PC gaming is a huge market, but it’s not as big as consoles. So what can PC gamers do to make their platform more attractive?

The cpu fan spins then stops repeatedly is a problem that has been present for a while. This article will show you 5 ways to fix the issue.

There’s no need to worry if one of your PC fans suddenly stops spinning; it’s a fairly frequent issue that most PC builders will face at some time. There are a lot of PC fan manufacturers who offer a variety of cooling chassis fans, and nearly all of them use the same mechanism.


There are now many discussions on the internet where many people are claiming that their fans have suddenly stopped spinning. As a result, we’re here to assist you with some simple techniques that will help you save time and effort in finding a suitable solution to the problem.

Step 1: Find a source of power for your fans.

As I already said, most contemporary fans need two separate power sources to function correctly. One is for RGB lighting, while the other is for providing power to the fan. As a result, the first step will be to double-check that the fan header on the motherboard to which you have connected the fan is in good working order.

If you’re using a fan hub, though, be sure the power supply for the fan header is correctly connected.

Step 2: Adjusting the Fan Voltage

After you’ve completed Step 1, check to see whether the voltage supply is functioning correctly, since the fans will need 12 volts to operate properly. If your motherboard is delivering a lower voltage, you’ll need to adjust the BIOS to correct the problem.

Check the BIOS settings to verify that your motherboard’s fan headers are enabled and set to auto.

Step 3: Restart and wait for the message to arrive.

If both of the above procedures fail to assist, you should do a thorough examination of the fans to verify that they are in good working order. Simply restart your computer and see if the fans are whirling or not after it has reached POST. This is due to the fact that when you just turn on your computer, the MB controller turns on all 12v/100% fan power. This implies that if your fans are operating here, they are OK, and you should double-check each connector for correct connection.

Step 4: What Should You Do If Your Fan Header Fails?

You may be trapped with the fans because you don’t have enough fan headers when your current fan headers stop functioning and you discover that the fan works properly when attached to another header. You can either buy a fan hub or a converter to link them with SATA connections if you don’t want to spend the money on a hub right now.

Step 5: The Life of Fan Bearings

If you’ve been operating that system with all of the fans for a long time and they suddenly cease functioning, you should take a closer look at them before drawing any conclusions. It’s possible that the bearings on those fans were clogged, causing the fans to cease rotating. In such case, be sure to clean the fans thoroughly, particularly the bearings, and then double-check once they’ve been well cleaned. There are four different kinds of fan bearings available on the market.

To sum it up

If the following methods fail to resolve the problem, you should consult a service center to verify that the fans are in good working order. If they are under warranty, you can always obtain a replacement. However, it is critical to keep a careful eye on the appropriate voltage and RPM of the fans.
