A squeaky PSU (Power Supply Unit) fan can be a frustrating and annoying problem for computer users. Not only can it be distracting, but it can also be a sign of a more serious issue with your computer’s power supply. In this article, we will explore the causes of a squeaky PSU fan and provide a step-by-step guide on how to fix it.
Understanding the Causes of a Squeaky PSU Fan
Before we dive into the repair process, it’s essential to understand the causes of a squeaky PSU fan. There are several reasons why your PSU fan might be squeaking, including:
Wear and Tear
Over time, the fan bearings in your PSU can wear out, causing the fan to vibrate and produce a squeaking noise. This is a common problem in older computers, where the fan has been running continuously for years.
Dust and Dirt
Dust and dirt can accumulate on the fan blades and bearings, causing friction and vibration. This can lead to a squeaking noise, especially when the fan is running at high speeds.
Loose Screws or Mounts
If the screws or mounts that hold the fan in place are loose, it can cause the fan to vibrate and produce a squeaking noise.
Overheating
If your PSU is overheating, it can cause the fan to run faster and produce a squeaking noise.
Step-by-Step Guide to Fixing a Squeaky PSU Fan
Now that we’ve explored the causes of a squeaky PSU fan, let’s move on to the repair process. Here’s a step-by-step guide to fixing a squeaky PSU fan:
Step 1: Shut Down Your Computer
Before you start repairing your PSU fan, make sure to shut down your computer completely. Unplug the power cord and any other cables connected to the PSU.

Once you’ve removed the PSU from the case, disconnect the fan cable from the motherboard. This will prevent any accidental starts while you’re working on the fan.
Step 4: Remove the Fan Grill or Cover
To access the fan, you’ll need to remove the fan grill or cover. This is usually held in place by screws or clips. Use a screwdriver or pliers to remove the screws or clips.
Step 5: Clean the Fan Blades and Bearings
Use compressed air or a soft brush to clean the fan blades and bearings. This will remove any dust or dirt that may be causing the squeaking noise.
Step 6: Apply Lubricant to the Bearings
If the fan bearings are worn out, you may need to apply lubricant to reduce friction and vibration. Use a few drops of oil or silicone-based lubricant on the bearings.
Step 7: Reassemble the Fan and PSU
Once you’ve cleaned and lubricated the fan bearings, reassemble the fan and PSU. Make sure to reconnect the fan cable to the motherboard.
Step 8: Test the Fan
Turn on your computer and test the fan. If the squeaking noise is still present, you may need to replace the fan or PSU.
Replacing the PSU Fan
If cleaning and lubricating the fan bearings doesn’t fix the squeaking noise, you may need to replace the PSU fan. Here’s a step-by-step guide to replacing the PSU fan:

What causes a PSU fan to squeak?
A squeaky PSU fan is usually caused by worn-out or loose fan bearings. Over time, the bearings can deteriorate, causing the fan blades to vibrate and produce a squeaking noise. Additionally, dust buildup or misalignment of the fan blades can also contribute to the squeak.
In some cases, the squeak may be caused by a more serious issue, such as a failing fan motor or a malfunctioning fan controller. However, in most cases, the problem can be resolved by simply cleaning or replacing the fan bearings.
Do I need to replace the entire PSU if the fan is squeaky?
Not necessarily. If the squeak is caused by worn-out fan bearings or dust buildup, it’s possible to repair or replace the fan without replacing the entire PSU. However, if the squeak is caused by a more serious issue, such as a failing fan motor or a malfunctioning fan controller, it may be necessary to replace the entire PSU.
Before attempting to repair the fan, it’s essential to diagnose the problem and determine the cause of the squeak. If you’re not comfortable with DIY repairs or if you’re unsure about the cause of the problem, it’s recommended to consult a professional or contact the manufacturer for assistance.
What tools do I need to repair a squeaky PSU fan?
To repair a squeaky PSU fan, you’ll need a few basic tools, such as a screwdriver, pliers, and a can of compressed air. You may also need a replacement fan or fan bearings, depending on the cause of the problem.
It’s essential to use caution when working with electrical components, so make sure to unplug the PSU and ground yourself before starting the repair. Additionally, consult the PSU manual or online documentation for specific instructions and precautions.
Can I use a different type of fan to replace the original PSU fan?
It’s possible to use a different type of fan to replace the original PSU fan, but it’s essential to ensure that the replacement fan is compatible with the PSU. Check the PSU manual or online documentation for specifications and recommendations on replacement fans.
When selecting a replacement fan, consider factors such as fan speed, noise level, and airflow. Make sure the replacement fan is designed for use in a PSU and can handle the same voltage and current as the original fan.
How do I prevent my PSU fan from squeaking in the future?
To prevent your PSU fan from squeaking in the future, make sure to clean the fan regularly using compressed air. Additionally, ensure that the PSU is installed in a well-ventilated area to prevent dust buildup.
It’s also essential to monitor the PSU fan’s performance and address any issues promptly. If you notice any unusual noises or vibrations, shut down the system and inspect the fan. Regular maintenance can help extend the lifespan of the PSU fan and prevent squeaks.
Is it safe to repair a squeaky PSU fan myself?
Repairing a squeaky PSU fan can be safe if you follow proper precautions and guidelines. However, if you’re not comfortable with DIY repairs or if you’re unsure about the cause of the problem, it’s recommended to consult a professional or contact the manufacturer for assistance.
