7 best HWMonitor alternatives for PC in 2026 (sensor tools, ranked)
HWMonitor from CPUID is the free tool most guides point at when a Windows PC needs a temperature readout. It reads CPU, GPU, and chipset sensors, shows minimum, current, and maximum values, and runs from a portable download. Where HWMonitor alternatives come in is depth. The free HWMonitor sensor list is narrower than HWiNFO’s, logging beyond text export lives in the paid HWMonitor Pro, and the interface has not changed in a decade. On a workstation with new AMD or Intel silicon, the reference sensor data usually comes from a different tool.
The picks below cover the exhaustive sensor tool, the paid workstation reference, the open-source Windows and Linux options, the GPU-specialized monitor, and the classic tools people install by muscle memory. Each is judged on sensor breadth, sensor accuracy on modern chips, logging, and how quickly the answer lands.
Quick comparison
| Tool | Best for | Platforms | Price | Standout feature |
|---|---|---|---|---|
| HWiNFO | Deepest sensor list | Windows | Free | Live logging and alerts |
| AIDA64 Extreme | Workstation reference | Windows | Paid | Sensor stream to LCD panels |
| LibreHardwareMonitor | Actively maintained open source | Windows, Linux | Free | Home Assistant and Grafana exporters |
| OpenHardwareMonitor | Classic open source | Windows | Free | Long-running community project |
| MSI Afterburner | GPU sensors and OC | Windows | Free | On-screen overlay in games |
| Core Temp | Focused CPU thermal | Windows | Free | Small footprint, taskbar view |
| SpeedFan | Fan control | Windows | Free | Rule-based fan speed |
Why people leave HWMonitor
The core sensor list is stable but narrow. On modern Ryzen platforms HWMonitor sometimes lags the AMD chipset driver releases, so a new board reads the CPU socket but misses the correct effective clock or the AM5 CCD temperature. The interface is a treeview that has not changed in years. Logging beyond a plain-text dump requires the paid HWMonitor Pro, and there is no on-screen overlay for gamers. Users on r/AMDHelp and the Overclock.net forum also mention that the tool tends to enumerate every voltage as an unlabeled generic entry on non-major boards, which makes the sensor list hard to read without cross-checking a datasheet. The alternatives below either expand the sensor list, add the on-screen overlay, or ship a proper logging service.
The alternatives
HWiNFO, deepest sensor list on Windows
HWiNFO reads more sensors than any other free tool on Windows and stays current with new hardware faster than HWMonitor. Every voltage, temperature, current, and fan is enumerated and labeled, and the sensor window supports live logging to CSV, custom alerting, and a compact taskbar view.
Where it falls short: The sensor window is dense until you customize it. Windows-only.
Pricing: Free for personal use, paid Pro tier for business.
Download: HWiNFO
Bottom line: For most Windows users, HWiNFO is the direct upgrade from HWMonitor.
AIDA64 Extreme, workstation reference
AIDA64 Extreme is the paid commercial audit and sensor tool. Sensor coverage matches HWiNFO on most systems, and the tool integrates with LCD panels on Corsair, MSI, and NZXT hardware to display live sensor data outside the OS. Benchmark modules add memory and cache speed tests.
Where it falls short: Paid, and the interface has not been redesigned in years.
Pricing: Paid, one-off license per install.
Download: AIDA64 Extreme
Bottom line: For shops already running AIDA64, staying with it is fine.
LibreHardwareMonitor, actively maintained open source
LibreHardwareMonitor forked OpenHardwareMonitor and has kept the sensor coverage current with new Intel and AMD platforms. Exporters for Home Assistant, Grafana, and MQTT let the tool feed a dashboard directly.
Where it falls short: The UI is functional, not friendly, and some brand-new hardware waits for a release.
Pricing: Free.
Download: LibreHardwareMonitor
Bottom line: For a free sensor tool that pushes data to a dashboard, this is the pick.
OpenHardwareMonitor, classic open source
OpenHardwareMonitor was the community reference for years. It still runs on older Windows builds and older hardware and pairs with tools that use its data format.
Where it falls short: Development has slowed. Modern platforms are better read by the LibreHardwareMonitor fork.
Pricing: Free.
Download: OpenHardwareMonitor
Bottom line: On older builds where the fork does not fit, the classic still runs.
MSI Afterburner, GPU sensors and OC
MSI Afterburner is the tool overclockers pair with a GPU. Real-time sensors, custom fan curves, and an on-screen overlay in games all ship in one client. Combined with RivaTuner Statistics Server, it becomes the reference in-game overlay tool.
Where it falls short: GPU-focused. CPU and chipset sensors are read through OSD extensions rather than in the base tool.
Pricing: Free.
Download: MSI Afterburner
Bottom line: For gamers who care about GPU temperatures, MSI Afterburner is standard.
Core Temp, focused CPU thermal
Core Temp reads CPU package temperatures from the on-die sensors and shows them as taskbar icons. Tiny footprint, no bundled extras, and the plugin ecosystem is small but functional.
Where it falls short: CPU-only. GPU, chipset, and storage are out of scope.
Pricing: Free, with an optional donation.
Download: Core Temp
Bottom line: For a CPU-only readout in the taskbar, Core Temp is the shortest path.
SpeedFan, fan control
SpeedFan is the tool people install when a case fan will not slow down. Rule-based fan control with sensor targets, PWM outputs on supported boards, and hard drive temperature triggers all ship in one client.
Where it falls short: UI has not changed in years, and modern motherboards are increasingly hard to speak to without the vendor tool.
Pricing: Free.
Download: SpeedFan
Bottom line: On older builds where the BIOS fan control is not enough, SpeedFan still wins.
How to choose
Pick HWiNFO when the goal is the deepest sensor coverage on Windows. Pick AIDA64 when the shop already owns it or an LCD sensor panel is in play. Pick LibreHardwareMonitor when a dashboard needs sensor data. Pick OpenHardwareMonitor on older builds. Pick MSI Afterburner for GPU sensors and in-game overlay. Pick Core Temp when the taskbar is the interface. Pick SpeedFan when fan control is the whole reason. Stay on HWMonitor when the workflow is a quick min-max readout of familiar hardware, since the tool remains a fast portable snapshot for well-supported PCs.
FAQ
Is HWiNFO better than HWMonitor?
Yes, for sensor coverage, logging, and support of modern platforms. HWMonitor is still smaller and quicker to launch.
Is HWMonitor safe?
Yes. The installer from CPUID is safe. Avoid third-party mirrors that repackage it.
Which sensor tool is the most accurate?
HWiNFO and AIDA64 are the community references for sensor accuracy on modern hardware. LibreHardwareMonitor tracks closely.
Can I monitor GPU temperature with HWMonitor?
Yes, the tool reads the GPU sensors, but the in-game overlay comes from MSI Afterburner and RivaTuner Statistics Server, not from HWMonitor.
Is there an HWMonitor for Linux?
No, but LibreHardwareMonitor runs on Linux, and native tools like lm_sensors cover the sensor readout under KDE and GNOME desktop tools.
