Why This Matters

HWiNFO64 remains a go-to free utility for deep, real-time visibility into PC hardware, from CPU and GPU temperatures to VRM readings and voltages. For enthusiasts overclocking or troubleshooting stability, that level of sensor detail and logging is hard to get elsewhere, and its broad Windows compatibility keeps it accessible to older systems too.

Key Takeaways
Worth a Look

Thermal Grizzly Kryonaut Thermal Grease — If HWiNFO64 is showing CPU package temps creeping higher than you'd like, a fresh application of Thermal Grizzly Kryonaut is the classic next step. It's a favorite among overclockers and builders for reseating coolers, and you can watch the before-and-after right in HWiNFO's sensors view.

HWiNFO64 offers comprehensive, real-time data on every component in your PC, including CPU, GPU, motherboard, RAM, drives, sensors, and more. With highly detailed reports, customizable alerts, and extensive logging features, HWiNFO64 is trusted by enthusiasts, system integrators, and IT professionals alike.

Whether you're benchmarking, overclocking, or ensuring system stability, HWiNFO64 delivers accurate and up-to-date hardware insights in a clean, configurable interface.

Which values should I monitor when using HWiNFO64?

The most useful readings to track are CPU core temperatures, CPU package temperature, GPU temperature, VRM temperatures, and key voltages. For AMD CPUs, Tdie or Tctl is commonly used; for Intel, the highest core temperature is important. The "Sensors only" mode gives a focused view, and enabling logging helps track performance or diagnose issues over time.

Is HWiNFO CPU and GPU temperature accurate?

Yes, HWiNFO data is reliable and accurate and will inform you about everything it possibly can about your computer. The information is split in 3 windows: a system summary, a full report, and active sensor readings.

Can HWiNFO64 show VRM temperatures?

Yes, HWiNFO64 can monitor VRM temperatures if your motherboard provides access to that data. VRM temperatures often appear labeled as "VRM" or "MOS" in the sensors list. If no such label appears, it's likely your motherboard doesn't include a sensor for that component.

Can HWiNFO control fans?

Technically, yes, HWiNFO shows you real-time data on hardware components and allows you to manually control fan speeds. However, you must use this feature carefully. HWiNFO was primarily designed to show system information. If you're looking to control CPU and GPU fan speeds you should take a look at SpeedFan or FanControl, which are specialized tools, both are free and have been tested extensively.
