The Aqua Computer Aquastream XT USB Eheim 12 Volt Liquid Cooling Pump was released in October of 2007 and has a significant increase in the range of its functionality compared to the previous model. The pump can interact with your computer using an internal USB cable and the Aquasuite software (downloadable via a link below). The pump can easily be monitored and controlled by your computer using the software suite. The pump report back temperatures from a thermal probe and even monitor a flow meter (probe and meter are not included) - all viewable through the Aquasuite software.

Among the new features is that the aquastream XT USB reports the pump rotation and automatically determines the maximum frequency so that reliable operation at maximum pumping capacity is guaranteed. All of the electronics circuitry is integrated into the back of the pump, including the power, USB, fan, Temp. probe and flow meter connectors. The pump chassis isn’t widened at all to accommodate the new electronics. Eheim’s proven mechanics still power the pump, providing reliable, smooth liquid flow that in unmatched by any other manufacturer. Compared to previous models, the aquastream XT has increased the head lift to 4.2 meters! This makes the XT one of the most powerful pumps on the market and it still remains virtually silent.

This performance increase is achieved through intelligent control of the unit using complex algorithms and onboard sensors that monitor rotor position, power consumption and input voltage (among other things) about 1000 times per second. The pump can operate at up to 6000 rpm! The pumping rate is automatically determined by the pump or can be controlled via the Aquasuite software. In either case, the optimum pumping efficiency is determined for you – though you can adjust it to your liking if you want less noise or more flow.

The computer receives a constant stream of data from the pump via the USB cable – this data is processed by the software and can be displayed on screen so you can check on your pump’s status at any time. Plus, the pump reports a fan-compatible tachometer signal to the motherboard so that your motherboard will automatically shut down your system in the event of a failure in the pump.

The pump features several internal temperature sensors and power level monitors that are all part of the pump’s intelligent protection functions. These programmed protection values protect the pump’s circuitry from potential damage and will trigger alarms in the software suite. If connected to the pump, a temperature sensor cable and flow meter can also trigger alarms – the software suite has freely configurable alarm thresholds and parameters.

Note: This pump does NOT come with fittings. The options below are defaulted to 1/4" ID compression fittings. These are the native fittings for Eheim Pumps. Other fittings are offered below but will require the adapters that are available below as well.
(You can deselect the default fittings)

• The pump generates a fan-compatible tachometer signal that is sent to the motherboard using the included cable, allowing your motherboard to automatically shut-down in case of pump failure.

• The pump circuitry has de-aeration program that can be activated by attaching the included jumper. Of course, de-aeration is best achieved by filling the liquid cooling system.

• The pump interfaces with the Aquasuite software via an internal USB cable that connects to your motherboard’s internal USB header. All important data (operating mode, power consumption, voltage levels) is reported to and monitored by the software.

• The pump has a number of automatic protection protocols including high temperatures, under voltage, low rotor rotation and more! The pump can even run with as low as 10.5 volts!

• The chassis wasn’t enlarged – in fact it is the same size as the stock Eheim 1046.

• The pump is still useable as a submersible pump!
