As a new user of Aquaero Computer products, I think that I can properly answer question three.

The A5 XT has a total capacity of eight temperature sensory inputs of any combination. If you need additional temperature sensors, you will need to purchase a PowerAdjust 2 (henceforth, PA2) for each additional temperature sensory input desired. NOTE: each PA2 has ONLY one temperature sensor input. Since the A5 XT can be connected to a total of six PA2s (at this time), only fourteen temperature sensors are possible (AT 5 = 8 temperature sensors + six PA2s x 1 temperature sensor = 14).

I have the A5 XT and three PA2s. Thus, I have the capacity for eleven temperature sensors, of which I only use ten of the temperature inputs. I placed seven in-line temperature sensors in my loop automatically to control the corresponding fans on the radiators (via curve control). As the temperature rises, the appropriate fans increase in speed. Of course, as the water temperature cools, the fans spin slower.

I also have four general temperature sensors installed. One of these general temperature sensors is strategically placed between my Corsair 24 GB memory. As the temperature increases, the fan speed also increases to cool the memory. As the temperature cools between the memory, the fans spin slower. Ingenious!

I also have the aquaero power connect - 24 pin ATX standby power / ATX break. You will also need the Aqua Computer Plug for relay connector (3 contacts) in order to use the ATX Break + relay which maintains power to the A5 XT while the computer is off. Yes, power is maintained to the A5 XT while power is off, as long as you did not unplug or turn off the power switch on the PU.

I also use the flow sensor high flow G1/4 in my system, as well as the Aqua Computer tubemeter. Everything works well.

BEWARE: If you buy the flow sensor, you will need to purchase separately the connection cable. The connection cable comes with the tubemeter.
BEWARE: If you buy the tubemeter, the threads are G1/8 and not G1/4. You will need to purchase separately a a G1/8 to G1/4 fitting reducer.

"do you notice much different between the water temp sensors in the loop"

I have three rads for my MOSET and CPU (Intel i7 975 Extreme) of which water flows out to three more rads for the 2 x EVGA 590 GPUs. Under heavy usage (video editing for hours), the answer is no, I do NOT see much temperature difference. However, under light use, such as when I use MS Word to compose technical articles, at best I experience about 8C - 10C difference.

"I was hoping to get aquaero 5 LT, and use its inputs and connect them via some cable, not entire sure this is possible though, as getting Power adjusts just for their temp input would get pretty expensive."


I certainly use my PA2s for more than temperature sensory inputs. I purchased them to control my fans. I did not want to gang too many fans on any one power output, and thus increase the temperature when the fans are spinning slower (via curve control). I do not have more than four fans being powered by any single output. Of course, one may, but I chose not to do it.

At this time, only one A5 XT may be connected to a single motherboard via the USB cable between the motherboard and A5 XT, and up to six PAs may be connected to the A5 XT by daisy chaining one PA to the next, or by Y-cables.

The required cable comes with each PA2.
