The HWiNFO64 alternative for Linux gamers
HWiNFO64 is a Windows tool. It does not run natively on Linux, not reliably through Wine or Proton, not for the sensor tree that made it a staple on Windows rigs. If you moved to Linux and miss it, Thermal Canary Pro is the closest equivalent for the thermal-safety side of what HWiNFO64 did for you.
What HWiNFO64 did for you on Windows
- An exhaustive sensor tree: every temperature, voltage rail, and fan header on the board
- A custom, user-configurable logging window and CSV export
- An in-game overlay via RivaTuner Statistics Server (RTSS)
- SMART and drive health reporting alongside thermals
What Thermal Canary Pro does on Linux
| What you used HWiNFO64 for | Thermal Canary Pro equivalent |
|---|---|
| Sensor tree / live monitoring | Real-time CPU/GPU gauges, DIMM heat-bars, fan RPM, on Linux hwmon and NVML |
| "What happened right before it crashed" | Crash Black Box: a 60-second rolling buffer, auto-dumped on GPU crash or an unexpected reboot |
| "Why did my FPS drop" | Throttle Detector: tells you whether it was thermal, power, or voltage limited, in plain English |
| Custom logging / CSV export | Sessions: manual start/stop logging with CSV export and Before/After comparison |
| "Is something degrading over time" | Hotspot Delta Analyzer: tracks GPU edge-vs-junction delta over weeks to catch drying thermal paste |
What Thermal Canary Pro does not try to replace
This is the honest part. HWiNFO64's sensor tree is broader than what Pro shows, and Pro does not compete on either of these:
- Exhaustive voltage-rail and SMART reporting. For that level of detail on Linux, pair Pro with
lm-sensorsandsmartctl. - In-game overlay. If you want an on-screen overlay during gameplay, keep using MangoHud; Pro reads the same sensors and adds forensics on top, it doesn't replace your overlay.
- Motherboard-vendor tuning. Fan curve and voltage tuning still belongs to your board's own tools, or CoreCtrl/GreenWithEnvy on Linux.
Pricing
Thermal Canary Pro is a one-time payment of €49 that unlocks every 1.x release, forever, no subscription. HWiNFO64 is free for personal use on Windows; see REALiX's own site for their current licensing terms, since they can change over time.
FAQ
Does HWiNFO64 run on Linux?
No. HWiNFO64 is a Windows application by Martin Malík / REALiX. It has no native Linux build, and Wine/Proton cannot reliably reach the low-level sensors it depends on, since Windows-only kernel drivers handle that hardware access.
Is Thermal Canary Pro a 1:1 replacement for HWiNFO64?
No. HWiNFO64's sensor tree is exhaustive: dozens of voltage rails, fan headers, and SMART attributes on top of temperature. Thermal Canary Pro focuses on the thermal-safety side of that data (CPU/GPU/DIMM temperatures, fan RPM) and on the diagnostics HWiNFO64 does not do: crash forensics, throttle-cause detection, and long-term degradation tracking.
What does Thermal Canary Pro do that HWiNFO64 does not?
HWiNFO64 logs numbers. Pro interprets them: a Crash Black Box that auto-dumps the 60 seconds before a GPU crash, a Throttle Detector that says whether an FPS drop was thermal, power, or voltage limited, and a Hotspot Delta Analyzer that tracks GPU edge-vs-junction temperature drift over weeks to catch drying thermal paste before it fails.
How much does Thermal Canary Pro cost compared to HWiNFO64?
Thermal Canary Pro is a one-time payment of €49 that unlocks every 1.x release forever. HWiNFO64 is free for personal use on Windows; check REALiX's own site for their current licensing terms.
Can I use Thermal Canary Pro alongside MangoHud or lm-sensors?
Yes. Thermal Canary Pro reads the same hwmon/NVML sensor data as MangoHud and lm-sensors, it does not replace them. Keep MangoHud for the in-game FPS overlay if you already use it. Pro adds the layer neither tool has: why a crash happened, and whether your hardware is degrading.
