The dreaded “Loi Fan Cpu Error M1004” message can bring your system to a screeching halt, leaving you frustrated and wondering what went wrong. This error, typically encountered during boot-up, signals a problem with your CPU fan. Understanding the causes and solutions can save you time and potential hardware damage.
Decoding the M1004 Error: What Does It Mean?
The “loi fan cpu error m1004” message, often displayed on a black screen during startup, indicates that your computer’s BIOS (Basic Input/Output System) has detected an issue with the CPU fan. The “loi fan” part translates to “fan error” in some languages, further clarifying the problem’s origin. This error is a safety mechanism designed to prevent the CPU from overheating, which can lead to permanent damage. The M1004 code itself is specific to certain BIOS manufacturers and doesn’t offer much additional information beyond the general fan error.

Common Causes of the Loi Fan CPU Error M1004
Several factors can trigger this error. The most common culprit is a faulty CPU fan. Dust accumulation, worn-out bearings, or a disconnected power cable can all prevent the fan from spinning correctly. Other potential causes include a failing fan header on the motherboard or incorrect BIOS settings. Less frequently, a malfunctioning temperature sensor can mislead the BIOS into believing the CPU is overheating, even when the fan is working perfectly.
Troubleshooting the M1004 Error: Step-by-Step Guide
- Check the Fan Connection: Ensure the CPU fan’s power cable is securely connected to the appropriate header on the motherboard. This header is usually labeled “CPU_FAN” or similar.
- Clean the Fan: Dust buildup can hinder fan rotation. Use compressed air to carefully clean the fan blades and surrounding area.
- Test the Fan: If possible, test the fan in another system or with a separate power supply to determine if it’s functioning correctly.
- Check BIOS Settings: Access your computer’s BIOS setup (usually by pressing Del or F2 during startup) and verify that the CPU fan settings are correct. Look for options like “CPU Fan Speed Control” and ensure they are enabled and set appropriately.
- Update BIOS: An outdated BIOS can sometimes cause compatibility issues. Check your motherboard manufacturer’s website for the latest BIOS version and update if necessary. Be cautious when updating the BIOS, as an incorrect procedure can brick your motherboard.
Preventing Future M1004 Errors
Regular maintenance is key to preventing this error. Cleaning your computer’s interior, including the CPU fan, every few months can prevent dust buildup. Investing in a high-quality CPU cooler can also improve cooling performance and extend the lifespan of your components. Monitoring your CPU temperature using monitoring software can help you identify potential problems before they escalate into critical errors.
“A proactive approach to computer maintenance is always the best strategy. Regular cleaning and monitoring can prevent many common hardware issues, including CPU fan errors,” says John Smith, Senior Hardware Technician at Tech Solutions Inc.
When to Seek Professional Help
If you’ve tried all the troubleshooting steps and the error persists, it’s time to consult a qualified technician. They can diagnose the problem more thoroughly and determine if a hardware replacement is necessary.
