Removing a plastic fan from a PC typically involves the following steps: ensuring the PC is turned off, locating and disconnecting the fan's power cable from the motherboard, and then unscrewing or unclipping the fan from the case. Some older or cheaper fans may have plastic or rubber stoppers that can be removed, but modern fans are often designed without removable parts to prevent issues with gunk or lubricant. When disassembling a fan, it's important to be cautious and use appropriate tools like tweezers or thin knives to avoid damage.

What You'll Learn
Unplug the fan from the motherboard or power supply
To unplug the fan from the motherboard or power supply, you must first ensure the computer is switched off. It is also important to be aware of ESD (Electrostatic Discharge) and its dangers.
The fan will be connected to the motherboard via a two, three, or four-pin power cable. Locate this cable and disconnect it by pulling on the connector end, not the wire. Pulling on the wire may loosen it from the connector. If the connector is glued, use a small flat screwdriver to gently pry it open at the corners.
With the fan unplugged, it can now be removed from the computer. Case fans are usually screwed into the case or have small clips that can be pressed or pulled.
If you are removing a case fan to clean it, you can take it apart to access the fan blades. You can then soak, clean, and wash the blades, and oil the bearings and motor assembly. Be aware that smaller fans, such as those found on GPUs, are harder to remove as you have to pull off a plastic ring to access the fan blades.

Remove the plastic ring from the fan's axle
Before attempting to remove the plastic ring from the fan's axle, it is important to ensure that your PC is switched off and unplugged from the power source. Familiarise yourself with the dangers of Electrostatic Discharge (ESD) before proceeding.
The plastic ring on the fan's axle can be removed in several ways, depending on the fan's make and model. Firstly, identify the type of fan you have and the method used to secure the fan to the axle. Some common methods include set screws, clamps, snap rings, or built-in plastic tabs.
If your fan uses a set screw, locate the screw and use the appropriate tool to loosen and remove it. If the screw is an Allen screw, you will need an Allen key. If it is a standard slot screw, a flat-head screwdriver should do the trick. Once the screw is removed, you can slide out the fan.
For fans secured with a snap ring, use a pair of tweezers or the tip of a thin pocket knife to carefully remove the ring. Ensure you do not break the ring, as you will need it when reassembling the fan.
If your fan has a built-in plastic tab, insert a thin strip of metal into the tab to release the fan. You can then pry out the fan, being careful not to damage it.
In some cases, you may need to use a letter opener, knife, or flat-head screwdriver to gently pry or pop the fan off the axle. This method may require some force, but be careful not to damage the fan or any other components.
Additionally, some fans may have left-hand threads, meaning you need to spin the cap in the opposite direction of a typical unscrewing motion.
Always refer to the manufacturer's instructions or seek guidance from a professional if you are unsure about any steps in the removal process.

Use tweezers or a knife to carefully lift the ring
When removing a case fan from a computer, it is important to first ensure that the computer is switched off and unplugged. You should also be aware of the potential dangers of ESD (Electrostatic Discharge). Before the fan can be removed, it must be unplugged from the motherboard or its power source.
Now, to carefully lift the ring using tweezers or a knife:
Firstly, identify the type of fan you are working with. Some fans have an outer ring, which means you cannot simply use your thumbs to remove the fan. Brushless fans, for example, need to be pushed out from the back, and they have an outer ring. You will need to get the inner ring to remove this type of fan.
If your fan has a plastic ring, you can use a pair of tweezers or the tip of a thin pocket knife to carefully lift and remove it. Be cautious not to break the ring, as you will need to put it back on later when reassembling the fan. Some case fans have metal clasps instead of plastic, so be mindful of this when starting the removal process.
Alternatively, you can use two knives to carefully lift the ring. Wedge two flathead screwdrivers or knives under the center portion of the fan shaft and gently twist to pop the ring off.
If you are working with a Gentle Typhoon Ball Bearings PC fan, you will need to remove the back label to access the external metal c-clip on the fan shaft. Use a heat gun or hair dryer on a high setting to heat up the label and then use tweezers to carefully peel it off. Stick the label onto a clean metal surface to keep it safe while you work.
To remove the metal c-clip, hold it in a retaining ring plier and widen the jaw. Then, use a needle-nose plier to compress the jaw of the c-clip. This process will allow you to reuse the metal c-clip when reassembling the fan.

Disconnect the power cable by pulling on the connector end
Disconnecting the power cable by pulling on the connector end is a crucial step in removing a plastic fan from your PC. This step ensures that the fan is completely disconnected from its power source before you proceed with the physical removal. Here's a detailed guide on how to do this safely and effectively:
Locate the Power Cable: Start by identifying the power cable that connects your plastic fan to the motherboard. This is typically a two-, three-, or four-pin power cable. It may be labelled as PWR_FAN, as shown in some examples.
Grab the Connector End: Once you've located the power cable, focus on the connector end. This is the end of the cable that plugs into the motherboard or the fan itself. Grabbing the connector end is crucial to ensure a proper disconnection. Avoid pulling the cable by the wire, as it may loosen the connection.
Pull Up on the Connector: Now, gently pull up on the connector. Apply a gentle upward force to detach the connector from its port. Be careful not to pull too hard, as you don't want to damage the connector or the motherboard. A firm but controlled pull should be sufficient.
Confirm Disconnection: After pulling on the connector, verify that the cable is no longer connected to the motherboard or the fan. This step is important to ensure that the power supply to the fan is completely interrupted before proceeding further.
Prepare for Next Steps: With the power cable successfully disconnected, you can now focus on the physical removal of the fan. Depending on your PC's configuration, the fan may be screwed into the case or held in place with small clips. Be prepared to either unscrew the fan or locate and manipulate the clips for the next steps.
Safety Precautions: Always exercise caution when working inside your computer. Ensure that the PC is turned off before beginning any disassembly process. Familiarize yourself with electrostatic discharge (ESD) and its potential dangers to avoid accidental damage to your computer components.
By following these steps, you can safely disconnect the power cable by pulling on the connector end. This sets the stage for the next steps in removing the plastic fan from your PC, whether it's for cleaning, replacement, or other maintenance tasks. Remember to be gentle and deliberate in your actions to avoid any accidental damage to your computer's internal components.
