Understanding Error 0135 CPU Fan Failure: Causes and Solutions

If you're a computer enthusiast or a professional who works with computers, you may have encountered Error 0135 CPU Fan Failure at some point. This error message typically appears during the boot process and indicates that the computer's CPU fan is not functioning correctly or is completely non-operational. As the CPU fan plays a crucial role in maintaining the temperature and preventing the CPU from overheating, this error must be addressed promptly to avoid potential damage to the system.

Causes of Error 0135 CPU Fan Failure

There are several possible causes for Error 0135 CPU Fan Failure. Let's explore some of the most common ones:

1. Malfunctioning Fan

The primary cause of Error 0135 CPU Fan Failure is a malfunctioning CPU fan. The fan may have worn out over time, leading to reduced performance or complete failure. Dust accumulation can also hinder the proper functioning of the fan, causing it to become noisy or eventually stop working altogether. Additionally, physical damage to the fan blades or the motor can result in fan failure.

If you suspect that a malfunctioning fan is causing the error, it is crucial to inspect and evaluate the fan's condition. Check for physical damage, excessive dust buildup, or any other issues that might be obstructing its operation. In some cases, simply cleaning the fan or replacing it with a new one may resolve the problem.

However, it's essential to ensure that the issue lies with the fan itself and not with the motherboard or other related components. Inspect the fan's connection to the motherboard and ensure it is securely plugged in. If the connection seems fine, you may want to explore other potential causes before concluding that the fan is the sole culprit.

2. Faulty Fan Control Settings

In some cases, Error 0135 CPU Fan Failure can be attributed to faulty fan control settings in the computer's BIOS (Basic Input/Output System). BIOS is responsible for managing various hardware components, including the CPU fan. If the fan control settings are not configured correctly or if they are set too low, the system may not detect the fan's operation properly, resulting in the error message.

If you encounter this error, entering the BIOS setup and adjusting the fan control settings may resolve the issue. Look for options related to fan speed or fan control and ensure that they are set to an appropriate level. However, exercise caution while making changes in the BIOS, as improper settings can potentially harm the system's stability or performance.

Refer to the motherboard's documentation or the manufacturer's website for specific instructions on accessing and modifying the BIOS settings. It is also a good idea to check for any available BIOS updates from the manufacturer, as these updates often address known issues and improve system compatibility.

3. Incorrect Fan Connection

An incorrect connection between the CPU fan and the motherboard can also trigger Error 0135 CPU Fan Failure. If the fan is not properly connected or if the connection is loose, the computer may not detect the fan's presence or receive accurate readings from it.

Ensure that the CPU fan is securely connected to the appropriate fan header on the motherboard. Disconnecting and reconnecting the fan, while ensuring a snug and secure connection, may help resolve the issue. Additionally, check for any bent or damaged pins on the fan header and straighten them if necessary.

If you've recently made any changes to your computer's hardware configuration, such as installing a new CPU cooler or upgrading the motherboard, double-check that the fan is compatible with your system and connected correctly.

4. BIOS or Firmware Update Needed

In some instances, Error 0135 CPU Fan Failure may indicate the need for a BIOS update or firmware update for the motherboard. Outdated BIOS or firmware versions can contain bugs or compatibility issues that affect the detection and functioning of the CPU fan.

Visit the manufacturer's website and check for any available updates for your motherboard model. Follow the provided instructions to perform the update carefully. Keep in mind that updating the BIOS or firmware can be a potentially risky process, so it's important to follow the instructions precisely and ensure that your system is stable before proceeding.

Resolving Error 0135 CPU Fan Failure

When encountering Error 0135 CPU Fan Failure, it is essential to address the issue promptly to prevent potential damage to your computer. Here are some steps you can take to resolve the error:

1. Clean the Fan and System

If dust accumulation is preventing the CPU fan from functioning correctly, cleaning the fan and the system can often resolve the issue. Use compressed air or a soft brush to remove any dust or debris from the fan blades, heatsink, and other components. Ensure that the computer is powered off and unplugged before attempting to clean it.

2. Check and Secure Fan Connections

Verify that the CPU fan is securely connected to the motherboard and that there are no loose or damaged connections. Disconnect and reconnect the fan if necessary, ensuring a tight and secure connection. Verify that the fan is compatible with your system and that it is properly installed according to the manufacturer's instructions.

3. Adjust BIOS Fan Control Settings

Access the BIOS setup and check the fan control settings. Adjust the settings to an appropriate level if they are too low or incorrectly configured. Refer to the motherboard's documentation or the manufacturer's website for instructions on accessing and modifying the BIOS settings.

4. Update BIOS or Firmware

If the previous steps did not resolve the error, consider updating the BIOS or firmware for your motherboard. Check the manufacturer's website for any available updates and follow the provided instructions carefully to perform the update. Ensure that your system is stable before proceeding with the update.

By following these steps and addressing the potential causes of Error 0135 CPU Fan Failure, you can resolve the issue and ensure the proper functioning of your computer's cooling system. Remember to handle all components with care and prioritize safety while troubleshooting or making any changes to your system.
