Now that you know about the CPU stress testing tools, let’s take a deeper dive into CPU stress testing itself and how it can help your PC.
Why Do You Need CPU Stress Testing?
Let’s look at some of the reasons why you need stress testing.
- Performance issues in old computers: If you find your laptop crashing down even for small tasks, performing very slowly that kills your time, or shuts down abruptly for no reason, consider CPU stress testing. It will help you determine the cause behind the issue so you can fix it before any permanent damage happens to your computer.
- Overclocking: If you use your computer rigorously for official work, gaming, designing, or anything else that requires high CPU performance, you may consider overclocking. It is the process of making the CPU run at a higher speed than initially intended. CPU stress testing can help to check if its performance has increased after overclocking.
- To determine a computer’s maximum performance: You do not always get the performance mentioned on the box or as promised by the salesperson. Your computer is a machine with plenty of components to affect performance and stability. CPU stress testing lets you judge the realistic performance you can expect from it. It will also help you figure out whether the machine is working well and determine the thermal paste and cooling system performance.
Furthermore, monitoring the CPU during stress testing is essential. It will measure the PC temperature, voltage fluctuations, clock speed, etc., to ensure everything is well with your device. And if anything goes wrong, you can take remedies quickly to fix it before an issue damages your computer. Also, PC benchmark testing too is recommended, so you should try some of the best PC benchmark software for a safe and effective experience.
Many have double doubts regarding the safety of CPU stress testing tools. Remember that CPU stress testing is safe if done correctly. Under a given load, a CPU generally reaches a maximum temperature in an hour. And when it reaches a critical limit, the computer shuts down automatically to prevent any damage.
Finally, let’s see how you can perform a CPU stress test by yourself.
How To Perform CPU Stress Testing With Care?
As explained above, care must be taken while performing CPU stress testing to ensure everything goes well and you can get the optimum results. For this, you must also prepare your system before starting the test.
- Close unnecessary applications: Before performing CPU testing, close other applications running on your computer, as they may interfere with the testing process. This also enables the CPU stress testing tool to utilize the full CPU.
- Keep an eye on the temperature: As the complete stress is on the CPU, you must observe its performance closely. Check its temperature to understand its temperature threshold. If it goes beyond 90 degrees Celsius, you must not perform the test for a prolonged period.
- Ensure the CPU reaches its full usage: CPU stress testing is done to ensure your CPU works at its maximum capacity, not just to test its performance. Hence, allow it to work at its 100% capacity.
- Look for the CPU’s overclocking settings: Find out whether overclocking your CPU is safe or not. Many CPUs allow easy overclocking, like the Intel K series, while others may give a hard time to you.
With this, you should have enough information to try a CPU stress test at home without any issues.
