When it comes to squeezing every last bit of performance out of your gaming rig, enthusiasts often turn to overclocking, upgrading their graphics cards, or tweaking their system’s cooling setup. One common question that arises in this pursuit of maxed-out frames per second (FPS) is: does changing thermal paste really make a difference? Can something as seemingly simple as applying a new layer of gooey paste between your CPU and cooler really give you a noticeable boost in gaming performance?
The Basics of Thermal Paste
Before we dive into the meat of the matter, it’s essential to understand what thermal paste is and how it works. Thermal paste, also known as thermal interface material (TIM), is a substance applied between a heat source (in this case, your CPU) and a heat sink (your CPU cooler). Its primary purpose is to fill microscopic gaps between the two surfaces, creating a more efficient heat pathway and allowing heat to dissipate more effectively.
There are various types of thermal paste available, each with its own set of characteristics, advantages, and disadvantages. The most common types include:
- Ceramic-based pastes: These are relatively inexpensive and offer decent thermal conductivity.
- Metal-based pastes: These often contain metals like silver or copper, which provide excellent thermal conductivity but can be more expensive.
- Carbon-based pastes: These are typically used in high-performance applications due to their exceptional thermal conductivity and durability.
The Importance of Proper Application
Applying thermal paste correctly is crucial to its effectiveness. A sloppy or uneven application can lead to reduced thermal conductivity, which negates the benefits of using a high-quality paste. Here are some key takeaways for proper application:
- Ensure the surfaces are clean and free of debris
- Apply a small amount of paste (about the size of a grain of rice) to the center of the CPU die
- Use a credit card or similar tool to spread the paste evenly across the surface
- Verify the paste is evenly distributed and free of air pockets
The Impact of Thermal Paste on FPS
Now that we’ve covered the basics, let’s get to the heart of the matter: can changing thermal paste really improve your FPS? The short answer is: it depends.
In general, a high-quality thermal paste can provide a minor boost to your system’s overall cooling performance, which can, in turn, lead to increased FPS. However, the extent of this improvement depends on several factors:
- The quality of the original thermal paste: If the original paste was subpar, switching to a high-quality alternative can result in a noticeable difference.
- The system’s cooling capabilities: If your system is already well-cooled, the impact of a new thermal paste may be less pronounced.
- The CPU’s temperature: If your CPU is running at extremely high temperatures, a better thermal paste can help reduce temperatures and increase FPS.
To illustrate this, let’s consider a hypothetical scenario:
Suppose you’re running a mid-range gaming PC with a stock CPU cooler and a decent graphics card. You’re getting an average FPS of 60 in your favorite game. After applying a high-quality thermal paste, you notice a 5-7°C reduction in CPU temperatures. This, in turn, allows you to increase your CPU clock speed by 100-200 MHz, resulting in a 5-10% increase in FPS.
Real-World Examples and Benchmarks
To put this into perspective, let’s look at some real-world examples and benchmarks:
- A study by Tom’s Hardware found that switching from a stock thermal paste to a high-end paste resulted in a 10-15°C reduction in CPU temperatures, leading to a 2-3% increase in FPS in gaming benchmarks.
- A review by TechPowerUp found that a top-tier thermal paste reduced CPU temperatures by up to 12°C, resulting in a 4-6% increase in FPS in demanding games like Assassin’s Creed Odyssey.
- In a benchmarking test by Overclockers.net, a high-quality thermal paste resulted in a 5-7°C reduction in CPU temperatures, leading to a 1-2% increase in FPS in games like Fortnite and PUBG.
While these results may not be earth-shattering, they do demonstrate that a high-quality thermal paste can have a tangible impact on your system’s performance.
Other Factors That Affect FPS
It’s essential to remember that thermal paste is just one piece of the puzzle when it comes to achieving maximum FPS. Other factors that can significantly impact your gaming performance include:
- CPU and GPU clock speeds: Overclocking your CPU and GPU can result in significant FPS gains.
- RAM and storage: Insufficient RAM or slow storage can bottleneck your system, reducing FPS.
- Cooling system efficiency: A well-designed cooling system, including fans, radiators, and airflow, can keep your components at optimal temperatures.
- Graphics settings and optimization: Tweaking graphics settings, such as resolution, detail, and rendering, can greatly impact FPS.
- Driver updates and patches: Keeping your graphics drivers and game patches up-to-date can often resolve performance issues and improve FPS.
Conclusion
In conclusion, changing thermal paste can indeed have a positive impact on your FPS, but it’s essential to understand the underlying factors that affect your system’s performance. By applying a high-quality thermal paste correctly, you can potentially squeeze out a few extra frames per second, especially in demanding games. However, it’s crucial to consider the bigger picture and address other areas that may be bottlenecking your system.
Remember, every system is unique, and the impact of thermal paste on FPS will vary depending on your specific setup. Experiment, benchmark, and optimize – and you may be surprised at the performance gains you can achieve.

What is thermal paste, and why is it important for my computer?
Thermal paste, also known as thermal interface material (TIM), is a substance applied between the CPU die (the top surface of the processor) and the heat sink or CPU cooler to improve heat transfer. It fills in the microscopic gaps between the two surfaces, allowing heat to be dissipated more efficiently. This is crucial because excess heat can throttle your CPU, reducing its performance and potentially causing damage.
A good thermal paste can make a significant difference in keeping your CPU at a safe temperature, especially during intense gaming sessions or heavy workload operations. With a high-quality thermal paste, you can expect improved system performance, reduced noise levels, and increased overall system reliability. In the context of gaming, a well-cooled CPU can result in higher frame rates, faster loading times, and a more enjoyable gaming experience.
Can changing thermal paste really boost my FPS?
Yes, changing thermal paste can potentially boost your FPS (frames per second) in certain scenarios. If your system is overheating, a high-quality thermal paste can help reduce temperatures, which in turn can increase your FPS. This is especially true for systems with high-performance CPUs or those running demanding games. By keeping your CPU at a lower temperature, you can maintain higher clock speeds, resulting in improved gaming performance.
However, it’s essential to note that the impact of thermal paste on FPS is highly dependent on the system’s specific conditions. If your system is not overheating, changing thermal paste may not result in a significant FPS boost. Additionally, other factors like GPU performance, RAM, and storage also play a crucial role in determining your FPS. So, while thermal paste can be a contributing factor, it’s not the only variable at play.
How often should I replace my thermal paste?
The frequency of replacing thermal paste depends on various factors, including the quality of the original paste, the operating conditions of your system, and the type of CPU cooler used. Typically, high-quality thermal paste can last for 3 to 5 years or more, depending on the manufacturer’s recommendations. However, if you notice a significant increase in temperatures or a decrease in system performance, it may be a good idea to replace the thermal paste earlier.
Additionally, if you’re upgrading your CPU or replacing your CPU cooler, it’s a good idea to apply new thermal paste to ensure optimal heat transfer. In some cases, especially with older systems, the thermal paste may dry out or degrade over time, leading to reduced performance. Replacing it with a fresh application can help restore your system to its original performance levels.
What’s the difference between ceramic, metal, and carbon-based thermal pastes?
The main difference between ceramic, metal, and carbon-based thermal pastes lies in their composition, thermal conductivity, and performance characteristics. Ceramic-based thermal pastes are electrically non-conductive and typically have a lower thermal conductivity than metal-based pastes. They’re suitable for most systems and offer a good balance between performance and cost.
Metal-based thermal pastes, on the other hand, have higher thermal conductivity and are often used in high-performance systems. They can be electrically conductive, so it’s essential to handle them carefully to avoid damaging your components. Carbon-based thermal pastes are a newer type of TIM that offers high thermal conductivity, low thermal resistance, and excellent performance. They’re often used in high-end gaming systems and overclocking applications.
Can I apply too much thermal paste?
Yes, applying too much thermal paste can be detrimental to your system’s performance. Excess thermal paste can create a barrier between the CPU die and the heat sink, reducing heat transfer efficiency. This can lead to increased temperatures, reduced system performance, and potentially even damage to your components.
When applying thermal paste, it’s essential to use the correct amount, as specified by the manufacturer’s instructions. A general rule of thumb is to apply a small pea-sized amount or a thin, even layer to the CPU die. This ensures optimal heat transfer while minimizing the risk of excess paste interfering with the cooling process.
What’s the best way to apply thermal paste?
The best way to apply thermal paste is to follow the manufacturer’s instructions, which may vary depending on the specific product. Generally, it’s recommended to apply a small amount of paste to the center of the CPU die, then spread it evenly using a credit card, scraper, or applicator tool. This helps to create a uniform, thin layer that covers the entire surface.
When applying thermal paste, make sure your CPU and heat sink are clean and free of debris. Use gloves or a plastic applicator to avoid contaminating the surface with oils from your skin. Apply the paste in a well-ventilated area, and avoid inhaling the fumes. After application, ensure the heat sink is securely fastened to the CPU to ensure optimal contact and heat transfer.
Can I reuse thermal paste from an old CPU cooler?
It’s not recommended to reuse thermal paste from an old CPU cooler. Thermal paste is a single-use product, and reusing it can compromise its performance and effectiveness. The paste may have dried out, degraded, or become contaminated during its previous use, which can lead to reduced heat transfer efficiency and increased temperatures.
Additionally, thermal paste is designed to be used in a specific application, and reusing it may not ensure optimal performance in your new system. It’s best to purchase a new tube of thermal paste specifically designed for your new CPU cooler or system configuration. This guarantees optimal heat transfer and performance, ensuring your system runs at its best.
