Things to Know Before Stress Testing
Before you begin stress testing your CPU, you need to make sure of a couple of things.
- Since the stress testing would be done through a browser, close all other non-essential and background processes. It’s because you want your PC to be free from any external load and the full processing capability focused during the stress test.
- Make sure that you have disabled any screen-saver and sleep mode before starting the test.
- Stress testing your PC can push its components to perform at their peak, significantly driving up the heat released. There is a safeguard that comes with most PC components today, whereby they shut down automatically if the temperature gets too high.
- Download HWMonitor to keep a check on the heat. The general rule is that CPU temp should not exceed 70 degrees Celsius and GPU temp should not exceed 100 degrees Celsius. If the components exceed this limit, stop the stress test immediately. Also, it’s better to perform the stress test in an air-conditioned room.
Let’s look at some free CPU stress testing tools with that taken care of.
12 CPU Stress Test Software to Use in 2023
