Is your PC running hotter than usual? A common culprit is a malfunctioning fan. This article will guide you through several ways to check if your computer's fans are spinning correctly, helping you diagnose potential overheating problems. Knowing how to check your fans is a crucial part of PC maintenance.

Visual Inspection: The Easiest Check

The simplest method is a visual inspection. Power on your PC and carefully observe your computer case. You should see fans spinning inside.

  • Front Panel: Many cases have fans at the front, drawing in cool air.
  • Rear Panel: A rear exhaust fan expels hot air.
  • CPU Cooler: The CPU cooler (often a heatsink with a fan) is usually located near the center of the motherboard.
  • GPU Cooler: Dedicated graphics cards (GPUs) also frequently have their own fans.

Important Note: Always ensure your PC is unplugged or the power supply is switched off before opening the case to avoid electrical shock.

Using PC Monitoring Software

Software provides a more precise and detailed way to check fan speeds and temperatures. Several free and paid options are available.

Popular PC Monitoring Software:

  • SpeedFan: This free utility can monitor fan speeds, temperatures, and voltages. It has a relatively steep learning curve, but is powerful.
  • HWMonitor: A straightforward and easy-to-use program that displays real-time sensor data, including fan speeds and temperatures.
  • MSI Afterburner (for GPUs): Primarily for overclocking, Afterburner also provides comprehensive fan control and monitoring for your graphics card.
  • BIOS: Your computer's BIOS (Basic Input/Output System) often provides basic fan speed information, though it might not display all your fans. Accessing your BIOS usually requires pressing a specific key (like Delete, F2, or F12) during startup.

These programs typically show you:

  • RPM (Revolutions Per Minute): Indicates how fast the fan is spinning. A reading of 0 RPM means the fan isn't spinning.
  • Fan Speed Curve: This is a graph which shows the fan speed based on the temperature.
  • Temperature Readings: Checking temperatures alongside fan speeds helps determine if the fans are working efficiently. High temperatures with low fan speeds indicate a problem.

Listening for the Fans

While not as precise as software monitoring, you can often hear your fans running. If you hear no sound or an unusual sound coming from the case, it's worth investigating further.

  • Silence: No sound could indicate a non-spinning fan.
  • Unusual Noises: Grinding, clicking, or whirring noises may suggest a failing fan bearing.

What to do if your PC fans aren't spinning

If you’ve confirmed a fan isn't spinning, take these steps:

  • Check Connections: Carefully inspect the fan's power connector and ensure it's firmly attached to the motherboard or power supply. Reseat the connector if necessary.
  • Check the Fan Itself: If the fan is unplugged, inspect the fan blades and surrounding areas for obstructions or damage. If the fan is physically damaged, it will need replacement.
  • BIOS Settings: Check your BIOS settings to ensure fan control isn't disabled.
  • Driver Issues (Less Likely): In rare cases, driver issues could affect fan control. Update your motherboard drivers.
  • Replace the Fan: If all else fails, you'll likely need to replace the faulty fan. Note: Replacement fans should have compatible specifications (voltage, size, connector type).

Regularly checking your PC fans is an important part of preventative maintenance. Catching potential issues early can prevent overheating, system crashes, and even hardware damage. Remember to consult your PC's manual or the manufacturer's website for specific guidance on your model.
