Opsætning og installation

Proper installation is crucial for optimal cooling performance. Follow these general steps. Refer to the detailed diagrams in the included printed manual for specific socket instructions.

1. Prepare the Radiator and Fans

1. Attach the two Pure Wings 3 140mm PWM fans to the radiator using the provided screws. Ensure the fan airflow direction is appropriate for your case's ventilation.
2. Connect the daisy-chained PWM fan cables to a single PWM header on your motherboard or to the included adapter cable.

2. Install the Radiator in Your PC Case

Mount the radiator assembly to an available fan mounting location in your PC case (e.g., top, front, or rear). Use the appropriate screws for your case. Ensure there is sufficient clearance for the radiator and fans.

3. Forbered CPU-sokkelen

1. Identificér din CPU-sokkeltype (Intel LGA eller AMD AM).
2. Install the correct backplate (if required) and mounting brackets for your socket type onto the motherboard.
3. Rengør CPU-overfladen med isopropylalkohol for at fjerne støv eller gammel termisk pasta.
4. Apply a small amount of the provided thermal paste to the center of the CPU's integrated heat spreader (IHS).

4. Monter pumpen/kølepladen

1. Carefully place the pump/cold plate assembly onto the CPU, aligning it with the mounting holes on the brackets.
2. Secure the pump/cold plate with the appropriate screws, tightening them in a diagonal pattern until snug. Do not overtighten.
3. Connect the pump's 4-pin power cable to the designated CPU_FAN or AIO_PUMP header on your motherboard.

Betjeningsvejledning

Once installed, the Pure Loop 3 liquid cooler operates automatically based on your motherboard's fan and pump control settings. For optimal performance and acoustics, it is recommended to configure these settings in your motherboard's BIOS/UEFI.

• Pumpedrift: The PWM pump features a 6-pole motor designed for quiet and efficient operation. Ensure the pump is connected to a dedicated AIO_PUMP or CPU_FAN header that provides continuous power or is configured for PWM control based on CPU temperature.
• Ventilatorbetjening: The two Pure Wings 3 140mm PWM high-speed fans are daisy-chained for simplified cable management. Connect them to a single PWM fan header. Configure a fan curve in your BIOS/UEFI to balance cooling performance and noise levels according to your preferences.
• Indledende opstart: After installation, power on your system and monitor CPU temperatures using monitoring software. Ensure the pump is running and fans are spinning. A slight gurgling sound may be heard initially as air bubbles are purged from the loop; this should subside quickly.

Opretholdelse

The be quiet! Pure Loop 3 is designed for low maintenance. However, periodic checks can help ensure long-term performance.

• Støvrensning: Rengør regelmæssigt køleribberne og ventilatorbladene for støv med trykluft eller en blød børste. Sørg for, at ventilatorerne ikke drejer under rengøringen.
• Genopfyldningsport: The Pure Loop 3 features an easy-to-access refill port on the pump unit. Over time, a small amount of coolant may evaporate. If you notice a significant increase in CPU temperatures or hear unusual pump noises, you may need to top up the coolant. Use only high-quality, non-conductive liquid cooling fluid specifically designed for AIO systems. Refer to the be quiet! website for recommended coolant types and detailed refill instructions.
• Rørinspektion: Occasionally inspect the flexible sleeved tubes for any signs of kinks, leaks, or damage.

Fejlfinding

If you encounter issues with your Pure Loop 3 liquid cooler, consider the following common troubleshooting steps:

• Høje CPU-temperaturer:
  • Ensure the pump is running and connected correctly to a motherboard header.
  • Verify that the fans are spinning and installed with the correct airflow direction.
  • Check if the cold plate is making proper contact with the CPU. Re-seat if necessary, ensuring thermal paste is applied correctly.
  • Inspect the radiator for dust buildup and clean if necessary.
  • Check coolant levels via the refill port if temperatures remain high after other checks.
• Unusual Noises (Gurgling, Whining):
  • A slight gurgling sound during initial startup is normal as air purges. If it persists, gently tilt your PC case to help trapped air move to the radiator.
  • Ensure the pump is not running at excessively high RPMs if controllable.
  • Kontroller ventilatorbladene for blokeringer eller skader.
• Ventilatorer der ikke drejer:
  • Verify fan cables are securely connected to the motherboard header or adapter.
  • Check BIOS/UEFI settings to ensure fan control is enabled and not set to a very low RPM curve at idle temperatures.
• Pumpe kører ikke:
  • Ensure the pump's 4-pin cable is securely connected to the correct motherboard header (AIO_PUMP or CPU_FAN).
  • Check BIOS/UEFI settings to ensure the pump header is enabled and receiving power.
