3. Installation Guide
This section provides general steps for installing the Aigo AC SE 240 Water Cooler. Refer to your motherboard and PC case manuals for specific instructions regarding component placement and cable management.
3.1 Prepare the CPU and Motherboard
- Ensure your system is powered off and disconnected from the power source.
- Remove any existing CPU cooler. Clean the CPU surface thoroughly with isopropyl alcohol to remove old thermal paste.
- Identify the correct mounting bracket for your CPU socket (Intel or AMD).
3.2 Install the Radiator and Fans

- Attach the two 120mm fans to the radiator using the provided long screws. Ensure the fan airflow direction is correct for your case (typically intake or exhaust).
- Mount the radiator assembly to an available 240mm fan mount in your PC case (e.g., top, front, or rear). Use the appropriate screws to secure it.
3.3 Install the CPU Block/Pump
- Apply a small amount of thermal paste to the center of your CPU's integrated heat spreader (IHS). A pea-sized dot is usually sufficient.
- Attach the correct mounting standoffs and brackets to your motherboard around the CPU socket. For Intel sockets, you may need to install the backplate first.
- Carefully place the CPU block/pump onto the CPU, aligning the mounting holes.
- Secure the CPU block/pump with the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.
3.4 Connect Cables
- Connect the pump's power cable to a dedicated AIO_PUMP or CPU_FAN header on your motherboard. If neither is available, use a SYS_FAN header.
- Connect the fan power cables to the CPU_FAN and/or SYS_FAN headers on your motherboard, or to the included fan/RGB controller.
- Connect the RGB cables from the fans and pump to the included RGB controller, and then connect the controller to an available RGB header on your motherboard (if applicable) or a SATA power connector.
- Organize cables for optimal airflow and aesthetics.
4. Operating Instructions
Once installed, the Aigo AC SE 240 Water Cooler operates automatically. The pump and fans will adjust their speeds based on CPU temperature, as controlled by your motherboard's BIOS/UEFI settings or dedicated software.
- BIOS/UEFI Settings: Access your motherboard's BIOS/UEFI to configure fan curves and pump speed settings. It is recommended to set the pump to run at 100% speed for optimal cooling performance and to prevent air bubbles from settling.
- Software Control: If your motherboard supports it, you may use manufacturer-provided software to fine-tune fan speeds, monitor temperatures, and customize RGB lighting effects.
- Initial Startup: During the first few minutes of operation, you might hear gurgling sounds as air bubbles are purged from the loop. This is normal and should subside.

5. Maintenance
Regular maintenance ensures optimal performance and longevity of your water cooler.
- Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Excessive dust can impede airflow and reduce cooling efficiency.
- Tubing Inspection: Visually inspect the tubing and connections for any signs of leaks, kinks, or damage. Address any issues immediately.
- Pump Noise: If the pump starts making unusual noises, it may indicate air trapped in the loop or a failing pump. Ensure the pump is running at full speed and try gently tilting your PC case to help dislodge air bubbles.
