Before we move on, I had asked Aqua Computer what led to the development of the LEAKSHIELD and got a reply directly from the company's CEO. Here is the quote below: "The idea for LEAKSHIELD was born several years ago. At that time, we developed and built cooling systems for data centers used by banks. The requirements for operational reliability are extremely high and the customer expressed the wish to have all pipes double-walled. The D5 NEXT has an integrated OLED display that shows, among other things, the current flow rate and temperature, via the integrated temperature sensoris read out. Integrated switches also allow configuration directly on the pump itself, without additional control software or a controller. An integrated RGB LED strip also provides atmospheric lighting. Anyone who still wants to control and configure the pump via the sophisticated aquatune software can connect it to the motherboard via a USB 2.0 port. In addition, firmware updates are also recorded. Power is supplied via a SATA connection. It is not always easy to visualize what to do by merely reading instructions. So my goal here is to use many screen shots, and walk you through how I set up my two Aquaeros and the Aquasuite software on this particular build.

Set Point controllers can adjust power to keep the temperature of the assigned data source constantly equal to the target value if possible. Two point controllers can switch assigned outputs on and off when the temperature reading of the data source rises above or falls below predefined values. Monitor mode is more passive, acting purely as a means to detect any leaks as a result of pressure changes. The LEDs turn green, and you can use this mode with a much lower negative pressure of ~50 mbar vacuum. The third mode is Release, which, as we saw before, simply vents air into the system after having turned off the vacuum pump and associated valve. If an alarm triggers, and believe me it will, the default setting has the LEDs light up an aggressive red along with a buzzer alarm from the unit coupled with any system-specific shutdown actions if programmed with the optional accessory cable. Unfortunately, this is where things dropped from the high I was operating in during testing. I was working with older firmware most of the time, but using the LEAKSHIELD without having configured the alarm settings was a mistake I would not want you to make. The pressure gauge is far too sensitive otherwise, with even the valves in the LEAKSHIELD alone not 100% leak-proof to the sensitivity of the thing. Once configured to ignore "minor" leaks, you need to really put some effort into identifying the associated pressure and flow-rate changes, after which things do get much better. This way, even a broken pipe - and the pipes had diameters of 25mm - would not have been a problem. In the end, the project was realized without such a system, but the idea remained in my head. Such a system would have been too big and too expensive for our usual water cooling systems. So I started to develop concepts of such a system which are small and easy to integrate. Today's LEAKSHIELD is the result of a series of ideas and a puzzle that in the end became the finished product. Once the Firmware is updated you can remove the USB cables, and just use the Aquabus cables for control. It's absolutely fine to leave both Aquabus and the USB cables connected if you would like too, that’s what I do. It makes future firmware updates much easier. If no RGBpx products are connected to the pump, the RGBpx header can be configured as an aquabus interface. In this configuration, the pump can be connected to an aquaero 5 or aquaero 6 as an aquabus expansion device, giving the aquaero control of pump and fan output settings. Additionally, coolant temperature and flow rate are transmitted to the connected aquaero. A maximum of two D5 NEXT pumps can be connected to an aquaero simultaneously.

If I could get the Farbwerk settings to save, I would use Porfile 2 with all the same settings as the first profile except with the lighting off. Profile 3 is the same as Profile 1 except I shortened the Radiator Fan Curve to 3° max instead of 6° which just makes the fans ramp up faster. Power everything down again; you can disconnect the USB cable as it is unusable. Connect the Aquabus high port to a Hubby7 or the Aquabus high port on the Aquaero XT. Then you can connect your wiring for the extra fan channels to the Aquaero LT. You can actually add a third Aquaero for up to 12 channels of control if you need more channels. The Aquaeros all come with four channels of fan control. Since I have two Aquaeros I have a total of eight fan channels. I have six radiators in total, 4 x 560, and 2 x 280 with a total of 30 140mm fans. I also have one 120mm fan in the HDD cage, and one 120mm fan in the rear of the case for exhaust.

I actually got started with my Aquaero by reading a guide written by Namron, a member here on OCN. He passed away several years ago, and all of the links to his guide are broken or missing. It was getting rather dated at this point, and was based on the Aquaero 5. I was originally making this guide for my build log The Big Red "Devastator", but I thought more people would be able to find it if I made a separate thread. So I'm posting it in it's own thread, and on my build log. I’ve really only ever used the Curve Controllers so that’s the only one I’ll be showing here. I have seen the other controllers used when for example if you want your fans to completely shut off under light load, or have your fans ramp up and down to keep your coolant between certain temperatures. Besides being a fully autonomous USB fan controller, the QUADRO can also be used as an aquabus extension to an aquaero 5 or aquaero 6. In this configuration, the four fan channels of the QUADRO can be controlled by the aquaero, temperature sensor inputs and flow sensor input are transmitted to the aquaero. A maximum of two QUADRO controllers can be connected to an aquaero simultaneously.Aquabus cables are just four pin fan cables with female connectors on each end. You can easily make your own if you have the tools, connectors, and terminals. Alternatively to the LED strips offered by Aqua Computer, LED fans made by Corsair and NZXT can be connected using the optional accessory RGBpx Splitty4 (item code 53267, not included in delivery).
