4. Opsætning og installation
4.1 Kontrol før installation
- Carefully inspect the radiator for any signs of damage that may have occurred during shipping.
- Verify that all included components, as listed in Section 2.2, are present.
4.2 Montering af radiatoren
- Identify the desired mounting location within your PC case. Ensure adequate clearance for fans and tubing.
- Attach your 120x120x25mm fans to the radiator using the provided M4x30mm screws. For a Push/Pull configuration, mount fans on both sides of the radiator.
- Mount the assembled radiator and fan unit to your PC case using the provided M4x5mm screws. Do not overtighten screws to avoid damaging the radiator or case.
4.3 Tilslutning til kølekredsløbet
The EK-Quantum Surface P120M features five G1/4" threaded ports for connecting fittings and tubing. Plan your loop carefully to ensure optimal flow and accessibility.
- Install appropriate G1/4" fittings into the desired inlet and outlet ports.
- The fifth G1/4" port, typically located on the end tank, is specifically designed for draining the loop and assisting with air bleeding. Ensure this port remains accessible for future maintenance.
- Connect your tubing to the fittings, ensuring all connections are secure and watertight.

5. Betjening
Once the radiator is installed, the cooling loop is filled with coolant, and all air is bled from the system, the radiator will begin to passively dissipate heat from the circulating coolant. The effectiveness of heat dissipation is directly influenced by the airflow provided by the attached fans.
The 18 FPI (Fins Per Inch) fin density of the EK-Quantum Surface P120M is specifically optimized to achieve a balance between thermal transfer capabilities and air resistance. This design allows for effective cooling performance even at lower fan speeds, contributing to quieter overall system operation. For maximum cooling, ensure fans are operating at appropriate speeds and are not obstructed.

6. Vedligeholdelse
Regular maintenance is crucial for ensuring the longevity, efficiency, and optimal performance of your liquid cooling system.
6.1 Rengøring
- Kølerfinner: Periodically inspect the radiator fins for dust buildup. Use compressed air to gently clear dust and debris from between the fins. Ensure the system is powered off before cleaning.
- Fans: Ensure that the attached fans are clean and free of any obstructions that could impede airflow.
6.2 Coolant Replacement and System Flush
- Follow your coolant manufacturer's recommendations for coolant replacement intervals.
- Utilize the dedicated G1/4" drain port on the radiator to facilitate easy and complete coolant draining.
- When replacing coolant or performing major system maintenance, consider flushing the entire cooling loop with distilled water or a specialized flushing agent to remove any accumulated residue or contaminants.
7. Fejlfinding
This section addresses common issues you might encounter with your EKWB EK-Quantum Surface P120M Radiator.
7.1 Dårlig køleydelse
- Ventilatorbetjening: Verify that all attached fans are spinning correctly and are not obstructed. Ensure they are connected to a power source and receiving appropriate voltage.
- Air in Loop: Trapped air in the cooling loop can significantly reduce performance. Thoroughly bleed the system by tilting the PC case and running the pump at varying speeds until all air bubbles are expelled.
- Støvopbygning: Excessive dust on the radiator fins can restrict airflow. Clean the fins and fans as described in Section 6.1.
- Kølevæskeflow: Ensure the pump is operating correctly and there are no blockages in the cooling loop (e.g., kinked tubing, clogged components).
7.2 Utætheder
- Øjeblikkelig handling: If a leak is detected, immediately power off your system and disconnect it from the mains electricity.
- Undersøg forbindelser: Carefully inspect all fittings and connections for tightness. Ensure O-rings are properly seated and not damaged.
- Komponentskade: Check for any visible cracks or damage to the radiator, tubing, or other components. If a component is found to be faulty, it must be replaced.
