OpenHardwareMonitor reads sensor data directly from the motherboard, CPU, GPU, and drives to provide live telemetry on system health. It displays per-core temperatures, clock frequencies, fan RPMs, voltage rails, and hardware utilization without requiring drivers or elevated privileges. Built as a portable .NET application, it leaves no system footprint and operates entirely in user space. Designed for system integrators, stability testers, and power users who need reliable, open diagnostics—its source code is publicly auditable, and it integrates cleanly into automated logging or remote monitoring setups.
