Setup and Installation
Follow these steps carefully to replace your graphics card fan.
1. Disassembly of the Old Fan
- Power Off: Turn off the computer and shut down the machine completely.
- Open Case: Open the side panel of the computer case.
- Remove Graphics Card: Unscrew the PCIe cover screws and carefully pull the graphics card out horizontally.
- Disconnect Fan: Use tweezers to remove the fan connector plug. Pay close attention to the direction of the snap and avoid pulling forcefully.
- Remove Old Fan: Unscrew the fan fixing screws (typically 2-4 screws), then remove the old fan and the heat sink cover.
- Clean Heatsink: Clean any dust from the heat sink fins using a soft brush and compressed air, blowing outward from the gaps.
2. Installation of the New Fan
- Align Fan: Align the new fan with the screw holes on the heat dissipation module.
- Secure Fan: Screw in the fixing screws. Apply moderate force and ensure not to slip.
- Connect Fan: Align the fan connector with the fan interface on the graphics card PCB and insert the connector. A "click" sound indicates it is properly seated.
- Reassemble: Replace the graphics card, fix the PCIe cover, connect the power cable, and close the computer case.
- Power On Test: Power on the computer. The fan should rotate normally without stalling or abnormal noise.
Operating Instructions: Fan Speed Control
The fan speed can be controlled through various methods to balance temperature and noise.
1. 0dB Stop Mode (Default and Common)
- Trigger Conditions (Example for ASUS): Fan stops when GPU temperature is below 50°C and power consumption is below 50W, provided 0dB mode is enabled.
- Start Conditions: Fan automatically starts when GPU temperature exceeds 52-55°C or power consumption exceeds 100W.
- Disabling 0dB Mode: This can typically be turned off within the graphics card control software (e.g., GPU Tweak III, Adrenalin, NVIDIA Control Panel).
2. Software Speed Control (Recommended)
- NVIDIA Graphics Cards:
- Open the NVIDIA Control Panel.
- Navigate to Performance > Device settings > Fan control.
- Select manual fan control and drag the slider to set the speed (0-100%).
- Alternatively, use MSI Afterburner to set a custom fan curve based on temperature-speed correspondence and save the configuration.
- AMD Graphics Cards:
- Open AMD Adrenalin software.
- Navigate to Performance > Adjust > Fan > Advanced control.
- Enable manual speed control and set the base speed and temperature thresholds.
- During gaming or rendering, you may increase the speed (e.g., 50-70%) to balance temperature and noise.
- Asus/Micro-Star/Gigabyte and Other Brands: Utilize special software like GPU Tweak III, Dragon Center, or AORUS Engine to preset silent, performance, or game modes.
3. BIOS Speed Control (Advanced)
- Boot the computer and press Del/F2 (or equivalent key for your motherboard) to enter the motherboard BIOS.
- Navigate to Hardware monitoring > Graphics card fan control.
- Select PWM mode or voltage mode and set the temperature trigger point and speed.
- Caution: Beginners should use this method with caution to avoid improper settings that could lead to overheating.
Maintenance
Regular maintenance helps ensure the longevity and efficiency of your graphics cooler.
- Dust Cleaning: Periodically clean dust from the heat sink fins. Use a soft brush and compressed air to blow dust outward from the gaps of the fins. This should be done during the disassembly process or whenever you notice significant dust buildup.
Troubleshooting
Common Issues and Solutions:
- Fan Not Rotating or Abnormal Noise After Installation:
- Ensure the fan connector is securely and correctly plugged into the graphics card PCB.
- Verify that the fan fixing screws are not overtightened, which could cause binding.
- Check for any obstructions preventing the fan blades from rotating freely.
- Confirm that the graphics card is properly seated in its PCIe slot and receiving power.
- Overheating Issues:
- If using BIOS speed control, ensure settings are correct and not causing the fan to run too slowly. Incorrect BIOS settings can lead to overheating.
- Verify that the heatsink is clean and free of dust, as dust buildup significantly reduces cooling efficiency.
- Ensure proper airflow within your computer case.
User Tips
- Always double-check the physical dimensions and mounting hole distances of your existing fan against the replacement fan to ensure compatibility, as graphics card models can vary.
- Remember that this product is a fan replacement only; it typically does not include mounting screws or heatsinks. Reuse existing hardware or acquire compatible replacements if needed.
- When adjusting fan speeds via BIOS, proceed with caution. Incorrect settings can lead to insufficient cooling and potential hardware damage. Software-based fan control is generally recommended for beginners.
