Introduction
This manual provides instructions for the installation, operation, and maintenance of your Generic Replacement Mini PC CPU Fan, designed for NiPoGi GK3 PRO systems. Please read this manual carefully before installation and use.
Important Compatibility Information
Critical Note: CPU fans, especially for mini PCs, often have specific wiring sequences for their connectors. Even if the connector physically fits, an incorrect wire sequence can lead to malfunction or damage to your device.
Before Installation: It is essential to verify that the wiring sequence of this replacement fan matches your original fan.
To ensure compatibility, please compare the pin configuration and wire colors of your original fan's connector with the images provided below. If you are unsure, it is recommended to consult with a qualified technician or the product supplier before proceeding with installation.

Setup and Installation
Disclaimer: Installing internal computer components requires careful handling and basic technical knowledge. If you are not comfortable performing this procedure, seek professional assistance.
Required Tools:
- Small Phillips head screwdriver
- Anti-static wrist strap (recommended)
- Thermal paste (if replacing CPU cooler, not just fan)
Installation Steps:
- Power Off: Completely shut down your Mini PC and disconnect all power cables and peripherals.
- Open Case: Carefully open the Mini PC's casing to access the internal components. Refer to your Mini PC's specific manual for case opening instructions.
- Locate Old Fan: Identify the existing CPU fan.
- Disconnect Old Fan: Gently disconnect the old fan's power cable from the motherboard. Note the orientation and wiring sequence.
- Remove Old Fan: Unscrew and remove the old fan.
- Clean Area: If necessary, clean any dust from the heatsink and surrounding area.
- Install New Fan: Position the new replacement fan over the heatsink, ensuring proper alignment. Secure it with screws.
- Connect New Fan: Carefully connect the new fan's 4-pin connector to the corresponding header on the motherboard. Double-check the wiring sequence against your original fan and the compatibility notes.
- Close Case: Reassemble the Mini PC's casing.
- Power On: Reconnect power and peripherals, then power on the Mini PC.
Operation
The CPU fan operates automatically, controlled by the Mini PC's BIOS/UEFI and operating system to maintain optimal CPU temperatures.
Upon startup, the fan should spin. Its speed will adjust based on the CPU's workload and temperature.
Maintenance
Dust Removal:
Regularly inspect the fan and heatsink for dust accumulation. Dust can impede airflow and reduce cooling efficiency.
Use compressed air or a soft brush to gently remove dust from the fan blades and heatsink fins. Ensure the fan blades are held stationary while using compressed air to prevent over-spinning and potential damage.
Inspection:
Periodically check for any unusual noises or vibrations from the fan, which could indicate a bearing issue or obstruction.
Troubleshooting
Fan Not Spinning:
- Check Connection: Ensure the fan's 4-pin connector is securely seated on the motherboard header.
- Compatibility: Re-verify the wiring sequence compatibility as highlighted in the Important Compatibility Information section. An incompatible fan may not receive power correctly.
- BIOS Settings: Check BIOS/UEFI settings for fan control options. Ensure fan headers are enabled and not set to a passive mode at low temperatures.
- Obstruction: Ensure no cables or debris are blocking the fan blades.
Excessive Noise:
- Dust: Clean the fan and heatsink thoroughly.
- Loose Screws: Ensure the fan is securely mounted and screws are tightened.
- Obstruction: Check for any cables or objects touching the fan blades.
- Bearing Issue: If the noise persists and is a grinding or rattling sound, the fan bearings may be faulty. Consider replacement.
Overheating:
- Fan Function: Confirm the fan is spinning correctly.
- Airflow: Ensure proper airflow within the Mini PC case.
- Thermal Paste: If the heatsink was removed during installation, ensure new thermal paste was applied correctly.
- Compatibility: An incompatible fan might not provide adequate cooling even if spinning.
