1. Introduktion
This manual provides detailed instructions for the installation, operation, and maintenance of your Alphacool Core 100 Aurora D5/VPP Reservoir with VPP655 PWM Pump. This product is designed for integration into custom PC water cooling loops, offering both efficient fluid circulation and aesthetic lighting.
The Alphacool Core reservoir features an integrated pump top for D5 pumps and includes a VPP655 PWM pump. The reservoir tube is constructed from acrylic, while the D5/VPP pump top and lid are made of acetal. This combination provides a functional and visually appealing design. The unit also incorporates 12 digitally addressable RGB LEDs in the pump top, creating a light tower effect within the acrylic tube.

4. Opsætning og installation
4.1 Monteringsmuligheder
The Alphacool Core 100 Aurora offers versatile mounting options:
- Case Bottom Mounting: Use the provided feet to secure the reservoir to the bottom of your PC case. Ensure adequate clearance for tubing and connections.
- Fan/Radiator Mounting: Utilize the included 120mm/140mm mounting frames to attach the reservoir to available fan spaces, directly to radiators, or to fans already mounted on radiators. This allows for flexible placement within your system.

4.2 Connecting to the Water Cooling Loop
The reservoir features three G1/4" connection ports. Typically, one port serves as the inlet from the rest of the loop, and another as the outlet to the pump. The third port can be used for filling, draining, or as an additional sensor port.
- Install your G1/4" fittings into the desired inlet and outlet ports. Ensure O-rings are properly seated and fittings are tightened securely by hand, then a quarter turn with a wrench if necessary, to prevent leaks.
- Connect your tubing to the fittings, ensuring a snug and secure fit.

4.3 Power and RGB Connections
The VPP655 PWM pump requires a 4-pin Molex power connection. The integrated aRGB LEDs require a 3-pin JST connection.
- Connect the 4-pin Molex connector from the pump to an available 4-pin Molex power cable from your power supply unit (PSU).
- Connect the 3-pin JST connector from the aRGB LEDs to a compatible 3-pin 5V addressable RGB header on your motherboard or an external aRGB controller. Ensure correct polarity to avoid damage.

4.4 Filling the Loop and Leak Testing
After all components are installed and connected:
- Fill the reservoir with your chosen coolant. Do not fill completely; leave some air space for expansion.
- Perform a leak test. It is highly recommended to use a dedicated PSU for the pump only, or to use a PSU jumper, to power the pump without powering other PC components. Run the pump for at least 24 hours, checking for any leaks.
- Once leak testing is complete and no leaks are detected, you can power on your full system.
5. Betjeningsvejledning
5.1 Pump Operation (VPP655 PWM)
The VPP655 pump is a PWM (Pulse Width Modulation) controlled pump. This allows for dynamic control of pump speed based on system temperatures or user preferences via your motherboard's fan headers or a dedicated fan controller.
- Connect the 4-pin PWM cable from the pump to a 4-pin fan header on your motherboard (e.g., CPU_FAN, PUMP_FAN).
- Configure the pump speed curve in your motherboard's BIOS/UEFI settings or using motherboard software. The pump operates within a control range of 800-4800 RPM.
- Ensure the pump is always running when the system is powered on to maintain coolant circulation.

5.2 Digital aRGB Lighting
The 12 digitally addressable RGB LEDs in the pump top provide customizable lighting effects.
- Once connected to a compatible 3-pin 5V aRGB header or controller, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion) or the software provided with your external aRGB controller.
- Explore various colors, patterns, and synchronization options to match your system's aesthetic.

6. Vedligeholdelse
- Udskiftning af kølevæske: It is recommended to replace your coolant every 6-12 months, depending on the coolant type and system usage, to prevent buildup and maintain optimal performance.
- Systemskylning: Before adding new coolant, consider flushing your loop with distilled water or a dedicated flushing agent to remove any old coolant residue.
- Rensning: If disassembling for cleaning, gently clean the acrylic tube and acetal components with distilled water and a soft cloth. Avoid abrasive materials or harsh chemicals.
- Pumpeinspektion: Periodically inspect the pump for any unusual noises or reduced flow. If issues arise, refer to the troubleshooting section.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Pump not starting/no flow | No power, incorrect wiring, air lock, pump failure. | Check 4-pin Molex power connection. Verify PWM cable is connected. Gently tilt the case to dislodge air bubbles. If pump is faulty, contact support. |
| Lækager opdaget | Loose fittings, damaged O-rings, cracked component. | Immediately power off system. Tighten all fittings. Inspect O-rings for damage and replace if necessary. Check components for cracks. |
| RGB LED'er lyser ikke | Incorrect 3-pin JST connection, incompatible header, software issue. | Ensure 3-pin JST is correctly connected to a 5V aRGB header. Check motherboard manual for compatible headers. Verify RGB software settings. |
| Reduced flow/poor cooling performance | Air in loop, clogged components, pump running at low speed. | Bleed air from the loop. Inspect radiators and blocks for clogs. Check pump PWM settings in BIOS/software. |
