Does an Overheating CPU Affect FPS in Game? 2024

Before heading deeper into the topic, one should know what FPS is and how it affects in-game performance. It is actually abbreviated as frames per second which means how many images are being shown on the screen in one second. A 30 fps means thirty images in one second, but this is not recommended since it’s not that smooth. A higher FPS will make the experience considerably smoother, which is its most obvious advantage. You will observe a high frame rate in smoother animations, especially in games with lots of action. 

On the other hand, a processor or CPU is one of the most important components of a computer since it supervises the overall performance of the system. It handles every in and outs by acting as a brain for PC. But there are several factors that may affect it overall efficiency, and temperature could be one of them. Therefore, we will look at does an overheating CPU affect fps in game plus cover a lot of other factor to further simplify the query. You must read this post until the end to absorb every bit of information. 

Key Takeaways

  • The CPU is the central processing unit of the computer, which performs calculations and instructions for various programs and processes, including games.
  • The CPU can overheat when it is under heavy load, such as when playing a demanding game, or when it is poorly cooled, such as when the fan or heatsink is dirty or damaged.
  • The CPU can affect the FPS, which is the number of frames per second that the game displays on the screen, depending on the game’s optimization and demand.
  • The CPU can cause FPS drops when it overheats, because it will throttle down its speed and performance to prevent damage and reduce heat generation.
  • The CPU can also cause FPS stuttering when it overheats, because it will fluctuate between high and low speeds and performance, resulting in inconsistent frame rates.

Does an Overheating CPU affect FPS in game?

A temperature issue that results in the CPU overheating is a poor indicator because it could lead to the processor’s failure and instability in the system’s hardware. Game shutdowns crashes, and performance difficulties like low FPS can be brought on by overheating hardware. So answer to does an overheated processor affect the frames-per-second rate is yes. It does affect FPS in the game, as high FPS is essential in competitive games to play smoothly and optimally.

How to detect an overheating CPU?

There are several indications by which you can detect that your CPU is overheating. Some of them are given as follows.

  • Sudden and repetitive shutdowns and restarts indicate the overheating of the CPU
  • The high sound of fans is also a massive indication of overheating of the CPU as due to overheating, fans are excessively used
  • Lagging of the system is another indicator of the heating processor

What are some common reasons for CPU overheating?

Some most common reasons for CPU heating are given as follows: 

The poor cooling system of the PC: CPU temperature may increase significantly if your system has a poor CPU cooling system, such as damaged or malfunctioning fans. This can be rectified by using a proper ventilation system. Keep all the ventilation spaces open

Increased workload on PC: Heavy workloads will increase the CPU’s temperature. If the CPU must operate at maximum frequency for a long time when doing demanding activities, then it becomes highly heated as a result, so you should always work according to the processing capacity of the CPU.

Overclocking of PC: Overclocking can even damage your CPU if you don’t use an excellent cooling system. For this problem, you can apply a good thermal paste, or for laptop users, you can use a cooling pad for thermal stability.

Presence of any virus: Malware or viruses can affect CPU temperature, which causes the processor to overheat. This issue can be resolved by installing antivirus software.

Having outdated software: Out-of-date software can occasionally cause problems for the system. The processor overheats as it attempts to solve the problem. This can be solved by updating software regularly.

How does an overheated CPU affect FPS in game?

Overheating of the CPU significantly affects the FPS as low FPS in gaming makes it worth less, so a reasonable frame rate is necessary. Skilled players can only play at 144 frames per second or above. Frame rates can be severely decreased by high CPU temperature. Dust, heat, and cold can affect your CPU performance. The most prominent of these is overheating. A CPU automatically lowers its rate when it gets too hot. Your game will appear inaccessible as a result. 

Some factors that can reduce FPS

Here are some other factors that can reduce FPS other than overheating;

  • Modern games cannot be played at high frame rates on outdated hardware.
  • Outdated GPU drivers can lower the frame rates of games.
  • Frame rates can be dramatically impacted by slower RAM.
  • In-game options can adjust frame rates. High settings always result in low frame rates.
  • Lower frame rates in games are caused by single-channel RAM, which prevents your CPU from operating as it should.
  • Enabling motion blur and depth of field in video games may cause frame rates to drop.


Overheating of the CPU significantly affects FPS as games run at reduced frame rates when the CPU is heated. As you already know, the CPU is the main component of a computer as it is considered the soul of a computer. A computer can not operate entirely without a CPU, so proper conditioning of the CPU is necessary for the optimal functioning of the PC. Therefore, be cautious about maintaining an excellent CPU. An adequately cooled CPU can improve system performance and game frame rates. FPS is essential in keeping the gaming experience. 

Overheating due to dust, viruses, or outdated software can be rectified by taking proper measures. In the article given above, all your queries regarding CPU overheating and its effect on FPS are described in detail, so the main question of whether an overheating CPU affects the FPS in the game is elaborated. Suppose you are a professional gamer and you assume that your CPU has started to overheat. In that case, you must try the methods given above to cool down your CPU for the best gaming experience.
