Setup and Installation
Before beginning installation, ensure your system is powered off and unplugged. Refer to your motherboard manual for specific CPU socket information.
General Installation Steps:
- Prepare CPU Socket:
- For Intel LGA1700/1200/115X: Install the appropriate backplate behind the motherboard. Secure it with the correct standoffs.
- For AMD AM5/AM4: Utilize the original AMD backplate that comes with your motherboard. Install the AMD-specific standoffs.
- Apply Thermal Paste: Apply a small, pea-sized amount of thermal paste to the center of your CPU's Integrated Heat Spreader (IHS).
- Mount Water Block/Pump: Carefully place the water block onto the CPU, aligning the mounting holes with the standoffs. Secure it with the provided thumb screws or nuts, tightening in a diagonal pattern until snug.
- Install Fans on Radiator: Attach the three 120mm ARGB fans to the radiator using the long screws provided. Ensure the fan airflow direction is appropriate for your case (typically blowing air through the radiator and out of the case, or into the case for intake).
- Mount Radiator: Install the radiator assembly into your PC case. Common mounting locations include the top or front of the case, depending on available space and case design. Secure it with the appropriate screws.
- Connect Cables: Refer to the wiring diagram below for proper connections.

Cable Connections Summary:
- Pump: Connect the 3-pin pump cable to your motherboard's CPU_FAN or AIO_PUMP header.
- Fans: Connect each 4-pin PWM fan cable to an available fan header on your motherboard or a fan hub.
- ARGB Lighting: Connect the 3-pin ARGB cables from the pump and fans to the included ARGB controller. The controller then connects to a SATA power connector from your power supply and optionally to a 5V 3-pin ARGB header on your motherboard for software control.
Operating Instructions
Once installed and powered on, the ABKO P360 Poseidon ARGB cooler will automatically begin cooling your CPU. Fan speeds are typically controlled by your motherboard's PWM settings, which can be adjusted in the BIOS/UEFI or via motherboard software.
ARGB Lighting Control:
The ARGB lighting can be controlled in two ways:
- Via Included ARGB Controller: If you connected the ARGB cables to the included controller, use the physical buttons on the controller to cycle through lighting modes, adjust speed, and change colors.
- Via Motherboard Software: If you connected the ARGB controller (or directly the ARGB cables) to a compatible 5V 3-pin ARGB header on your motherboard, you can use your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync) to synchronize and customize the lighting effects.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your liquid cooler.
- Dust Cleaning: Periodically clean the radiator fins and fan blades to prevent dust buildup, which can impede airflow and cooling performance. Use compressed air or a soft brush.
- Tubing Inspection: Occasionally inspect the FEP tubing for any signs of kinks, leaks, or damage.
- Fan Noise: If fans become excessively noisy, check for dust accumulation or loose mounting screws.
- No Coolant Refill: This is a closed-loop AIO system and does not require coolant refills. Do not attempt to open the cooler as it will void the warranty and may cause damage.
Troubleshooting
If you encounter issues with your ABKO P360 Poseidon ARGB cooler, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to pump/fans/ARGB | Loose or incorrect power connections. | Check all power cables (SATA for ARGB controller, 3-pin for pump, 4-pin for fans) are securely connected to the PSU and motherboard. |
| High CPU temperatures | Improper water block mounting, insufficient thermal paste, dust buildup on radiator, pump failure. | Ensure water block is securely mounted and thermal paste is applied correctly. Clean radiator fins. Check if pump is running (listen for a faint hum or check BIOS/software for RPM). |
| Fans not spinning or ARGB not lighting up | Incorrect fan/ARGB connections, faulty fan/ARGB controller, software conflict. | Verify fan PWM and ARGB connections. Test with the included ARGB controller if using motherboard software. Check motherboard BIOS/software settings for fan control and RGB. |
| Unusual noise from cooler | Air bubbles in the loop, loose fan screws, pump cavitation. | Orient the radiator higher than the pump to allow air bubbles to settle in the radiator. Ensure all fan screws are tight. If noise persists and performance is affected, contact support. |
User Tips
- Radiator Placement: For optimal cooling, consider mounting the radiator as an exhaust at the top of your case to remove hot air. If mounted at the front, ensure it's configured as an intake to bring in cool air.
- Cable Management: Plan your cable routing before installation to ensure a clean build and unobstructed airflow.
- Thermal Paste Application: While a pea-sized dot is common, some users prefer the 'X' or 'line' method. Ensure even spread for best contact.
- BIOS/UEFI Settings: Configure your motherboard's fan curves in the BIOS/UEFI to balance cooling performance and noise levels according to your preference.
- ARGB Synchronization: If using motherboard software for ARGB control, ensure all necessary drivers and software are installed and up-to-date.
