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:

Please note: The pressure and inlet connections are identical with the Eheim 1046 pump. The adapter kit and suitable fittings have to be purchased separately and are available in the options below.

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

All other pumps a big step down from this in all ways. Get the basic cheaper model unless you are very very good with software. Discovered that hanging this down with direct coupling to reservoir is most efficient point in system to have a pump.

This is a great little pump. The first thing to note (as with all Eheim pumps) is that it runs cool. This means no radiant heat transmitted to the fluid for extra needed cooling. I have an HPPSi and this one is a souped up version of the HPPSi. Noise is slightly higher on this unit compared to the HPPSi. This one also draws more current. Lots of neat bells and whistles but to me whats most important is the flow rate and how cool the pump runs. This one does both well. No leaks, No problems as of yet. I would suggest to anyone to clean out your system at least once a year as gunk will build up over time slowing pump performance. Bottom line.. if you need plenty of power and flow rate for extra water cooling ie.. extra GPUs and such and dont mind a slight bit of noise then this is the pump for you. If your not cooling much more than the cpu,north bridge and perhaps one gpu then the HPPSi will be a good choice and run virtually silent. (Dont forget to purchase the adapter connections)

Thi is the best pump I have ever used. The flow on it is incredible. I am almost ashamed of how many MC655s I bought, when this baby was around the whole time. The only con is the custom fittings for in/out take. Those darn things SHOULD BE INCLUDED! For the price we''re paying. Be careful folks, you''ll be like me, you''ll over lookk it, and then have to wait 7-10 days to put that new rig together b/c you''ll grab some of your many regular adapters and realize THEY don''t fit! But alas, once I got over that trauma, all was good. ;) As always, FCPU was THEE best at shipping, packing, and all aorund communication. Peace, MWB
