The last pump of the review is Asetek new Waterchill Xtreme 12V with reservoir. This pump is controllable by software via USB and makes the pump truely unique. NOTE: the pump starts at a speed of (3000 tr/min) when power by Molex alone. ASTEK info

First thing one notices is the immense size. It is really imposing! This is the biggest pump in this comparative review with a 16cm Lx7cm Wx9cm H with compresion fittings. This makes it larger than Eheim 1250 to give you a small idea. It really will be necessary to make room to use this pump but remmember there is a reservoir being integrated that does help. This still limit the purchase of the pump due to size...

The remainder of the kit is complete and has 2 temperatures probes, USB cord, the CD with software, a small manual in French(english), Water Wetter (anticorrosion + anti seaweeds), an molex cable to power up the pump, and 2 self-adhesive pads for the probes. Tubing of 10 and of 12 mm is also included especially for me, but is not in a normal package:

The version tested is the more powerful Xtreme with reservoir with a maximum flowrate of 3780 tr/min. There is also a standard version, slower speed, and turning in 3000 tr/min. I used the Xtreme for overclockers to see how the change in power works. NOTE: The faster you change the speed of the pump the more you will reduce the service life of the pump. The extreme also comes with several options of color and fitting types.

Removing the reservoir, one notices that this one strangely resembles the former model SACEM L35 preceding kits. It is a matter of a modification of the pump to adapt it to the 12 V as for the Eheim HPPS. The reservoir does not occupy some does that a small party to the before (130 ml) and one fills it through a cork 1/4 of helped turn of a joint torique for the étanchéité. For the entry of the fluid, a tube goes to the bottom of the reservoir to unstop under the water level and avoid thus the noises of clapotis. In functioning, nothing to repeat, the reservoir does well his work to purge the air of the circuit.

The embouts are type raccords Plug'n Cool for tube 10 mm or 12 mm external following this that you choose. The linking between the pump and the reservoir étanchéifié once of more with a joined torique on the diameter when one fits together the two parties. For the jackys, a location is foreseen to light up the reservoir to the assistance of a LED in option:

Asetek developed a PCB that allows supplying the pump then to manage the connection USB, the 2 probes of temperatures (resolution 0.5 °C), the optional LED, an optional LCD and 2 canals of 24 W maximum (2 HAS) each intend for the regulation of several fans, the all pilotable directly under Windows XP or 2K. While dismantling the back, one sees well the noyage in the resin of the interior of the pump (typical for the pumps of aquariums) to avoid the currents circuits when one immerses a pump. The Waterchill 12V is not well evidently immergeable here!

The green wire, linked up to electromagnetic armor plating of the stator, is to connect to the mass (to the carcass) but my tests do not show no difference on the influence that the field has on a screen CRT. The electronics of this pump is different of the others pump brushless to electronic commutation of the comparative one. The motor is piloted by a flea TPIC017B that is only a bridge in H to 4 MOSFETs allowing the passage of a current until 3 HAS, therefore amply sufficient here. His functioning temperature measured is close to the 50 °C in normal conditions to 3000 tr/min. The motor some did supplied as an aquarium pump working to the 50 Hz (speed of the field turning) except that one sends of the 12 V and not of the 230 V to the stator.

The Waterchill is therefore a machine synchrone that always remains to the same rotation speed whatever the restriction of the circuit. There is not noise increase when the debit diminishes for the rotor does not accelerate. By default, one measures a nutrition frequency of the stator of 50.08 Hz (recreated from the continuous current thanks to the bridge in H), this is to say 3005 tr/min. It suffices to do to vary this frequency lightly (under Windows) to impose rotation speed desired and to do it to turn more or less quickly, this is to say of 43 Hz for 2880 tr/min to 68 Hz for 3780 tr/min.

The pump puts about 20 seconds to pass of his minimal speed to maximum if one decides abruptly to change it. Ca avoids losing magnetic clash of the rotor if the field turning accelerates too brutally. Nevertheless, that itself nonetheless produced some times and the rotor did not know anymore where to give head. The pump puts itself then to graze, to vibrate strongly for the rotor changes very quickly direction several times before rediscovering the good way:

This pump needs 5 V and of 12 V to work. The 5 V serves only to supply the electronics and the request in power is negligible since the current on the 5 V is measured to 19 mY only (be 0.09 W). The fans will serve themselves on the 12 V what's more of the pump and their tension will be chopped for some to lower the average value and slow down their rotation speed.

Software is furnished on CD, but it is preferable to download the last version in the section support of the site web asetek (currently in version 1.4.8). To the first connection of the pump, Windows recognizes it and installs a generic drive to manage it (it is capricious with certain). An official drive is nevertheless present with software, but it is not necessary to change it. The rapatriement of the data is done then all the seconds about:

Software again rather basal for this principally is visualisation once one chose its parameters, but it himself fabric to every new version. Currently, one can regulate the fans of 0 to 100% by not any 1%, regulate the pump of 2880 tr/min to 3780 tr/min by not any 60 tr/min (be 1 Hz), see the temperatures (good to 0.5 °C near in comparison with a gauged thermocouple), have the system of the fans and manage also all the options as one can graft on the inspector. Profiles can be created and recalled to keep réglages predefine following the position of the moment. One has thus a global view of his system of watercooling, the all manager easily by a software.

For the versions to come, one all can envision since it is only programming and one has access to all the necessary magnitudes. One there could integrate of the alarm, an automatic regulation of the pump and fans according to the temperatures given by the probes for example (thermorégulation), a little as Apple is supposed to do with the DDC. The new version of software is well more revives than the old ones that tended to freeze very quickly to the least parameter change. Brief, it is necessary to leave a little times to the programmer to improve again and again.
