Product Information

The new aquastream XT pump is the completely redesigned successor to the well-proven aquastream Rev. 3.5. It presents the absolute peak of development of practically silent pumps for water cooling systems. But this pump is not only a pump, it is also a highly integrated microprocessor-controlled measuring- and control system for your cooling system. This truly unique system was even improved over the preceding system, greatly increasing the functionality of the unit. All version of the aquastream XT have an USB interface, allowing monitoring and control of the unit even without connection to an aquaero. The control functions are accessible via the popular and free Windows-software aquasuite. Depending on the unlocked software version of the pump additional features such as a fan output, temperature sensors as well as a connection possibility for a temperature sensor. In the maximum equipped version all important monitoring and control functionality for your water cooling system is already integrated in the pump.

The new features include turning detection as well as automatic maximum frequency measuring, ensuring reliable operation even at maximum power. In comparison the the previous versions of the aquastream XT the control unit was integrated into the pump's casing without having to enlarge the unit.

The pump in detail: Highest performance with smart electronics
The mechanics of the pump are based on the proved Eheim technology with yet to be matched smooth operation. Compared to the predecessors the pressure head was increased to sensational 4.2m. This means that the aquastream is one of the most powerful pumps on the market whilst still being almost completely silent. This was achieved with a highly intelligent control system with complex algorithms and sensors. Permanently and more than 1000 times per second the rotor position, current draw, power and voltage are monitored. From this data the perfect settings are computed, allowing the pump to run with up to 6000rpm internally, depending on the system.

The pump frequency is automatically set by the pump or can be set manually via the software. The pump finds the optimal operating point by itself.
The data is additionally passed on via USB or aquabus and can be read out and displayed in the aquasuite software. The aquasuite software is a system for all aquacomputer products which needs to be installed only once and offers an integrated database, network capability (maintenance also) and many control features.
Parallelly a rpm signal can be passed on to the Mainboard which allows an emergency shutdown if the pump fails.

Of course the aquastream XT is also equipped with the handy deaeration program which was introduced by Aqua computer years ago. This program can be started via a jumper or via the software. The program can even be configured to your own preferences.

The sensors of the aquastream XT: Water temperature included
No other competing product can offer the range of functionality and performance of the aquastream XT. Our R&D department has already integrated a sensor for measuring of the water temperature into the pump. The data from this sensor can be read via aquabus or the aquaero and used for adjustments. Additionally multiple temperatures are monitored in the power amplifier section. The pump has an intelligent protective system. If the temperature rises above the pre-programmed safety setting, the electronics are set into a safety mode to prevent damage. Depending on the temperature different strategies are used.
External connective possibilities expand the performance spectrum: An additional external temperature sensor and a flow sensor can be connected directly to the pump. Both are monitored with extremely high precision and can be integrated into the alarm settings. An unbelievable number of alarm settings and parameters can be set.

Integrated fan controller. Intelligent controllers for super-quiet operation of your system
You wish to have a high-performance cooling system with one of the best controlling mechanisms in the world? Then the aquastream XT is the perfect solution for you! The integrated highly complex PID controllers work in the microprocessor to achieve only one goal: To keep your system at the temperature you want and to keep it as quiet as possible! This is achieved with a mathematical model which calculates the fan speed settings and monitors the current speed more than 1000 times per second. Of course without the annoying noise from PWM a highly precise analogue voltage is put out. The starting voltage of your fan is also taken into account and automatically set by the controller.

You wish to have more control? Take it! All controller settings can be influenced by you in detail or can be set comfortably with pre-sets. The speeds can be adjusted following the internally measured water temperature, the external temperature or following manual settings.
Of course an alarm signal is given when the fan fails.
Additionally great attention was paid to highest operational safety: If a too high load is drawn from a fan socket the electronics automatically detect it. A switching of the output voltage to 100% reduces the thermal power loss in the system. If this is not enough the electronics are switched off and an alarm is triggered,

By the way: it is no problem to connect 3 airstream fans to the fan output. This means that even 360mm radiators can be controlled without problems.

Buy all features now - or when you really need it?
Development costs money, features need to be maintained and not every user needs every feature. Hence the aquastream XT is available in the versions Standard, Advanced and Ultra. This means that you only pay for what you need, offering you one big advantage: The pump can be upgraded after purchase! You only need to buy a key and enter it into the aquasuite software. This will unlock the additional features of the advanced- and Ultra version. The detailed features can be found here:

All versions:
- based on the technology of the proven Eheim 1046 pump, specially adapted to the specifications from Aqua Computer
- Full ceramic bearing of the pump rotor
- pure 12V pump - no higher voltages are created

Please note:
The pressure and inlet connections are identical with the Eheim 1046 pump. The adaptor kit and suitable fittings have to be purchased separately.
IMPORTANT: If you wish to install this pump in an aquabay, you will need a current connection kit and a current aquabay. Old version from before September 2007 are not compatible!

Test the aquabay software in demo mode:
In our support section a current version of the aquasuite software can be downloaded for free and used in demo mode. In this mode the menus and displays of an aquastream XT can be seen without a pump.

Should the product be shiped with an "origninal Aquacomputer quality seal" we wish to inform you that this seal often detaches itself. A detached quality seal is no justified reason for reclamation.

Important note:
The pump can be severely damaged if the USB connector is connected with wrong polarity. Such damages are covered by the warranty, Aquacomputer does not replace pumps which were destroyed by such mistakes!

Direct manufacturer support:
In case of a reclamation please send the pump with a photocopy of the invoice directly to the manufacturer: Aqua Computer Gmbh & Co. KG, Gelliehäuser Str.1, 37130 Gleichen, Germany.  Contact: 

We at Aquatuning are not able to inspect the pump and hence only forward it to Aqua Computer. the delay by this process can be eliminated if you send the pump to the manufacturer directly.

Note: A cable for connection of the aquastream pump with the aquaero is included with the pump.

Question from Moritz L. from 05. May 2016
Hallo, ist mit maximaler Systemtemperatur (35 Grad) gemeint, dass mein Wasserkreislauf nicht wärmer als 35 Grad wird oder nicht wärmer als 35 Grad werden darf (Zwecks Schäden etc.) ? Gruß :)
Antwort von Aquatuning GmbH vom 05. May 2016
Die Pumpe ist bis 50°C Kühlmitteltemperatur freigegeben
Antwort von Aquatuning GmbH vom 05. May 2016
in der Beschreibung ist ein falscher Wert angegeben, wird nun geändert
Question from Guest #281494 from 07. July 2017
kann man diese Pumpe unter wasser betreiben? oder geht das nicht wegen denn offenen kontakten hinten dran?
Antwort von Aquatuning GmbH vom 07. July 2017
Diese Pumpe können sie nicht unter Wasser betreiben. Sie benötigen dafür eine Tauchpumpe wie die Eheim Compact Reihe (Artikelnummern: 49009, 49010, 49011, 49012, 49062, 49067)
Question from Guest #251372 from 08. August 2017
Kann mit dieser Pumpe ein Kreislauf mit 2100mm Fläche betrieben werden? Genug Leistung vorhanden? 3x 560 Radiator (45mm) 1x 420 Radiator (45mm) Zu kühlen: 1x CPU + 2x GPU Besten Dank für die Hilfe.
Antwort von Aquatuning GmbH vom 08. August 2017
Dazu müssten wir mehr zum generellen Aufbau wissen. Stehen die Radiatoren aufrecht oder liegen sie? Gibt es mehrere GEfälle, Schnellverschlüsse und wieviel Biegungen sind geplant? Hier gibt es zu viele Punkte die man bedenken muss. Grundlegend könnte es reichen, wahrscheinlich wird die Pumpe aber zu schwach sein.
Antwort von Guest #251372 vom 08. August 2017
Drei Radiatoren sind liegend installiert (1x Boden, 2x Decke) und einer seitlich. Verschlauchung flex 16/10mm mit grossen Radien. Ansonsten nur noch ein Durchflusssensor. Schwierige Frage ich weiss...! Gäbe es denn eine stärkere Pumpe in Ihrem Sortiment, welche Sie empfehlen könnten?
Question from Guest #309956 from 06. June 2018
ist es möglich die Pumpe manuell einzuschalten um etwa beim erstmaligen befüllen die kühlflüssigkeit stufenweise im system zu verteilen?
Antwort von Aquatuning GmbH vom 06. June 2018
Ja das geht, nimm dazu einen ATX Überbrückungsstecker, schließe diesen an den Stromstecker vom Netzteil an. Die Pumpe über den 4Pin Molex ebenfalls an das Netzteil anschließen. Sofern das System befüllt wird, kann das Netzteil über den ON/OFF schalter ein und ausgeschaltet werden, wobei dann nur die Pumpe mit Strom versorgt wird. Das Mainboard bleibt ohne Strom. Ebenfalls wäre es über ein externes Netzteil von Phopbya möglich, die 34W Version reicht dazu bereits aus: Artikel Nr. 1013047.
