HWMonitor is a lightweight PC hardware monitoring tool that reads your system’s main health sensors live: temperatures, voltages, power, currents, fan speeds, utilization and clock speeds. Used by enthusiasts and IT staff alike, it lets you track CPU package and core temps, GPU and storage temperatures (where supported), and more.

Features

See what makes HWMonitor a solid choice for system sensor monitoring on Windows.

Temperatures:

• CPU package and per-core temps, GPU temps, and motherboard sensors where your hardware exposes them.
• SSD and HDD temperatures via S.M.A.R.T. to catch overheating storage early.
• RAM modules with thermal sensors, plus other on-die or board sensors your system provides.

Voltages, Fans, Power & Clocks:

• Voltage, fan speed and power/current readings for CPU, GPU and motherboard when supported.
• CPU and GPU clock speeds and utilization in a single tree-style view.
• Battery status and LPCIO support (ITE IT87, Winbond, Nuvoton) and other sensor hardware.

Export & Logging:

• Export a full sensor report as text from the File menu for diagnostics or support.
• CSV logging in recent versions to record sensor data over time.
• Share exported reports with support or forums for precise help from your readings.

Portable ZIP vs Installer:

• Portable ZIP runs from any folder or USB stick with no installation.
• Installer adds Start menu shortcuts and uninstall via Add or Remove Programs.

Registry and command-line reference

The Windows registry holds hardware and system configuration data. Admins often check these paths when verifying what monitoring tools such as HWMonitor show.

HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

wmic cpu get Name,NumberOfCores,NumberOfLogicalProcessors
wmic diskdrive get Model,Size,Status
wmic baseboard get Manufacturer,Product,SerialNumber
wmic PATH Win32_VideoController get Name,AdapterRAM
Get-CimInstance Win32_OperatingSystem | Select-Object Caption,Version,OSArchitecture

Combine HWMonitor with these registry paths and CLI commands when documenting a system, planning upgrades, or filing support tickets so technicians see your exact PC configuration.
