Best Free Hardware Monitoring Tools

Apps that regulate your rig’s internals

Making sure your rig’s temperatures, hardware, and clock speeds are running correctly is a good way to monitor your PC’s health. We always recommend stress-testing your shiny-new rig, or checking your hardware if you experience any stability issues that occur out of the blue. We’ve gathered up a list of the best free utilities you can use to make sure you have a healthy PC.

CPU-Z tells you what’s going on with your CPU by giving you readouts of your Core Speed, Multiplier, Bus Speed, and your different cache levels. It also tells you the make and model of your motherboard and video card, along with your RAM speed and capacity.

We recommend using this tool if you have a preconfigured system from an OEM like Lenovo, HP, or Dell and need to find out your motherboard’s model number (if it isn’t printed on the board). The tool can also be used to monitor your CPU’s voltage, so it's overclocker friendly.


GPU-Z gives you detailed readouts of your GPU’s clock speeds and memory size. You can use this tool to make sure that your video card is running at PCIe 3.0, as some boards run in 2.0 instead of 3.0 by default. You’ll look at the Bus Interface box to check out your video card's PCIe configuration.


Got GPU problems? Furmark is a fantastic tool if you’re getting blue screens during games and want to find out if your video card is the culprit. The utility gives your GPU a workload to max-out your video card. You’ll also see a temperature read from it, so you can see if your card is running hot.


Getting weird frame rate issues after freshly installing BF4 or Assassins Creed Black Flag? FRAPS will give you readouts of your real-time frame rate in-game, so you can see when and where you rig is starting to stutter. We like using this utility when a game is running poorly, so we can keep an eye on our frame rate during gameplay. We also use this tool to capture average frame rates of games that don’t come with benchmarking tools like BF4, Far Cry 3, and Crysis 3.
