HWMonitor by CPUID — Precise Hardware Monitoring for Windows PCs

HWMonitor is a compact, low-overhead system monitoring tool from CPUID that exposes live sensor data across CPUs, GPUs, motherboards and storage on Windows (x86/x64). Favored by enthusiasts, system builders and IT technicians, HWMonitor focuses on accurate temperatures, voltages, fan speeds, power and current readings with a clear, no-frills interface and both installer and portable ZIP distributions.

What Sensors and Hardware HWMonitor Covers

• CPU and GPU telemetry: Per-core clocks, per-core and package temperatures, utilization and per-core turbo behavior for modern Intel (including Core Ultra) and AMD Ryzen processors, plus NVIDIA and AMD GPU sensors.
• Motherboard sensor ICs: Readouts from common LPCIO chips (ITE, Winbond, Nuvoton) for voltages, fan RPMs and system thermals.
• Memory and storage: DIMM thermal sensors when present and SMART attributes for HDDs/SSDs to monitor health trends.
• Power and currents: Component-level power draw and current measurements where the platform exposes them.
• Battery and peripherals: Laptop battery health, charge cycles and additional device sensors if available via ACPI or vendor APIs.

Key Features and Benefits

• Lightweight and portable: Available as an installer or zip package for quick deployment on test benches and service tasks.
• Accurate, real-time monitoring: Live refresh of temperatures, voltages, fan RPM and power to detect overheating, PSU instability or fan failure.
• Detailed logging and export: Save full sensor snapshots and continuous logs to text files for diagnostics, bug reports or warranty claims.
• Wide hardware support: Regular updates add support for new CPUs, GPUs, chipsets and memory modules to keep readings current.
• HWMonitor PRO option: Remote monitoring, advanced logging and additional features for technicians and IT teams who need networked access and extended history.

Installation, Updates and Compatibility

HWMonitor ships as separate 32-bit and 64-bit installers plus a portable ZIP archive. Installation is straightforward and reversible through Windows Settings or Control Panel; the portable build runs without installing. CPUID maintains an active changelog and frequent releases with added support for new Intel and AMD microarchitectures, GPUs and sensor chips to maintain compatibility with current hardware.

Who Should Use HWMonitor

• PC builders and overclockers: Track temperatures, voltages and fan behavior while tuning performance or stress-testing configurations.
• IT administrators and service techs: Generate sensor reports and logs for troubleshooting hardware failures and warranty claims.
• Enthusiasts and gamers: Monitor thermal headroom and ensure adequate cooling during extended gaming sessions or benchmarks.

Practical Notes and Tips

• Interpreting CPU usage: Values can exceed 100% in some internal counters; this reflects how HWMonitor reports aggregated core counters rather than Windows Task Manager style percentages.
• Fast core marking: An asterisk (*) marks faster cores that may run at higher turbo clocks; use this to correlate temperature and frequency behavior.
• PCIe counters and diagnostics: Some PEX transfer counters increment during link speed/width changes and aren’t necessarily errors; monitor established PCIe error counters for real issues.
• Use PRO for remote needs: Consider HWMonitor PRO for remote sensor access, continuous centralized logging and enhanced support in multi-machine environments.
