Is Corsair Thermal Paste Good?

After testing the Corsair thermal paste and comparing it with other rivals, I can conclude that Corsair thermal pastes are well-suited for overclocking activities, as they offer low thermal resistance and excellent thermal conductivity to help dissipate heat efficiently. If you’re building a new PC or upgrading your cooling system, Corsair thermal paste is worth considering.

When changing processors, I never use the factory paste. I always buy a tube of the good stuff. So my first encounter with the Corsair thermal paste (TM30 version) was when I was installing a new processor for my overclocked Ryzen 7 5800X and MSI 240mm AIO.

In this article, I will share my findings about using Corsair thermal pastes, in general, to determine if they are worth your investment. But we will particularly focus on the TM30 product, which is a popular choice.

Types of Corsair thermal pastes

Many new builders often overlook thermal paste when putting together a PC. Indeed, CPU coolers these days come with thermal paste pre-applied, but if you invest in a good thermal paste, you won’t be lagging when you need to reseat the CPU or the cooler after cleaning the old coating.

When it comes to investing in a good thermal paste, Corsair is a popular name in the industry. But there are also other options. The most popular types of Corsair thermal paste available on the market right now are:

Corsair TM30 Performance Thermal Paste

This high-performance thermal paste offers low thermal resistance and excellent thermal conductivity. It is easy to apply and can be used with various CPUs and GPUs. This is a very popular options and for good reasons.

Corsair XC7 RGB Thermal Paste

This premium thermal paste is designed specifically for Corsair’s XC7 RGB CPU water block. It features a high-viscosity formula that provides excellent heat transfer and is compatible with various CPUs.

Corsair XTM50 High-Performance Thermal Paste

This high-performance thermal paste provides maximum heat transfer between a CPU or GPU and its heatsink. It features a low-viscosity formula that makes it easy to apply and is also

non-conductive, ensuring that it won’t damage your components.

Corsair CT-9010002-WW TM5 High-Performance Thermal Compound

This high-performance thermal paste is designed to provide excellent thermal conductivity and low thermal resistance. It is easy to apply and is compatible with a wide range of CPUs and GPUs.

Corsair TM50 Performance Thermal Paste

This high-performance thermal paste is designed to provide excellent thermal conductivity and low thermal resistance. It is easy to apply and is compatible with a wide range of CPUs and GPUs.

Let me also reiterate here that different types of thermal paste can have varying levels of effectiveness depending on your specific cooling setup and the components you’re using.

The TM30 version is a favorite choice among gamers; chances are this is the product you’ve looked into to meet your needs. Now, let’s drill down into my review of this product.

My Corsair Thermal Paste Review

To begin with, the Corsair TM30 thermal paste compound is similar to most thermal compounds available on the market. So if you are investing in this product (even with the slightly higher price), don’t expect to get a groundbreaking temperature performance difference.

My Favorite Corsair Thermal Paste

With that out of the way, let’s look at the various review factors


Corsair thermal pastes have impressive packaging. Many of their products are designed for the syringe, which also acts as the applicator. For example, the TM30

However, the product is only offered in the 3G model, but in my case, it was sufficient for 10 to 15 purposes on mainstream processors from Intel LGA 115X or AMD AM4 sockets.


According to the information on the Corsair website, the thermal paste compound has a thermal conductivity rating of 3.8 W/mK.

The compound is a zinc-oxide-based mixture that is non-conductive, non-volatile, and non-toxic. Corsair is also famous for its low viscosity, which helps fill the microscopic gaps between the CPU and heatsink.

So even when I jaded the applicator that came with the packaging and used the “dot” application pattern for the paste, it applied well.

Temps Performance

To get a clearer idea of how this brand of thermal paste measures up, I ran the test on multiple platforms, with Intel and AMD processors in a Windows 10 device with high load and ideal.

The Corsair TM30 thermal paste performs moderately, thanks to the extra liquid combination that hints at its extended lifespan without any crack or dry issues.

However, on temperature performance, I’d say that you should go with the ThermalTake One product if you have the option to get better thermal paste for the same price as the Corsair because it performs 3-5 degrees Celsius better and 11 points better on Cinebench.

Also, a few other thermal paste options come with a lot more paste in the box and applicator, so you won’t miss out on these perks if you choose not to go with the Corsair.

Pros and Cons of Choosing Corsair thermal paste

Corsair thermal paste is a popular choice for those looking to improve the cooling performance of their CPU or GPU. But still, it has its advantages and disadvantages. So while it may be the best option for you, keep these factors in mind:


  • Good thermal conductivity
  • Easy to apply
  • Non-conductive
  • Compatibility with a wide range of CPUs and GPUs
  • Long-lasting


  • Higher price compared to some other thermal pastes
  • Availability may be limited in some regions
  • Performance may vary depending on your specific setup

Final verdict

The bottom line, really, is that there’s not always a massive difference between high-rated thermal pastes on the market these days, especially if you’re an average PC builder.

Still, each brand or product has a unique selling point. For Corsair, thermal paste, they seem to be the best option for easy application. For example, the Corsair XTM50 comes with an application stencil and spreader.

Hence, I would strongly recommend Corsair for first-time builders since they won’t have to worry about spilling the paste on the CPU socket or other surrounding components.

Meanwhile, the tube of Corsair thermal paste looks small (compared to many other options). Still, they usually provide more than enough to do the job for a new PC build, and, as in my case, there is even plenty left over to refresh older systems if needed.

Our PC builds and gaming needs will differ, so time will tell how well any thermal paste will hold up for you.

However, you can invest in a Corsair thermal paste today with the confidence that you didn’t make the wrong decision.
