6. Opsætning og installation
Proper installation is crucial for optimal cooling performance. Always refer to your motherboard and PC case manuals for specific guidance on component placement and cable routing. The following steps provide a general overview:
- Prepare the CPU and Motherboard: Ensure your CPU is correctly seated in its socket. Clean the CPU surface thoroughly if old thermal paste is present.
- Monter bagpladen: Fastgør den passende bagplade til din CPU-sokkel (Intel eller AMD) på bagsiden af bundkortet.
- Monter radiatoren: Secure the radiator and fans to an available mounting location in your PC case (e.g., top, front, or rear). Ensure fans are oriented for optimal airflow (intake or exhaust).
- Påfør termisk pasta: If not pre-applied, apply a small amount of thermal paste to the center of your CPU's integrated heat spreader (IHS).
- Install the Pump/Cold Plate: Carefully place the pump/cold plate assembly onto the CPU, aligning it with the mounting posts. Secure it using the provided screws, tightening them in a diagonal pattern to ensure even pressure.
- Tilslut kabler:
- Connect the pump's power cable to the designated AIO_PUMP or CPU_FAN header on your motherboard.
- Connect the fan PWM cables to the CPU_FAN or SYS_FAN headers. The DG240 supports daisy chain connection for fans.
- Connect the 5V 3-pin ARGB cable from the pump and fans to the motherboard's 5V ARGB header for lighting synchronization.
- Kabelstyring: Før kablerne pænt for at sikre korrekt luftgennemstrømning og en ren konstruktion.

7. Betjeningsvejledning
7.1. Fan and Pump Control (PWM)
The DG240's fans and pump utilize Pulse Width Modulation (PWM) technology, allowing your motherboard to dynamically adjust their speeds based on CPU temperature and system load. This ensures efficient cooling when needed and quieter operation during lighter tasks.
- Access your motherboard's BIOS/UEFI settings to configure fan curves and pump speeds.
- Most motherboards offer automatic fan control profiles (e.g., Standard, Silent, Performance) that can be selected.
- For advanced users, custom fan curves can be set to fine-tune the balance between cooling performance and noise levels.

This image highlights the performance characteristics of the DG240's fans, including fan speed (≤1800 RPM), air capacity (≤81.5 CFM), and fan pressure (≤2.3 MMH2O), demonstrating their high wind pressure capabilities.

7.2. ARGB-lysstyring
The DG240 features Addressable RGB (ARGB) lighting on both the fans and the pump head, which can be synchronized with your motherboard's ARGB software.
- Ensure the 5V 3-pin ARGB cable is connected to the correct header on your motherboard.
- Install the corresponding ARGB control software for your motherboard brand (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome RGB).
- Use the software to customize lighting effects, colors, and synchronization with other ARGB components in your system.
8. Vedligeholdelse
Regelmæssig vedligeholdelse er med til at sikre din AIO-kølers levetid og optimale ydeevne.
- Støvrensning: Rengør regelmæssigt støv fra kølerribberne og ventilatorbladene med trykluft eller en blød børste. Ophobet støv kan hæmme luftstrømmen og reducere køleeffektiviteten.
- Ventilator inspektion: Kontrollér ventilatorbladene for eventuelle blokeringer eller tegn på slid. Sørg for, at ventilatorerne drejer frit og stille.
- Slange- og tilslutningskontrol: Inspect the rubber hoses and connections for any signs of leaks, kinks, or damage. While the system is sealed, visual checks are recommended.
- Thermal Paste (Long-Term): The thermal paste applied between the CPU and cold plate typically lasts for several years. If you notice a significant increase in CPU temperatures over time, reapplying fresh thermal paste might be necessary. This requires carefully removing the pump, cleaning both surfaces, and applying new paste.
9. Fejlfinding
If you encounter issues with your darkFlash DG240 AIO cooler, refer to the following common problems and solutions:
