About HWiNFO
HWiNFO is a hardware analysis and monitoring program for Windows. It identifies processors, graphics cards, drives, memory, mainboards and many other components, and shows live sensor readings such as temperatures, fan speeds, voltages and power use.
Its sensor window can log to files, feed an on-screen display through tools like RivaTuner Statistics Server and integrate with other monitoring software. Release notes for the latest version list added reporting for new hardware, fixes to sensor readings and options such as inserting notes into the JSON sensor log.
HWiNFO suits PC builders, overclockers, technicians and gamers who want to see exactly what is inside a machine and how it behaves under load. The amount of data is large, so newcomers may want to start with the summary view.
The software is distributed as proprietary freeware, and the publisher offers separate options for commercial use. See the official site for details of each version, including the portable edition.
Choose the Sensors-only mode if you just want to monitor temperatures. Update it regularly to stay compatible with new hardware.
