Details
The Aquacomputer D5 Next RGB is a D5 coolant pump based on the renowned Laing D5 pump. Its detachable controller unit is equipped with an OLED display, a PWM fan output and RGBpx lighting. It is the pump motor without a top: it needs a compatible D5 pump top/cover or reservoir to run, for example the ULTITOP D5 pump top (41123).

Detachable controller unit with OLED display
Aquacomputer calls the D5 NEXT a coolant pump with outstanding functionality. The Laing D5 motor runs on a ceramic bearing, which Aquacomputer chose for optimum durability and smoothness. The controller unit pulls straight off the motor unit, and Aquacomputer's key point here is easy access to the electrical connectors. All cables can stay plugged in to the controller unit while you install the motor into a pump top/cover or reservoir. Only detach or re-attach it with no power supplied to the pump.
A high resolution OLED display, mechanical buttons underneath it and a touch slider on the bottom side let you configure and adjust the pump even without a PC. The pump can also be configured and monitored over its USB 2.0 interface, and the firmware can be updated via USB. Additionally, current data from the PC, such as temperatures or processor usage, can be sent to the pump. Eight further values can be transferred this way using the aquasuite software, and they can drive the pump, the fan output or the RGBpx illumination. Other features include an alarm buzzer for acoustic alarm indication.
Decoupling and illumination
The silicone decoupler in the box keeps vibrations to a minimum, and Aquacomputer describes the result as whisper silent operation. A mounting plate fits into the silicone part for vertical pump installation, and the black mounting bracket, also in the box, holds the pump on a vertical surface. Without the decoupler, a flat silicone insert goes into the control unit instead. Six integrated RGBpx LEDs sit below the decoupler or insert and light the pump, and they also give light effects and alarm indication.
Coolant flow and temperature sensors
An integrated water temperature sensor sits directly on the stainless steel housing of the pump, for very accurate coolant temperature readings. The controller unit also estimates the coolant flow rate from motor parameters and coolant temperature with a sophisticated algorithm. Aquacomputer says that estimate is less accurate than an external flow sensor but entirely sufficient for monitoring. For a more accurate reading, the fan output can alternatively be used as a flow sensor input for a mechanical sensor such as the high flow LT (53291) or high flow 2 (53292).
PWM fan output
The fan connector is a powerful PWM fan output with up to 25 Watts of power and speed monitoring. That is enough for multiple fans on suitable splitters. Fan speed can be set manually or controlled by temperature, with set point controllers and curve controllers among the versatile control options. When the temperature falls below the set limit, the fans are switched off or kept at an adjustable minimum speed. An intelligent start boost with speed signal monitoring secures fan start-up. The output is compatible with PWM fans with four pin connectors only, and it has overload protection.
RGBpx controller for addressable LEDs
Next to the six LEDs in the controller unit, the RGBpx LED output drives LED strips and fans with individually controllable LEDs, up to 90 addressable LEDs. Color and brightness are set per LED. Up to four groups of LEDs of varying size can be configured, each with its own visual effect from the 23 available effects. Many effects follow current sensor data, and sound-to-light effects visualize the computer's sound output. The AMBIENTpx effect replicates the border area of the monitor display on LEDs behind the monitor. LED fans made by Corsair and NZXT connect through the RGBpx Splitty4 (item code 53267, not included).
aquabus expansion device
The RGBpx LED output can alternatively be configured as an aquabus interface for connection to an aquaero 5/6, such as the aquaero 6 LT. The aquaero then controls the pump and fan output, and coolant temperature and flow rate are passed to it. An aquaero takes up to two D5 NEXT pumps at the same time.
What the loop needs
The pump is not usable on its own: it needs a D5 top/cover or reservoir, held in place by a fixation ring. Aquacomputer names the ULTITOP D5, the D5 pump adapter (41094, 41095) and the aqualis D5 reservoirs (34079, 34080, 34081, 34082). Because the controller unit comes off for fitting the locking ring, the pump also suits tops and reservoirs of many manufacturers. More are in our D5 pump tops section.
Power supply is via a SATA connector from your power supply unit. The USB cable goes to an internal USB 2.0 header and is not required for pump operation. Use Double Protect Ultra coolant or water, never a coolant with solid micro particles: those in various opaque coolants damage the D5 pump bearing. The impeller must point up or to the side, never hanging downward, and the pump must not run dry.
aquasuite software
The aquasuite software gives a comfortable setup, evaluation and visualization of all sensor data. System requirements are Windows 10 or newer and an internal USB 2.0 port. Activating the pump gives you the current aquasuite version with an upgrade service for at least eighteen (18) months. After it ends, you may keep using and reinstalling the latest version from that period with no time limit. The update service can be extended or renewed for a fee, and installation and activation need an internet connection.

Notes
- Internal flow measurement: after deaerating the system, the pump has to run with blocked coolant flow for a short time to calibrate. Kinking a hose does it; with hard tubes a ball valve in the loop is required (not included).
- A fan and a flow sensor cannot be connected at the same time.
- RGBpx products and an aquaero 5/6 via aquabus cannot be connected at the same time.
- With the silicone decoupling fitted, the touch slider is out of reach; the mechanical buttons still work.
- AMBIENTpx effect: screen content protected by DRM or similar methods cannot be used for the effect.
