HWMonitor

HWMonitor is a focused sensor reader for Windows PCs, with an Android companion and paid PRO editions. It suits users diagnosing temperatures, power, fans, clocks, storage, or battery behavior rather than cataloguing every installed program. The free Windows edition covers routine checks, while PRO is aimed at people who need remote screens, longer-term records, or a larger device set.

Overview

HWMonitor brings voltage, temperature, power, current, fan-speed, utilization, and clock-speed readings into a single hardware view. It covers CPUs, GPUs, supported LPCIO chips, memory modules that expose thermal sensors, S.M.A.R.T. storage devices, and batteries. That breadth is valuable when troubleshooting a component or watching a machine under load, but readings naturally depend on the sensors and hardware your system exposes.

Windows version 1.68 is offered for x86/x64 as an installer or ZIP archive, and CPUID provides a separate ARM64 download. The release adds PCI Express error counters for AMD and Intel GPUs, NPU and platform metrics, HDD IOPS and average latency, and retention of the device and sensor-tree state. CSV logging is included, extending the utility beyond a momentary glance.

Key features

• Broad component coverage: CPU and GPU telemetry sits alongside battery, memory-thermal, storage, and motherboard-controller readings, making the app useful for hardware fault-finding and thermal checks.
• Storage and graphics diagnostics: HDD IOPS, average latency, and GPU PCI Express error counters add context that basic temperature-only monitors miss, particularly for investigating storage slowdowns or link errors.
• Retained views and logs: Saved device and sensor-tree state keeps a preferred view intact, while CSV logging lets you preserve readings for later review.
• PRO remote monitoring: PRO can watch distant Windows PCs and Android devices over TCP/IP. It also saves monitoring data and creates bitmap logging graphs, with tray icons and editable sensor labels for a more persistent desktop workflow.
• Android reporting: The PRO Android app reports device temperatures, battery voltage, battery temperature and charge level, CPU clock and utilization, and GPU clock on supported hardware. Android remote connections require a local Wi-Fi network and the app can monitor up to 10 Windows PCs or Android devices.
• Portable and command-line options: A ZIP distribution supports portable use, and a command-line interface is available. HTML report export is listed for users who need a shareable summary.

Pricing

The HWMonitor plan costs free and covers Windows x86/x64 PC hardware sensors. It is the sensible choice for one-off checks, routine maintenance, and anyone who does not need remote access.

HWMonitor PRO Standard costs $19.95, paid once. It includes unlimited usage, one year of unlimited updates, and up to 10 remote connections. This fits a home lab or small group of machines, although the update entitlement is limited to that first year.

HWMonitor PRO Extended costs $34.95, paid once, with two years of unlimited updates and up to 20 remote connections. It is the better buy for a larger set of systems or a longer refresh cycle. PRO registration includes a trial of all registered features for 30 days, although the registration page notes that the exact delay can vary.

Platforms

HWMonitor supports Windows and Android. Windows has x86/x64 and ARM64 downloads, plus installer and ZIP formats. Android monitoring is delivered through HWMonitor PRO; remote Android connections operate on a local Wi-Fi network.

Who it's for

Choose HWMonitor if your priority is live, component-level telemetry on a Windows machine, especially when investigating heat, fan behavior, power draw, storage latency, or GPU link errors. The free edition is well matched to individual PC owners and technicians who need readings without a recurring fee. PRO is justified when several PCs or Android devices must be watched remotely, or when saved graphs and labeled tray sensors matter. It is a poor fit if your main need is installed-software inventory or a Linux-first monitoring tool.

Pros and cons

Pros

• Wide sensor scope: CPU, GPU, storage, battery, memory-thermal, and controller readings support varied troubleshooting tasks.
• Useful recent additions: NPU, platform, PCI Express error, IOPS, and latency metrics deepen diagnostics in version 1.68.
• Flexible Windows delivery: Installer, ZIP, and ARM64 downloads cover conventional and portable setups.
• Clear PRO upgrade path: Remote connections, graphs, labels, and tray icons address monitoring beyond a single local screen.

Cons

• Hardware-dependent coverage: Unsupported sensors or devices will limit what appears, so it cannot guarantee a complete picture on every PC.
• Remote features are paid: The free plan does not provide PRO’s remote monitoring or saved-graph workflow.
• Android remote use is network-bound: Connections require local Wi-Fi, reducing usefulness away from the same network.
• Not an inventory suite: Its emphasis is hardware telemetry, not installed-software reporting.

Alternatives

• Fastfetch is the better pick for a free, MIT-licensed command-line tool with more than 75 system-information modules across Android, Linux, macOS, and Windows.
• Facter suits cross-platform or self-hosted inventory, with a free plan for fewer than 25 nodes.
• ASTRA32 is a Windows alternative with a free non-commercial plan.
• hw-probe fits Linux or self-hosted users who want hardware details collected for collaborative debugging.
• SIW offers Windows system-information editions, including a free viewer and a 14-day trial version.
• EtreCheckPro is the macOS choice, with free basic reports and diagnostics plus a paid power-user package.
• htop is a free Linux/macOS process monitor rather than a full sensor reader.
• Speccy is a Windows freemium option for advanced PC insights, with a free home-use edition and a paid professional tier.

Verdict

HWMonitor is the right recommendation for Windows users who want broad, direct hardware-sensor readings at no cost. Choose PRO when remote device access, retained logs, graphs, or more than one monitored system are central to the job. Look elsewhere for software inventories, Linux-centric workflows, or monitoring that must work beyond a local Wi-Fi network on Android.
