Slow down your CPU or GPU by increasing power consumption.

Welcome to CPU Grab Ex, the ultimate tool for testing the limits of your central processing unit, aka the CPU. Why would you need such a tool, you might ask? Well, if you're a power user who needs to push your computer to the max, or if you're an enthusiast who likes to tinker with your hardware, then this is the tool for you.

So, what is CPU Grab Ex all about, and how can it help you? Let's dive into it. As you may already know, computers generate a lot of heat, and they rely on a cooling system to keep temperatures under control. But sometimes, the cooling system may not be sufficient, and the heat generated by the CPU may become too much to handle. This can cause your PC to become unstable, or even lead to hardware failure.

CPU stress-testing software for enthusiasts

That's where CPU Grab Ex comes in. It can stress-test your CPU and detect potential hardware failures before they become a serious problem. With CPU Grab Ex and a temperature monitor application, you can quickly and easily learn about your computer's behavior whenever the CPU is put to work.

But be careful, as stressing your CPU too much can cause your computer to become unresponsive. That's why CPU Grab Ex allows you to select how much of the CPU cores to put on stress, with a default value of 50%. You can use a slider control to change the stress level and make sure you don't overdo it.

Test as many cores as you'd like

CPU Grab Ex also offers two options for starting the stress process. You can either "Grab" and stress all the CPU cores, or "Grab only the selected cores" and stress only the selected ones. It will show you the usage level of each core along with a graphical chart. And if your GPU supports OpenCL, CPU Grab Ex can also stress the GPU cores.

In closing

All in all, CPU Grab Ex is a pretty good tool to add to your hardware testing arsenal. It's easy to use and can quickly load the CPU cores in seconds. It's an ideal tool for testing how the CPU is behaving under stress. If you're a power user, an enthusiast, or just want to make sure your computer is protected against overheating and every bad aspect related to this issue, then CPU Grab Ex is the tool for you.
