SpeedFan

SpeedFan is a hardware monitoring tool that gives you real-time visibility into your PC's temperature, voltage, and fan speed. Watch CPU, GPU, motherboard, and storage device temperatures at a glance, along with live voltage readings and fan RPM data across all system components.

The main monitoring dashboard displays CPU usage, fan rotation speeds, and temperatures for every component in your system. Below that, you'll see real-time voltage levels and the percentage at which each fan is spinning. If your fans support PWM control—those with four-pin connectors wired to compatible motherboard headers—you can adjust fan speeds directly. This lets you experiment with how fan speed changes affect component temperatures and system noise in real time.

Beyond basic readings, this tool offers control over select motherboard and chipset settings. Build custom monitoring screens that display only the data you care about most. The SMART section shows the health status of your storage drives, while the graphs view tracks temperature changes over seconds and minutes so you can spot trends.

One of the most useful features is the taskbar integration: pin any component's temperature to your Windows taskbar and monitor it without opening the full application. This keeps thermal data visible during gaming, work, or any demanding task.

SpeedFan serves enthusiasts who want to optimize cooling performance, overclockers who need to track thermal limits, and anyone concerned about PC longevity and component health. System builders can use it during setup to verify all fans are spinning correctly and temperatures are within safe ranges. Laptop users can monitor whether their cooling system is working properly and adjust expectations during intensive use.

Whether you're troubleshooting unexpected shutdowns, validating a new cooler installation, or simply keeping tabs on system health, this monitoring suite gives you the visibility you need. Download SpeedFan today and take control of your PC's thermal management.
