HWiNFO – Comprehensive Hardware Monitoring and Analysis

What is HWiNFO?

HWiNFO (Hardware Information) is a free, professional-grade hardware monitoring and diagnostic tool for Windows that provides the most comprehensive hardware information available. Developed by Martin Malík since 1995, HWiNFO has become the gold standard for system monitoring among overclockers, hardware enthusiasts, and IT professionals.

Unlike simple tools like Windows Task Manager, HWiNFO shows you everything about your hardware: CPU temperatures per core, GPU metrics, motherboard sensors, fan speeds, voltages, power consumption, and hundreds of other parameters in real-time. It supports the latest hardware the day it’s released and provides data that even manufacturer software often misses.

HWiNFO is completely free (though donations are welcomed), portable, and can run in the background with minimal resource usage. It can log sensor data, export reports, integrate with monitoring overlays like RTSS (RivaTuner Statistics Server), and provides data to third-party monitoring tools. For anyone serious about understanding their computer’s hardware, HWiNFO is indispensable.
