heat transfer between the IC and the cooler.

So, we strongly advise you to buy a high-grade thermal paste if you’re an enthusiast who wants the very highest “thermal performance” out of your CPU and GPU. There are many of these on the market, so if you’re not sure which one to choose, listed below are the top ten thermal pastes for CPU and GPU.

What Are Thermal Pastes?

Thermal pastes, as already established, are chemical substances, frequently viscous or gelatinous, that help thermal conductivity between an IC and its heat sink. They are also known as a thermal compound, thermal grease, thermal gel, etc. They accomplish this by removing air gaps from the cooler’s interface with the CPU or GPU, which reduces thermal insulation and increases heat dissipation. They are often electrically insulating but are always thermally conducting.

How to Choose a Thermal Paste

While searching on the internet you can find hundreds of thermal pastes enlisted on various eCommerce sites. But, how to find the right one? Look for the features enlisted here: 

1. Composition:

In essence, this will have one of two effects on your transaction. If the substance has a metallic foundation, as was previously noted, it must be treated with extreme caution to prevent getting on the circuits. It can corrode your circuit boards in addition to it being electrically conductive, which effectively bricks your pricey gaming motherboard.

The majority of liquid metal thermal pastes will degrade aluminum and have a very severe reaction if you have an aluminum CPU cooler heatsink. Choose something non-corrosive or utilize a copper heatsink that has been nickel-plated.

2. Thermal Cycles

Some products need to go through a few temperature cycles in order to perform properly. This implies that they need to be exposed to significant temperature fluctuations in order to colonize every crevice. The compound will require more thermal cycles to properly activate the greater the viscosity.

3. Specifications

There are a few aspects to think about while purchasing thermal paste. The paste will be more conductive the higher the heat transfer values. Therefore, 38 W/mk pastes will be more conductive than 12.5 W/mk (12.5 Watts per meter Kelvin) pastes. Nevertheless, since your results will vary depending on your cooling system’s components, any thermal paste from a respected manufacturer will work just fine. In practice, you’ll only notice a small amount of -/+ from your old thermal paste.

4. Grammage

If you use 1.5-gram syringes on common LGA 1151 or AM4 chips, they can be used about three to four times. You’ll need to purchase 3.5-gram or bigger syringes for LGA 2066 or Threadripper CPUs in order to completely cover the chip.

  3. Non-Corrosive
  4. Not Electrically Conductive

Price: $10

Pros:

  1. Excellent Heat Conductivity and Easy To Apply
  2. Non-Conductive

Cons:

  1. Not quite as adhesive as claimed

Buy Now: Antec Formula X Thermal Paste

Features: An amazing thermal compound with good cooling capabilities at a reasonable price is the Antec Formula X Thermal Paste. It comes in a 3.5-gram syringe that may apply the material to a CPU heat spreader several times. The paste has a thermal conductivity of 11 w/mk, which is average but sufficient for the majority of users who aren’t hardcore overclockers.

The substance has been designed to be durable and to have long-term cooling stability. It is also non-corrosive and electrically non-conductive. Don’t use the paste as an adhesive, despite the manufacturer’s claims that it is highly sticky. A plastic spatula for spreading the paste, the aforementioned syringe with the paste, and a few wipes for wiping out the contact surfaces are all included in the package. Overall, this is a fine thermal paste for most people, but if you want to push your CPU to its OC and beyond boundaries, a liquid metal thermal compound is probably a better option.

3. Thermal Grizzly Kryonaut

Best Thermal Paste for CPU_3

Specifications

  1. Made for air and water cooling
  2. Compatible with sub-zero overclocking
  3. Non-corrosive, can work with aluminum coolers

Buy Now: Thermal Grizzly Kryonaut 

Features: The Thermal Grizzly Kryonaut thermal compound was excellent in our opinion. The fact that it’s designed for overclockers is a major plus. For the best results, we advise you to place the tube in a ziplock bag and soak it in warm water for a few minutes before applying it to your selected surface because the viscosity of the product relies on the temperature it has been kept in.

If you apply it using the previously indicated way, everything will go smoothly. A thermal application tool, which is really helpful if you’re trying to apply it in an even coating, is included with the one-gram tube. It lasts a long time and is the ideal paste to replace your dried-out, grit-filled compound. The Thermal Grizzly Kryonaut thermal paste transmits heat efficiently enough to be an enthusiast-grade product even though 12.5 W / mk doesn’t appear excessive. Perfect all-around, great if you’re interested in overclocking and searching for a new thermal compound.

Price: $9.99

Pros:

  1. Best for novices
  2. Produces positive outcomes
  3. Long-lasting

Cons:

  1. Less heat conductivity than rival products
  2. Unfavorable to overclockers

Buy Now: CORSAIR XTM50

Features: It’s challenging to think of a region of the PC community where Corsair is completely absent. The XTM50 is a low-viscosity liquid thermal compound that claims to increase the lifetime in that regard. The chance of damage increases every time you disassemble your computer, so using a long-lasting paste is a wonderful approach to reduce this kind of interaction.

It is one of the best pastes for application because of its low viscosity. However, because it is less conductive in the liquid state, you won’t get as good of results as you would with a product like Cooler Master, Arctic, or Thermal Grizzly. Overall, it’s fantastic if you’ve never used thermal paste because it still produces trustworthy results. Simply put, high-end overclocking isn’t its intended use.
