If your PC fan has decided to take a permanent break, leading to a “ca ch sưa fan case ko quay” (how to fix a non-spinning case fan) situation, you’ve come to the right place. A non-spinning fan can spell disaster for your computer, leading to overheating and potential hardware damage. This article will guide you through the common causes and solutions to get your cooling system back on track.
Common Causes of a Non-Spinning PC Fan
Several factors can contribute to a PC fan refusing to spin. From simple loose connections to more complex hardware failures, understanding the root cause is crucial for effective troubleshooting.
Loose or Disconnected Cables
The most common and often overlooked culprit is a loose or disconnected power cable. Check the connection between the fan and the motherboard or power supply unit (PSU).
Dust Buildup
Over time, dust accumulates within the fan, hindering its movement and eventually leading to a complete standstill. A thorough cleaning can often resolve this issue.

Failed Fan Motor
Unfortunately, the fan motor itself can fail due to wear and tear or manufacturing defects. If this is the case, replacing the fan is the only solution.
BIOS Settings
Incorrect BIOS settings can sometimes interfere with fan operation. Checking and adjusting the fan control settings in the BIOS might be necessary.
Motherboard or PSU Issues
In rare cases, a faulty motherboard or PSU can prevent the fan from receiving power. This requires more advanced troubleshooting or professional assistance.
How to Fix a Non-Spinning PC Fan
Now that we’ve identified the potential causes, let’s delve into the solutions for a “ca ch sưa fan case ko quay” scenario.
Check the Power Connection
Ensure the fan cable is securely connected to both the fan itself and the power source (either the motherboard or PSU). Try reseating the cable to ensure a proper connection.
Clean the Fan
Use compressed air to remove dust buildup from the fan blades and surrounding area. Be careful not to apply excessive pressure, as this can damage the fan.
Test the Fan with a Different Power Source
If you have a spare power connector, try connecting the fan to it to determine whether the original power source is the issue. Alternatively, you can connect the fan to another computer to test its functionality.
Check BIOS Settings
Enter your computer’s BIOS and navigate to the fan control settings. Ensure the fan is enabled and configured to operate correctly. Consult your motherboard manual for specific instructions.
Replace the Fan
If all else fails, and you suspect a faulty fan motor, replacing the fan is the most practical solution. PC fans are relatively inexpensive and easy to replace.
Conclusion
Addressing a non-spinning PC fan is crucial for maintaining your computer’s health. By following these steps, you can effectively troubleshoot the “ca ch sưa fan case ko quay” problem and prevent potential overheating issues. A well-functioning cooling system is essential for optimal performance and longevity of your PC.
