3.2. Preparació de la placa base
- Identify the correct backplate for your CPU socket (Intel or AMD).
- Attach the backplate to the rear of your motherboard, aligning the holes with the CPU cooler mounting holes.
- Insert the appropriate standoffs through the motherboard from the front, securing them to the backplate.
3.3. Installing the Radiator and Fans
The DG240 features a 240mm radiator with two fans. The fans are designed for high wind pressure and efficient airflow.

- Determine the optimal mounting location for the radiator within your PC case (e.g., top, front, or rear). Ensure adequate clearance.
- Secure the radiator to the case using the provided screws.
- Ensure the fans are oriented to push or pull air as desired for optimal case airflow.
3.4. Mounting the Pump/Cold Plate
The pump features a 3-phase 6-pole motor and a ceramic bearing for efficient and durable operation.

- If thermal paste is not pre-applied, apply a small, pea-sized amount to the center of your CPU's integrated heat spreader (IHS).
- Carefully place the pump/cold plate assembly onto the CPU, aligning the mounting holes with the standoffs.
- Secure the pump with the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.
3.5. Connexions de cable
The DG240 features ARGB lighting and PWM fan control.

- Connect the pump's 3-pin power cable to an available 3-pin or 4-pin fan header on your motherboard (usually labeled "AIO_PUMP" or "CPU_FAN"). Ensure it receives full power.
- Connect the fans' PWM cable to the CPU_FAN header on your motherboard. The fans support daisy-chain connection for simplified wiring.
- Connect the 5V 3-pin ARGB cable from the pump and fans to a compatible 5V 3-pin ARGB header on your motherboard. This allows for synchronized lighting effects.
- Organize cables to ensure proper airflow and a clean build.
4. Instruccions de funcionament
4.1. Engegada inicial
After installation, double-check all connections before powering on your system. Upon first boot, monitor CPU temperatures using system monitoring software.
4.2. Control del ventilador PWM
The fans are PWM-controlled, meaning their speed adjusts automatically based on CPU temperature. This provides optimal cooling performance when needed and quieter operation during lighter loads. You can configure fan curves in your motherboard's BIOS/UEFI settings or through compatible software.
4.3. ARGB Lighting Synchronization
The DG240 supports 5V 3-pin Addressable RGB (ARGB) synchronization. Connect the ARGB cable to a compatible motherboard header (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome RGB) to control lighting effects through your motherboard's software. This allows for unified lighting across your system components.
5. Manteniment
Un manteniment regular ajuda a garantir la longevitat i el rendiment òptim del refrigerador líquid de CPU.
- Eliminació de pols: Netegeu periòdicament la pols de les aletes del radiador i de les pales del ventilador amb aire comprimit. Assegureu-vos que els ventiladors no girin durant la neteja.
- Gestió de cables: Verifiqueu que tots els cables estiguin connectats correctament i que no obstrueixin el flux d'aire.
- Comprovació del refrigerant: As an AIO unit, the coolant is sealed and does not require refilling. However, inspect the tubing for any signs of leaks or damage.
- Soroll de la bomba: A slight hum from the pump is normal. Excessive noise or grinding sounds may indicate an issue and should be investigated.
