4. Setup è Installazione
Follow these steps to properly install your be quiet! Pure Loop 2 240mm water cooling system. Refer to the video for visual guidance.
4.1. Preparate a scheda madre è a CPU
Ensure your CPU is correctly installed in its socket. For AMD AM5/AM4, remove the stock cooler mounts from the motherboard. For Intel LGA 1700, install the appropriate backplate and standoffs.
4.2. Applicà a pasta termica
Apply a small amount of thermal paste (included) to the center of your CPU's integrated heat spreader (IHS). A pea-sized dot or a thin line is usually sufficient. Do not spread the paste manually; the pressure from the cold plate will distribute it evenly.
4.3. Install Fans on Radiator
Attach the two Pure Wings 3 120mm PWM fans to the radiator using the provided fan screws. Ensure the fan cables are oriented for optimal cable management within your PC case.

4.4. Mount Radiator in PC Case
Secure the radiator, with fans attached, to an available mounting location in your PC case (e.g., top, front, or rear). Use the longer radiator mounting screws. Ensure proper airflow direction (intake or exhaust) based on your case's cooling strategy.
4.5. Installate a Pompa/Piastra Fredda
Carefully place the pump/cold plate assembly onto the CPU, aligning the mounting holes with the standoffs. Tighten the screws in a diagonal pattern, applying even pressure until snug. Do not overtighten.

4.6. Connect Cables
Connect the fan PWM cables to your motherboard's fan headers or the included ARGB/PWM hub. Connect the pump's PWM cable to the dedicated AIO_PUMP or CPU_OPT header on your motherboard. Connect the ARGB cable from the pump to a compatible 3-pin 5V ARGB header on your motherboard or the ARGB/PWM hub.
For detailed installation steps, watch the official installation video:

5. Operating Instructions
Once installed, the Pure Loop 2 240mm operates automatically based on your motherboard's fan and pump control settings. For optimal performance and acoustics, it is recommended to configure fan curves in your motherboard's BIOS/UEFI or through compatible software.
5.1. ARGB Illumination Control
The ARGB illumination on the cooling block can be controlled via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync). Connect the ARGB cable to a compatible 3-pin 5V ARGB header on your motherboard to synchronize lighting effects.

6. Mantenimentu
Regular maintenance ensures the longevity and optimal performance of your water cooling system.
6.1. Coolant Refill
The Pure Loop 2 features an easy-to-access refill port on the radiator. Over time, a small amount of coolant may evaporate. Use the included coolant bottle to top up the system when necessary. Refer to the installation video for the location of the refill port.

6.2. Pulizia
Pulite periodicamente a polvera da l'alette di u radiatore è da e pale di u ventilatore cù aria compressa o una spazzola dolce. Assicuratevi chì u sistema sia spento prima di pulisce.
7. Risoluzione di prublemi
If you encounter issues with your Pure Loop 2, try the following steps:
- Nisuna alimentazione / I ventilatori ùn giranu micca: Check all power connections (SATA power for ARGB/PWM hub, fan headers on motherboard). Ensure the pump is connected to the AIO_PUMP header.
- Temperature elevate di a CPU: Verify that the pump is running and the fans are spinning. Re-check thermal paste application and ensure the cold plate is making good contact with the CPU. Confirm radiator is not obstructed by dust.
- ARGB Not Working: Ensure the ARGB cable is correctly connected to a 3-pin 5V ARGB header on your motherboard or hub. Check motherboard RGB software settings.
- Rumore inusual: Check for loose fan screws or obstructions in fan blades. Ensure the pump is securely mounted and not vibrating against other components.
