HWMonitor

HWMonitor is a focused hardware-sensor utility for checking the health of PCs and supported Android devices. It suits users who need component telemetry rather than a software inventory, with the free Windows edition covering routine checks and PRO editions adding remote access and retained monitoring data.

Its broad sensor coverage and portable downloads make it a practical first stop for diagnosing temperatures, power behavior, fan response, storage activity, and similar hardware questions. Choose elsewhere if you need installed-software inventory or a Linux-native monitor.

Overview

HWMonitor brings voltages, temperatures, power, current, fan speed, utilization, and clock speeds into a hardware-centered view. It can read CPU and GPU sensors, supported LPCIO chips, memory modules that expose thermal sensors, S.M.A.R.T. storage devices, and batteries. That range is valuable when investigating overheating, throttling, charging behavior, or drive activity, but readings naturally depend on the sensors exposed by each machine.

The current Windows release is version 1.68 for x86/x64, offered as both an installer and a ZIP package. CPUID also provides a separate Windows ARM64 download. Version 1.68 adds PCI Express error counters for AMD and Intel GPUs, NPU and platform metrics, HDD IOPS and average latency, and preservation of the device and sensor-tree state. CSV logging extends the utility beyond a momentary snapshot.

Key features

• Detailed component telemetry: CPU, GPU, battery, storage, memory thermal sensors, and motherboard-related LPCIO readings give technically minded users a single place to inspect system health. It is a monitoring tool, not a catalogue of installed applications.
• Recent diagnostic metrics: GPU PCI Express error counters, NPU and platform values, plus HDD IOPS and average latency make the 1.68 release more useful for tracing performance and hardware faults than a basic temperature viewer.
• Logging: CSV logging lets you retain readings for later comparison, while saved device and sensor-tree state avoids rebuilding a preferred view between sessions.
• Remote monitoring in PRO: HWMonitor PRO connects to distant PCs and Android devices over TCP/IP. This is the important upgrade for administrators or anyone checking machines away from the desk.
• Graphs and interface controls: PRO can save monitoring data, create bitmap logging graphs, place sensors in the system tray, and use editable sensor labels. Those controls make recurring observation easier than repeatedly reading a raw sensor tree.
• Android monitoring: HWMonitor PRO for Android reports device temperatures, battery voltage, battery temperature and charge, CPU clock and utilization, and GPU clock where the device supports it. Android can monitor up to 10 Windows PCs or Android devices, and remote Android connections require a local Wi-Fi network.
• Technical access: A portable version, HTML report export, command-line interface, and firmware details support scripted checks and documentation alongside the graphical monitor.

Pricing

HWMonitor: free. The Windows x86/x64 edition covers PC hardware-sensor monitoring at no cost, making it the sensible starting point for one-off checks and local troubleshooting.

HWMonitor PRO Standard: $19.95 USD once, with unlimited usage, one year of unlimited updates, and up to 10 remote connections. It fits a small set of machines or a user who specifically needs remote viewing, graphs, tray icons, or editable labels.

HWMonitor PRO Extended: $34.95 USD once, with unlimited usage, two years of unlimited updates, and up to 20 remote connections. The extra cost is justified when the 10-connection ceiling is too restrictive or a longer update period matters; Standard is the leaner choice for smaller deployments.

The PRO registration trial lasts 30 days, although the stated delay can vary, and includes all registered features. The one-time prices are not subscriptions, but updates are unlimited only for the period attached to each edition.

Platforms

HWMonitor supports Windows and Android. Windows users get x86/x64 installer and ZIP packages plus a distinct ARM64 build. Android remote monitoring is constrained to a local Wi-Fi network, and the Android application’s remote device count is capped at 10.

Who it's for

HWMonitor is a strong fit for PC builders, troubleshooters, enthusiasts, and support staff who need direct sensor values without paying for local monitoring. PRO Standard suits people supervising up to 10 remote endpoints; Extended is aimed at larger sets of up to 20. Android users benefit when phone and PC readings need to be viewed together, provided the local-network requirement works for them.

It is a poor match for software-inventory work, and Linux users should look at a platform-specific alternative instead.

Pros and cons

Pros

• Wide coverage across CPU, GPU, storage, battery, memory thermal sensors, and motherboard-related chips.
• Free Windows edition with installer, ZIP, and ARM64 options.
• Version 1.68 adds useful GPU error, NPU, platform, and storage-latency metrics.
• PRO adds TCP/IP remote monitoring, bitmap graphs, tray icons, and label editing.
• Portable use, CSV logging, HTML export, and a command-line interface support repeatable diagnostics.

Cons

• Sensor availability varies with hardware, so coverage is not uniform across PCs or Android devices.
• Remote monitoring and saved PRO features require a paid edition after the 30-day trial.
• Android remote connections require local Wi-Fi, and Android monitoring is limited to 10 devices.
• The tool focuses on hardware readings and does not provide installed-software inventory.

Alternatives

Browse System Information Software for broader system-information tools, or Hardware Monitoring Software for a wider hardware-monitoring shortlist.

• Fastfetch is a free, MIT-licensed command-line utility with more than 75 system-information modules across Android, Linux, macOS, and Windows; choose it for concise inventory output rather than live sensor monitoring.
• Facter is free below 25 nodes and supports Linux, macOS, self-hosted deployments, and Windows; it is the better direction for cross-platform node facts and larger managed environments.
• ASTRA32 offers a free non-commercial Windows plan; choose it when hardware identification is the priority.
• EtreCheckPro is a macOS diagnostic utility with a free download and a $19.99 one-time Power User upgrade; pick it for Mac-focused reports.
• htop is a free Linux/macOS process viewer; choose it when process and resource activity, rather than broad sensor coverage, is the main concern.
• hw-probe is a free Linux and self-hosted project for anonymously collecting hardware details and collaborative troubleshooting.
• Network Activity Indicator is a free Windows utility for displaying network activity, not a replacement for HWMonitor’s component sensors.
• SIW provides Windows system information with a free viewer and a 14-day trial option; choose it when inventory and diagnostics are more important than continuous sensor monitoring.

Verdict

Choose HWMonitor for focused, wide-ranging hardware telemetry on Windows, especially when the free edition is enough or PRO’s remote connections and graphs solve a specific monitoring need. Look elsewhere for installed-software inventories, Linux-first workflows, or diagnostics centered on a different platform.
