10 Best CPU Stress Test Software for Windows PC in 2022

Computer performance often gets degraded with time, and you’ll notice various issues coming up with time. On top of that, if you are using your system daily, the chances of issues hitting early also rise. With time, you will see unexpected shutdowns, different functions not working as they are supposed to, and frequent slowdowns in different phases.

These are indications that you should never ignore. If these issues prevail for a long time, your system might even have to suffer permanent damage.

So, how can you avoid getting into such conditions?

You need to monitor your computer’s health and performance by conducting CPU stress testing with the help of CPU stress test software. This will make you aware of everything about your PC and help you maintain your computer’s health.

Before we get to the list of the best CPU stress test software, let us briefly discuss what stress testing software is.

What is CPU Stress Test Software?

CPU Stress testing is a type of performance testing of the CPU under high-stress levels. This helps in evaluating the system’s abilities even under extremely rigorous conditions. With CPU test software, you will be able to discover how much stress all your CPU components can endure before they get damaged.

The stress test performed by PC stress test software includes various extreme tasks, memory usage at intense levels, testing clock speeds, and providing extreme workload.

CPU stress testing is a part of hardware stress testing that checks for the CPU’s performance when it runs at maximum levels and temperatures. During this testing phase, every core of your CPU will be utilized and tested to see the levels it can handle.

If your CPU can pass the stress test performed by computer stress test software, it is considered to be stable. If your system can’t sustain the stress tests, you will experience crashes, lag, and automatic shutdowns that indicate instability. With stress testing, you’ll know if your system needs fixing.

Why do you need CPU stress testing?

CPU stress testing is really important to discover your system’s health and verify its stability. The three main reasons for performing stress testing are:

  • Performance issues in old systems – If you notice that your old system is lagging and working very slowly, you should perform a CPU stress test to see how you can fix the system.
  • Overclocking – If you’re using your system under extreme conditions for work or gaming, you would demand more speed. With stress testing, you can find out whether your system’s performance has been enhanced with overclocking or not.
  • Explore maximum performance – Stress testing can help you determine whether your system is working at a maximum performance or you need to fix the components. This will prevent any issues of permanent damage to your system.

What should I use to stress test my CPU?

For performing adequate CPU stress testing, you need to choose the best PCU stress test software. The right tool will help you rigorously test your system under extreme conditions by imparting maximum load. With real-time monitoring, you will know which component needs fixing and how you can enhance your system’s performance.

How long should you run a CPU stress test?

This will depend a lot on your system and its configurations, but on average, you should stress test your CPU for at least one hour. This much time is enough for your CPU to reach its maximum temperature. At this time, you can impart maximum load on your system. But, if you wish to check the stability and reliability of your system, you can perform a prolonged stress test even for 24 hours. This is a long time for any system. You should perform such a prolonged test only if there are plenty of issues with your system.

Are PC stress tests safe?

If you are using a professional PC stress test software, there is no need to worry about your system. Every CPU has certain threshold limits for the system, and the system will automatically shut down before any damage can be done. If your system is too old and you try to perform prolonged stress testing, there are slight chances of your CPU getting damaged. The chances of such a scenario are pretty rare.


This was the list of the best computer stress test software that you can check out if you are more concerned about your system’s health and performance. With these tools, you will be able to enhance your device’s reliability and stability by fixing it before time.
