Setup and Installation

  1. Mounting the Reservoir:

    The reservoir can be mounted using the included magnetic fasteners or screws. Ensure a stable and level surface for optimal performance. The feet can be adjusted for minor height variations.

  2. Pump Installation (if applicable):

    If your reservoir did not come with a pre-installed pump, carefully insert your D5 or VPP compatible pump into the designated slot at the bottom of the reservoir. Ensure the O-ring is properly seated to prevent leaks. Secure the pump using any provided retention rings or screws.

  3. Connecting Tubing and Fittings:

    Connect your G1/4" fittings and tubing to the appropriate ports on the reservoir. Ensure all connections are tight but do not overtighten to avoid damaging the acrylic. Use the drain port for easy system draining.

  4. aRGB Lighting Connection:

    Connect the 3-Pin JST + 3-Pin 5V aRGB cable from the reservoir to a compatible aRGB controller or motherboard header. Ensure the voltage matches (5V) to prevent damage.

  5. Powering the Pump:

    Connect the 4-Pin PWM and SATA power cables from the pump to your power supply and motherboard (for PWM control). Refer to your motherboard manual for proper PWM header connection.

  6. Filling the Loop and Leak Testing:

    Fill your water cooling loop with appropriate coolant. Before powering on your entire system, perform a leak test. It is recommended to run the pump with only the power supply connected for several hours, checking for any leaks. Place paper towels around fittings to easily spot drips.

Operating Instructions

Pump Operation:

The pump (if included) is controlled via a 4-Pin PWM connection. This allows you to adjust the pump speed through your motherboard's BIOS/UEFI or dedicated fan control software. Adjust the speed to balance flow rate and noise levels according to your preference.

aRGB Lighting Control:

The integrated aRGB lighting can be controlled via a compatible 5V aRGB controller or motherboard software. This allows for synchronization with other aRGB components in your system and customization of lighting effects and colors.

Maintenance

  • Regular Inspection: Periodically check all fittings and tubing for any signs of leaks or wear.
  • Coolant Level: Monitor the coolant level in the reservoir. Top up as necessary to ensure the pump remains submerged and air bubbles are minimized.
  • Coolant Replacement: It is recommended to replace the coolant every 6-12 months, or as advised by your coolant manufacturer, to prevent buildup and maintain optimal performance.
  • Cleaning: When replacing coolant, it is a good opportunity to flush the system and clean the reservoir. Drain the loop completely, then flush with distilled water. For thorough cleaning, the reservoir can be disassembled carefully.

Troubleshooting

  • Pump Not Running:
    • Check all power connections (SATA and 4-Pin PWM) to ensure they are securely seated.
    • Verify that the pump is receiving power from the power supply.
    • Ensure the PWM header on the motherboard is correctly configured in BIOS/UEFI or software.
  • Leaks Detected:
    • Immediately power off the system.
    • Identify the source of the leak. Tighten fittings carefully, ensuring not to overtighten.
    • Check O-rings on fittings and the pump for proper seating or damage. Replace if necessary.
  • aRGB Lighting Not Working:
    • Ensure the 3-Pin JST + 3-Pin 5V aRGB cable is correctly connected to a compatible 5V aRGB header or controller.
    • Verify that the aRGB controller/software is properly configured and enabled.
    • Check for any physical damage to the aRGB cable or LEDs.
  • Excessive Air Bubbles in Reservoir:
    • Ensure the reservoir is adequately filled and the pump intake is submerged.
    • Tilt the system gently to help dislodge trapped air bubbles from radiators and blocks.
    • Run the pump at a higher speed temporarily to help bleed air from the loop.

User Tips

  • Pre-fill Test: Always perform a leak test with only the pump powered before connecting other PC components.
  • Coolant Choice: Use high-quality, purpose-built coolants for water cooling systems to prevent corrosion and biological growth.
  • Cable Management: Plan your cable routing for the pump and aRGB lighting to ensure a clean build and prevent interference with other components.
  • System Bleeding: Be patient when bleeding air from the loop. It can take several hours for all air bubbles to be removed, especially in complex systems.
