For easy installation, the controller unit can easily be detached from the motor unit. This is immensely convenient for installation - all cables can remain plugged in to the controller unit while the motor unit is being installed into a pump top/cover or reservoir.

In the Data Source box I selected the Water – Air Delta Virtual Temperature Sensor that was set up previously. In the Outputs box outlined in red on the right side I added all four fan channels that control the radiator fans as well as the one fan in the HDD cage on channel 7. I might move that channel 7 onto its own controller later, but for now this will work fine. 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. 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. I’m going to have the name of the Current tab>Sub tab on the top of most screen shots, and I am also going to outline a red box around that particular tab to make it easier to follow along.

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. When everything is done and working you should export your calibration settings and save them somewhere where you will find them again if necessary. The four fan channels of the QUADRO can be configured independently, the high maximum power output of 25 watts per channel allows for connecting multiple fans to each output of the QUADRO using suitable splitters. In addition to setting fan speed manually, fan speed can also be controlled by temperature. In temperature controlled mode, set point controllers as well as curve controllers are available. If the corresponding temperature falls below the set limit, connected fans can either be switched off or be kept running at an adjustable minimum speed. For secure fan start-up, an intelligent start boost with speed signal monitoring can be configured for each fan channel. A temperature sensor directly connected to the stainless steel housing of the pump ensures a very accurate coolant temperature sensing.

In the right red box you can see I added Ambient Top to the end of the label for the ambient sensor located on the top of one of the top radiators. Also there is a second ambient sensor located in front of the left front radiator. I would like to say one more word: the only thing I am sorry about today is the fact that we have been producing water cooling systems for 20 years and this product is only coming to the market today. It would have helped so many customers and brought water cooling into completely different areas. Nevertheless, I am of course pleased that we are taking an important step into the future today! The OCTO is connected via USB 2.0 to the mainboard and 4-pin Molex to the power supply. The connected fans and other elements are controlled using aquasuite software. This makes it easy and convenient to set up, control, monitor and visualize all processes and sensor data.In addition to the flow, the high flow NEXT also measures the coolant temperature and the electrical conductivity of the coolant. Over time, the anti-corrosion effect of the coolant can decrease. This can lead to corrosion on coolers and deposits in the system. In the worst case, these can even result in the failure of the system. By measuring the conductivity, the high flow NEXT determines the quality of the coolant and gives you the opportunity to intervene before the system is damaged.

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. 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.

Once you start the Aquasuite program the Aquaero will show up, and a warning comes up that shows the firmware is out of date, and this device will not function with this version of Aquasuite. I also use the Start Boost feature, this just turns the fans on max speed for the time specified which is set for 5 seconds here, before they drop down to the controlled speed. This Curve Controller right here alone makes the investment into the Aquaero very much worth it! What makes this type of set up so awesome is that the fans will only slowly ramp up and down with your coolant temperature. 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.

In addition, the aqua computer OCTO provides two RGBpx outputs for digitally controllable LEDsready. These can control up to 180 LEDs with many effects. Each LED can be configured individually in color and brightness. In addition to the proprietary RGBpx LED products from aqua computer, RGB products from other manufacturers can also be connected to the OCTO fan controller using an optionally available adapter . There is also an input for a flow sensor. This means that the OCTO is in good hands even in a water-cooled system. The eight 4-pin PWM fan connections of the aqua computer OCTO fan controller can be configured individually. Thanks to the high output power of 25 watts per channel, it is also possible to connect several fans to an output of the OCTO using suitable splitters. Overall, the OCTO can deliver up to 100 watts of total power. The four inputs for temperature sensors also enable temperature-controlled operation of the fans. There are two water temperature sensors one in a front radiator and one in a top radiator. It looks like the last two letters got erased on sensor 3 in this screen shot. The rest of the sensors you see there are default sensors. The fan amplifiers can get warm when using voltage controlled fans under heavy load. Now that the Aquasuite software is installed, all the firmware is updated, and all the MPS devices are set up, it’s time to setup the temperature sensors, fans, and make some Curve Controllers which all happens in the Aquaero tab.There is an OCN Aquaero Owners Club if you haven't already seen it. None of the links on the OP work anymore, and if I posted it there it would just get lost. By constantly monitoring motor parameters and coolant temperature, a sophisticated algorithm is used by the controller unit to calculated the current coolant flow rate. The accuracy does not match the accuracy of an external flow sensor, but is entirely sufficient for monitoring purposes. Alternatively, a mechanical flow sensor can be connected to the fan output for a more accurate flow measurement. Another warning states the slave unit will not be recognized by USB any longer and will only work over the Aquabus connected to the main Aquaero XT. Also keep in mind that the only outputs that will work on the slave unit are the four fan channels, the temp sensor inputs, and you can add a second flow meter to the Aquabus low port. All other outputs are now disabled. I actually save frequently to both Profile 1 and Profile 2. Profile 1 is my main everyday profile, I keep Profile 2 the same in case I want to try something a little different than what is on Profile 1, and I can do that without messing up Profile 1.
