Aquaero 5 XT extent of delivery

The list of accessories that come with Aquaero 5 includes:

  • 1x 5-pin USB cable with for internal connection
  • 1x aquabus/speed signal cable
  • 4x temperature sensors
  • 4x mounting screws
  • 1x remote control unit
  • 1x User and Installation manual
  • 1x Important notice

USB cable is almost 1 meter long which is enough to connect Aquaero 5 even in largest PC cases. Aquabus/speed signal cable is intended for connecting other devices (such as Aquastream, Multiswitch USB, Poweradjust 2) to controller via Aquabus — Aqua Computer’s proprietary interface. Sensors have 70 cm length with good in most cases, but can be short if, for example, you want to install it on a radiator outside PC. The remote control requires two batteries that are already included with the package.

All the electronic components are soldered on three PCBs that are mechanically connected to each other via four screws. This makes it easy to disassemble Aquaero 5 when needed, for example, when changing the cooling solution for power transistors or cleaning LCD of dust.

While comparing technical features of the novelty and its predecessor, details of which you can find in our review (Aquaero 4.0) we should outline the following noticeable changes:

  • All Aquaero 5 series products are equipped with a 32-bit 48MHz processor and flash-memory
  • Instead of blue/white display with 2×20 resolution, Aquero 5 XT and Pro version can boast of black/white graphics LCD with resolution of 256×64 px and refresh rate of up-to 20 pages per second.
  • PC connection interface upgrade — obsolescent USB 1.1 interface was changed to version 2.0. There was no point of implementing USB 3.0 as the speed provided by USB 2.0 is more than enough for needs to the controller. Moreover use of USB 3.0 could cause compatibility issues as it not as wide spread among system as USB 2.0 is today.
  • Fan control channel abilities were slightly enhanced. Max current load has increased from 0.8 А/Ch (Aquaero 4) to 1.65 A/Ch (Aquaero 5). The fourth channel now has support for PWM control. Control precision has been improved too. The total amount of fan control channels can be expanded by 6 additional ones provided via Power Adjust 2 modules.
  • Besides four fan channels, there are two additional ones that has support for PWM to. However, its max current load is limited to 1A and these channels are recommended to be used with lightning cathodes or LEDs
  • Previous experience with Aquaero 4, that could fail due to overload, has taught Aquaero 5 to avoid such problems, thus it gained individual channel current control and power transistor temperature display
  • Relay has been improved too — current load limit has been lifted from 0.5А of Aquaero 4 to 1.0A of Aquaero 5.
  • Aqua Computer uses Aquabus for data transfer between controller and branded periphery devices connected to Aquero. In Aquaero 5 this interface has been reworked and got a higher information rate.
  • Internal clock has now become a fully functional calendar.
  • The number of connected temperature sensors of the novelty amounts to 8, plus up-to four software sensors can be used now. Temperature measurement ranges has been expanded: from 0-100°С (Aquaero 4) to -40-120°С (Aquaero 5). Hardware testers will surely love the improvement in temperature sensor reading accuracy — it does no exceed 0.05K. Moreover, there are three integrated temperature sensors for controller element status check.
  • The company also has spoken about possibility to introduce special digital sensors for Aquaero 5. According company representative, these are only to be purchased through Aqua Computer e-store.
  • Control mode are more flexible to set compared to settings Aquaero 4 has. The new controller line-up supports up-to x8 Set Controller modes, or x16 Two point controller modes, or 4 Curve Controller modes. The last one allows custom control mode implementation.
  • LED control now support RGB modules
  • Additional, and IR transmitter can be connected to Aquaero 5 thus providing distant control over your system as well as your home appliances, for example, TV-set.
