What happens to your PC when its case fans stop spinning? Well, this can cause serious problems and you need to take care of it unless all insides are damaged. They can have a huge impact on thermals – so much – to the point that you risk all-out system failure.
The PC’s case fans are there to cool down the whole system, in case they stop spinning due to any reason, there is a great danger that your CPU, hard drives, and motherboard are damaged as well.
A case fan helps to maintain the airflow inside your PC. It helps to remove the hot air produced inside the system and maintain the cool temperature for all these devices. If your system is getting heated up more than normal, you should check if your case fan is spinning or not, in worst cases, if you did not take care of the problem at hand immediately, your PC might not get started or it will be started and shut down immediately.
How Many Case Fans Do You Need?
Normally you need at least two of the case fans on your system. The front fan and the back fan. Now, the front fan is to bring the cool air inside of the system, and the back fan work as an exhaust fan that exhales out the hot air.
When you turn on your PC, these fans start working with the voltage provided into the system and this cycle of airflow helps to maintain the cool temperature, which your device needs.

The case fan is not spinning – Possible Reasons
This can happen due to a number of reasons and we have tried to list down all of them. We will briefly discuss here the reasons why this happens.
Voltage Supply Issue
Your fans take a bit of voltage in order to run properly. When you start your device, sometimes due to a current breakdown or electric issue you might face this issue. Make sure your electricity is okay and when you start your computer, it runs smoothly.
Cleanliness is the key to success
Cleanliness of different parts of all your electronic devices is a necessity. When for a long time you do not give a thought to cleaning up your devices, dirt may stuck there, just like our homes. Due to the dirt issue, you may also face this problem, which is rare but it is possible.
Fan’s itself issue:
Well, they are electronic devices and if they get stuck or damaged sometimes it is totally understandable. Make sure you check if your computer fans are damaged or not. If there is a fan’s hard drive issue, you might need to replace it.
The chances of possibility that there is a connectivity issue, which you might be facing right now, are high. The case fans need a connection with the system in order to work and they are connected with a two-pin or four-pin configuration with your motherboard.
In some cases, the fan cases are connected with PSU that supplies power to them. You need to make sure that all the wires are connected in their slots and there are no problems with the connectivity.
BIOS at Fault
BIOS is responsible to run any device smoothly. If there is an error here then you might be facing a similar error with your case fans. However, this issue can be resolved very easily. So, no need to worry much about it.
The case fan not spinning – Possible Solutions
As we have now know what might be the cause of your fan case not spinning, you can try out these methods to check which applies to your problem.
The very basic step to solve most of the temporary errors on any system is to restart your device. The voltage required to run the fans is very low and therefore if there is dust or any other external particle is stuck in your system, so in order to get rid of this temporary issue, restarting your device might solve the issue.
- You need to turn off your device completely and remove all connections from the main switch as well
- You need to annihilate any power static energy, so press and hold your CPU power button for more than 20 seconds
- Make sure you do this while your connections are not attached to your device
- Once it’s done, leave the power button and try reconnecting the main connection
- Now again restart your computer and check if the issue has been resolved
If this is only a static or unstable power connectivity issue, this method will resolve it completely.
Clean the Area
As we mentioned earlier, cleanliness might be an issue here. You need to make sure that your device’s fans are dust-free and there is nothing stuck in them that is causing a case fan not working issue in your device.
Now, you need to remember that this is not like your room fan, which you clean easily, you will have to remove case fans from the CPU, and then you will have to clean them very carefully. You will need to remove the screws, get the fan out, clean it thoroughly, and after that place it back. There might also be something that was stuck in the fans and as the voltage is not very high; your fans cannot get it done by themselves. So here, you need to help them and check besides dust is there anything stuck in the fans.
In any case, you will be required to open the fan case and remove the issue at hand. It is highly recommended that you seek a professional’s help but in case you are good with computers, you can try it out at home too. You can also grab some air cleaning products available in the market and they will do the job well. You will need to restart your device once you are done with the cleaning process
Sometimes if an error related to any device occurs in the BIOS, that specific application or device will stop working. You can troubleshoot your BIOS again check if it works out for you. We will guide you in detailed steps on how to configure BIOS:
- In order to go to the BIOS setting, you always need to turn off your device completely
- Now, after a few seconds, restart by turning the power on and keep pressing the F2 key more than a few times until you see the BIOS configuration system on your screen. (the function key we are using here is F2 which works for most devices but it is highly possible that your device’s BIOS key is different, so do the math’s beforehand and figure out which BIOS function key works on your computer)
- Now you need to go to the default settings for the reset
- You can easily find these settings on the screen but in case you are stuck here, press the F9 key and it will take you directly to the ‘Load setup default’ settings
- Click on the settings and then exit the window
Pro Tip: you can use cursor keys on your keyboard to navigate in the BIOS system and press the enter button to select the settings or options.
Replacement of the Hard Drive
If there was nothing wrong with your BIOS system, surely the issue lies within either your motherboard, PSU, or the fan itself. You will need to figure out which one among them is having an issue and try to resolve it according to by replacing that specific hard drive with the new one.
It is highly recommended that do not replace the hard drives on your own at home and take the help of a professional.
