Installation Guide
The TEUCER AF-S Series cooler is designed for simple and quick installation. Ensure your system is powered off and unplugged before proceeding.
1. Prepare Your Motherboard and CPU
- Identify your CPU socket type (Intel LGA or AMD AM).
- Install the appropriate backplate (if required by your socket) and mounting standoffs onto your motherboard.
- Clean the CPU surface with isopropyl alcohol to remove any old thermal paste.
2. Install the Radiator and Fans
- Attach the AF-12025 RGB fans to the radiator using the provided long screws. Ensure the fan airflow direction is as desired (typically pushing air through the radiator and out of the case, or pulling air in).
- Mount the radiator assembly to an available fan mount location in your PC case (e.g., top, front, or rear). Use the appropriate screws to secure it.
3. Mount the Pump Head
- Apply a small amount of thermal paste (pea-sized dot) to the center of your CPU's integrated heat spreader (IHS).
- Attach the correct mounting bracket for your CPU socket to the pump head.
- Carefully place the pump head onto the CPU, aligning the mounting holes with the standoffs.
- Secure the pump head with the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.

4. Connect Cables
- Connect the pump's 3-pin or 4-pin power cable to the CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the fan power cables (3-pin or 4-pin) to available fan headers on your motherboard, or use the provided splitter cable to connect multiple fans to a single header.
- Connect the RGB cables from the fans and pump head to your motherboard's Addressable RGB (ARGB) header (typically 3-pin, 5V) or to a dedicated RGB controller. Ensure correct voltage (5V ARGB, not 12V RGB) to prevent damage.
The installation process is designed to be straightforward, providing reliable heat dissipation while minimizing noise interference.
Operation
Power On and Initial Check
- After installation, double-check all connections.
- Power on your PC. The fans and pump should start operating, and the RGB lighting should illuminate.
- Monitor CPU temperatures using system monitoring software to ensure proper cooling.
RGB Lighting Control
The TEUCER AF-S Series features colorful RGB lighting effects on both the fans and the pump head. These can be controlled via your motherboard's RGB synchronization software (e.g., ASUS Aura Sync, GIGABYTE RGB Fusion 2.0, MSI Mystic Light Sync, ASRock Polychrome RGB) if connected to an ARGB header. Alternatively, if connected to a dedicated controller (not included), use the controller's software or physical buttons to adjust lighting modes and colors.

Fan and Pump Speed Control
Fan and pump speeds are typically controlled by your motherboard's BIOS/UEFI settings or through motherboard-specific software. You can set custom fan curves to balance cooling performance and noise levels according to your preferences.
Maintenance
Regular maintenance helps ensure optimal performance and longevity of your liquid cooler.
- Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Dust buildup can impede airflow and reduce cooling efficiency.
- Tube Inspection: Check the FEP polymer water cooling tubes for any signs of kinks, leaks, or damage. The reinforced woven mesh bushing provides protection against wear and tear.
- Pump Head: Ensure the pump head remains securely mounted to the CPU.
- Coolant: As an AIO (All-In-One) unit, the cooler is pre-filled and sealed. No user maintenance of the coolant is required. Do not attempt to open the loop.
Troubleshooting
If you encounter issues with your TEUCER AF-S Series liquid cooler, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| High CPU Temperatures |
|
|
| RGB Lighting Not Working |
|
|
| Loud Fan/Pump Noise |
|

User Tips
- For optimal cooling performance, ensure your PC case has good airflow and that the radiator fans are configured to either push hot air out of the case or pull cool air in, depending on your case's thermal design.
- When installing the radiator, try to position it so that the tubes are at the bottom of the radiator. This helps prevent air bubbles from accumulating in the pump, which can cause noise and reduce pump lifespan.
- Experiment with different fan curve settings in your motherboard's BIOS to find the best balance between cooling efficiency and acoustic comfort for your specific system and workload.
- Regularly check for firmware updates for your motherboard, as these can sometimes improve compatibility and control over RGB lighting and fan speeds.
