In the System Stability Test, you can choose which component (CPU, memory, local disks, GPU, etc.) you want to stress. This is excellent for gauging workstations or servers that are meant for sustained, high-performance workloads.ĪIDA64 is an all-in-one diagnostic tool that can be used to look at details of your particular system. Instead of purely stressing the CPU like Prime95, it simulates a more realistic workload that a CPU is likely to have.

This tool is geared more toward engineers, IT professionals, and enthusiasts (as indicated by the various download options). The cheapest version is AIDA64 Extreme, which will run you about $50 for three PCs while the Business and Engineer versions go for $200. Unlike the other tools on our list, AIDA64 is not free to use. A word of caution with Prime95: It has a somewhat negative reputation of putting unnecessary stress on the CPU. The large FFTs really punish your CPU, while the blended tests push RAM usage. The small fast fourier transforms (FFTs) can be a good way to see if there are any issues. You can run different “torture tests” depending on what you’re trying to stress. Though Prime95 is not originally made to stress test the CPU, the strain in using the processor’s floating point and integer capabilities make it an excellent way to see what your CPU is capable of.
It was developed as part of the Great Internet Mersenne Prime Search (GIMPS), in which the processor is used to find large prime numbers. Prime95 is one of the most well-known free CPU stress tests out there. Here’s the list of four favorite CPU stress tests.

It’s so important that we have an entire guide on how to check your CPU’s temperature. These can be a valuable resource for making sure your cooling solution is doing its job as these stress tests push your CPU quite literally to the limit. It’s usually a good idea to run tests for at least an hour or two, though some can take longer.īefore starting these tests, we’d highly recommend tools like HWMonitor, HWiNFO64, or Core Temp for keeping track of CPU temperature, clock speeds, and power. You want to see how long it takes before it becomes unstable. The goal of stress testing is to push the computer to failure.
