PC Fan Making Rattling Noise (Causes, Fixes) 

Is your PC fan making a rattling noise? This can be extremely annoying, not to mention potentially harmful to your computer if left unchecked. In this article, we’ll show you some of the most common causes of this issue and how to fix them. One of the most common reasons for a rattling fan is simply that it’s covered in dust.

Over time, dust can build up on the blades of your fan, causing it to spin less smoothly and eventually creating that dreaded rattling noise. Thankfully, this is an easy problem to fix. Simply open up your computer case and use a can of compressed air to blow away all the dust from your fan.

If you don’t have compressed air, you can also use a soft-bristled brush to gently remove the dust. Another common cause of rattling fans is a loose screw.

If a screw comes loose, it can fall onto the fan blades and cause them to rattle. Again, this is an easy problem to fix. Simply remove the loose screw and re-tighten it. You may need to use a bit of force to get it right, but be careful not to over-tighten as this could strip the threads. If your fan is still rattling after dusting it and tightening any loose screws,

it’s possible that the problem lies with the fan itself. In this case, you’ll need to replace the fan. Fortunately, fans are relatively inexpensive and easy to find.

You can purchase them online or at most computer stores. When replacing your fan, be sure to get one that is the same size and model as the one you’re replacing. Otherwise, it may not fit properly in your computer case and could cause additional problems. Installing a new fan is relatively simple.

Just remove the old fan (being careful not to damage any other components in the process) and then install the new one in its place. Be sure to use the proper screws and not over-tighten them. Once you’ve replaced the fan, make sure to dust out your computer case on a regular basis to prevent the problem from happening again.

A can of compressed air and a soft-bristled brush should do the trick. If you find that your PC fan is making a rattling noise, don’t panic. In most cases, the problem is easily fixable and won’t cause any damage to your computer. Just be sure to dust it out regularly and check for loose screws. If all else fails, you can always replace the fan entirely.

5. Check CPU Temps In BIOS 

1. Restart your computer and press the key that allows you to enter the BIOS. This key is usually F2, F10, F11, or Del.

2. Use the arrow keys to navigate to the “Hardware Monitor” or “PC Health” section of the BIOS.

3. Look for CPU temperature readings in this section. If they’re not displayed here, check the manual that came with your motherboard to see where they are displayed.

4. If your CPU temperature is too high, you may need to clean the fan or replace it.

5. If your CPU temperature is normal, the rattling noise may be coming from another component of your computer.

6. Check CPU Temps Via An External Program

If your CPU is running too hot, it can cause the fan to rattle. Check your CPU temperature using an external program like SpeedFan, CoreTemp, or RealTemp to make sure it isn’t overheating. If it is, take steps to cool down your CPU.

7. Clean The Fan Blades

Dust and dirt can build up on the fan blades and cause them to rattle. Use a can of compressed air to clean the blades and remove any dirt or dust.

8. Check The Fan For Physical Damage

If the fan blades are bent or damaged, they may cause the fan to rattle. Inspect the fan blades to see if they are bent or damaged in any way. If they are, you will need to replace the fan.

9. Make Sure The Fan Is Securely Attached

10. Replace The Fan

Sometimes, no matter how much you clean and troubleshoot, the fan may just be too old and needs to be replaced. If all else fails, replacing the fan is your best bet.

11. Malware Infection

One of the most common reasons for a computer fan to start rattling is a malware infection. Over time, as more and more files become corrupted, the fan has to work harder to keep the system cool, which can lead to increased noise. If you suspect that your computer may be infected with malware, run a full scan with your anti-virus program. Dust Build-Up: Another common cause of rattling computer fans is dust build-up. Dust can enter the case through various openings, such as the fan grille, and eventually work its way into the fan blades. This can cause the fan to become unbalanced and start making noise.

To clean out the dust, you’ll need to open up your computer case and use a can of compressed air to blow it out. If you don’t feel comfortable doing this, you can take it to a computer repair shop and have them do it for you. Loose Screws: If your computer fan is attached to the case with screws, it’s possible that one or more of them may have become loose over time.

This can cause the fan to vibrate and make noise. To fix this, simply remove the fan and tighten the screws. If they’re too tight, you can use a drop of thread locker to keep them in place. Failing Bearing: If your computer fan is making a grinding noise, it’s possible that the bearing has failed. This is usually caused by dust build-up, which prevents the fan from spinning smoothly.

To fix this, you’ll need to replace the fan. You can do this yourself or take it to a computer repair shop. There are several things that can cause a computer fan to start rattling. The most common causes are malware infections, dust build-up, and loose screws. If your computer fan is making noise, you can try cleaning it out or replacing it. If the noise persists, you may need to take it to a computer repair shop.

12.No Breathability

The rattling noise might be caused by the fan blades being close to something else in the computer, such as the side of the case or another component. If this is the case, you can try to move the fan away from whatever it’s touching.

This might require opening up your computer case (be sure to discharge any static electricity first) and/or moving other components around. Another possibility is that the fan isn’t getting enough airflow, which can cause it to rattle.

Make sure there isn’t any dust buildup or obstructions around the fan, and consider adding more case fans if your computer doesn’t have very good airflow. If you’ve tried all of these things and the fan still rattles, it’s possible that the bearings in the fan are going bad. In this case, you’ll need to replace the fan. If your computer’s fan is rattling, there are a few possible causes.

The fan might be touching something else in the computer, or it might not get enough airflow. You can try to fix the problem by moving the fan or adding more case fans, but if the fan’s bearings are going bad, you’ll need to replace it.

How To Diagnose The Defective Fan

The most common way to find out if your computer’s fan is defective is to simply listen to it. If you hear a rattling noise, then it is likely that the fan blades are hitting something inside the housing. If the noise is coming from the back of the computer, then it is likely that the fan is not properly secured to the case. In some cases, you may be able to stop the noise by simply opening up the case and securing the fan.

However, if the noise persists, then you will likely need to replace the fan. Another way to diagnose a defective fan is to check the airflow from the fan. If the airflow is obstructed, then it is likely that the fan is not working properly. You can check the airflow by holding a piece of paper up to the fan.

If the paper does not move, the fan is not working properly. If you suspect that your computer’s fan is defective, then you should take it to a qualified technician for further diagnosis.

How To Prevent A Computer Fan From Rattling

There are several things that you can do to prevent your computer’s fan from rattling. The first thing you can do is ensure that the fan is properly secured to the case. You can also try to clean the fan blades with a soft cloth.

If the fan is still rattling, then you may need to replace it. Another way to prevent your computer’s fan from rattling is to avoid using it in dusty environments. If the fan is constantly exposed to dust, then the blades will eventually become clogged.

This can cause the fan to rattle. You can avoid this problem by keeping the fan clean and dust-free. If you are still having problems with your computer’s fan, then you should take it to a qualified technician for further diagnosis.
