Hi SoMBrA,

I would power the pump via molex and use PWM for regulation. This gives you the added security, because if the PWM connection fails, the pump should just default to 100% power and also you don't have to worry about the minimum starting voltage etc.

Kind regards,
Boris.

Yup, channel 4 is the one with the PWM regulation.

PA's are just like an additional fan channel on the Aquaero itself, so basically the same like the first three channels on the Aquaero.

They do support higher loads and the Ultra version supports temperature regulation by using the temperature input on the PA. I can't really say that they provide any advantage over using the PWM control.

Depends on your preferences in the end, I have my pump connected to PA2 (power controlled) and it works as advertised, no problems.

Kind regards,
Boris.

PA2 acts exactly as any other channel if it is connected to Aqaero over Aquabus. It can also be used stand-alone (this is when the Ultras temperature regulation feature comes in handy), but if you connect it to Aquaero you basically get one more output channel, one extra temperature sensor connection and one extra water flow sensor connection.

Once PA2 is connected over Aquabus to the Aquaero you can control it like any other channel on the Aquaero itself.

Most of the people actually use water/ambient delta for controlling the fans, as the general consensus is that the temperature of the CPU/GPU changes to rapidly and too often to be reliable for temperature control. Basically, you can start an application which will take your CPU to 100% for a couple of seconds, bringing the temperature up. If you are controlling the fans from that it would speed them up unnecessarily because the temperature of water will hardly notice this short CPU load.

I have my loop set up to keep the temperature of water within 6C of the ambient temperature. Usually, everything within 10C is considered good.

Also, there is a problem of placing the temperature probe correctly on the CPU/GPU. You want it as close to the chip as possible, but you have to be careful not to interfere with the water-block/chip contact as well.

You can use the Software sensor tool which can provide you with 4 temperatures from programs like AIDA64 or Open hardware monitor. You can then use this as any other sensor in Aquasuite. The sensor tool is still in Alpha, so it is a bit flaky, and it only provides 4 sensors.

Kind regards,
Boris.

does it matter weather you use Power controlled vs RPM controlled for fans and pumps?

i don't know what the difference is, but when i change it there is about a 90 RPM difference.

Hi SoMBrA,

Sorry for the late reply, I am traveling...

You can read about my experiences with the ATX break adapter and wiring in the following post.

The standby line is only really necessary if the Aquaero is not connected to your computer over USB, or USB is not providing the power for some reason while the computer is in standby.

Kind regards,
Boris.

Hi SoMBrA,

I have my RGB LED setup so it shows the primary colors depending on the temperature ("cold", "nominal", "hot").

I just tried mixing up the colors in the RGB controller but the results were not really that satisfying. Maybe I am doing it wrong.

I am using my LED inserted in the reservoir with one of these , but I also like the idea of one of the users from the forum who took out the HDD LED from his case and replaced it with the RGB one. If your case is on the desk next to you it is a great way of quickly assessing the system status.

Kind regards,
Boris.

I have a PA2 and have my D5 Pump connected to it using the 3 Pin Connection next to the Molex Power Connection. I have my PA2 Connected to my AQ5 (LT) via the High Speed Aquabus, but nowhere can I find a way to control the Pump. Can you help me ? I did connect the PA2 to the USB all by itself and ran Aquasuite 4.72 to set the PA2 address to 50. Then I removed the usb connection from the PA2 and connected via Aquabus . But see no pump or RPM or way to adjust the power. Sounds like you have done this.

If you mean the standard D5 pump

The speed can not be controlled via the 3 pin cable ... it is only for monitoring the speed of the pump.
To control the speed of these pumps they need to be powered by the PA2 directly and voltage controlled.

Edit: Just read your thread on this and you obviously understand this already. Not sure why you are having probs. You should post screenshots and pictures of your setup, it makes it a million times easier to diagnose problems. I have no experience with the PA2 but others here will have.
