I have been using monitoring software for the better part of a decade, even when I was just using my horrible Acer Aspire, and I have tried a few different programs. I used HWMonitor, CPU-Z, OCCT, Asus Armoury Crate, Gigabyte's Utility, and a few others that I forget the names. So far most do their job, but I settled on HWinfo64 due to it's minimal resource usage, accuracy and reliability.
I do use the Adrenalin overlay on games that do not have an option to display FPS or temps, but I have HWinfo64 running at startup on nearly every machine I build. It helps when those I have built for suffer crashes or freezes so I can rule out hardware temp and power issues. Though it is a rare occurance that a PC I have built for others has issues, I still install it just so I can show people how to see max temps, and other information so they can understand where the performance should be with their build.
What software do you use to monitor your PC, if you use any at all?
In addition to CPU-Z/GPU-Z I also use Core Temp and the Core Temp Gadget with 8GadgetPack on Windows 10. I like having that CPU info realtime on my desktop.
HWInfo64 with customized settings
I use HWinfo64 for hardware monitoring on my PC. It's efficient, accurate, and reliable, with minimal resource usage. It's helpful for diagnosing issues and ensuring optimal performance, especially for gaming as well as social media.
