You need to do more research.

If you insist on six PA2's without an Aquaero 5 controller be aware of what you will have.

First, you will need six(6) USB header connections to the motherboard, one for each PA2.

You will need six temperature sensors, one for each PA2.

You will have six (6) 3 pin variable voltage fan output power connectors.

I am not sure if the Aquasuite 2012 will load and run without an Aquaero 5, but it would be required to control the PA2's



In answer to one of your other questions, I estimate six PA2,s can power over 100 fans of the type you are talking about.

Bytales....I think you need to first decide how many channels you want to be able to control. To be honest...you could power up all 35 fans with just one Aquaero XT. But the problem there is...you will be limited to 4 channels, and that may not meet your needs. For example, I have my "pull" fans on a separate channel from my "push" fans. At idle temps....the "pull" fans will spin down to zero, while the "push" fans will spin slowly. As water temps increase, I'll spin up the push fans faster before the pull fans ever start spinning. I couldn't tell for sure how your radiators will be split among your dual loops, but I'll propose something below, and you can adjust and provide the thread more feedback as necessary. I'm assuming you have two 120.4 on one loop and the other two rads (120.4 and 120.2) on the other loop:

Channels
- 8 push fans on Loop 1
- 8 pull fans on Loop 1
- 6 push fans on Loop 2
- 6 pull fans on Loop 2
- 4x 40mm and 1x 120mm case fan (all rear case fans)
- 2x 120mm case fan (not sure where these are...but I'm assuming you may want to control them separately)

With an arrangement like that above...you would need 6 channels, ....although I would always suggest planning for future growth. For 6 channels, you would either want to do 1x AQ5XT and 2x PA2's......or 1x AQ5XT and 1x AQ5LT. Would be a little cheaper to get the two AQ5's....but the PA2 option would provide more headroom on a couple channels if you ever needed it. The two AQ5's would be a slightly cheaper option...but only by a little.

If you wanted to combine all 7 case fans into one channel....and put all 12 fans on Loop 2 on one channel, ....you could actually get by on just one AQ5 (XT or LT) and expand it at a later time. The LT is only like $80 bucks or so. Very inexpensive way to start.

I agree with Larry's comments below, that you should reconsider using 6 separate PA2's without an AQ5. Not being able to share temp sensors among the 6 PA2's would make the solution less desirable.

Question is how many fans can a single power adjust power ?
If one must make the ampere voltage multiplication,
Noctua NF p12 Fan
on specification has the following specifications
Input Current 0,09 A
Voltage Range 12 V
Does that mean it will have a 0.09x12=1.08 W
and i can power with a single power adjust aprox 20 fans ?

Yes....you can power a lot of fans with a PA2. The first question though is how you want to be able to control them. Figure out how many channels you want to be able to control separately first...then you can figure out the right setup for your system.

There is another thing that is important and never gave it a thought
THe Noctua NF-F12 PWM has a 4 pin connector.
The aqua aero has 3x3 pins and the Power adjut has also 3 pin connector.
How am i suppose to connect a fan to these 3 pin connectors when the fan is equipped with a 4 pin connector ?

The 4th pin is the PWM control, and you don't need to utilize that. You can use your fans with any of the 3 pin power channels on the AQ5.

My two cents:

1) yes, that is correct. yes, that is accurate. depends...different size wires are rated for different loads. personally, I would probably use something thicker than 26 awg if I was stringing a whole bunch of fans together. But the typical runs (lengths) in a computer are so short that you can use much smaller wire than an electrician's guide would call for.
2) yes. but you will need some ear plugs if you are really thinking about putting in such fans.
3) yes. and power usage of the fan would drop....but not necessarily the power drawn from the wall.
4) yes.
5) yes it can decrease the voltage. that is really the whole point of the aquaero.

Could one power Adjust 2 power 4 Sanyo denki Fans 120mm 38m Fans ?
Specifications:
Manufacture / Brand: Sanyo Denki
Model / Part Number: 109R1212H1011
Size / Dimension: 120mm x 120mm x 38mm
Rated Voltage: 12 VDC
Rated Current: 0.52 Amp
Rated Input Power: - Watt
Fan Speed: 2600 R.P.M. (Revolutions per minute)
Maximum Air Flow: 102.5 CFM (Cubic feet per minute)
Noise Level: 39 dB-A
Maximum Air Pressure: - mmH2O
Bearing Type: Ball
Termination: 12” with 3 Wire Leads

I Thinks 4 of them would be on the limit
Theoreticaly :
0.52A x 12 V = 6.24W
6.24W x 4 = 24.96
Power Adjust is rated at 25W Maximum and 48 W startup.
Would that go flawless without problems ?
If so, these are the fans to be had.
Then i'll post my Fan Setup

Yes...you could run them, but nothing is ever flawless.

But I'm pretty sure those fans won't operate below 10 volts. If that's true...it negates most of the reason to use the Aquaero and PA2 in the first place. If you can't significantly undervolt them...you can't do a lot to change their speed or their loudness. If you are set on these fans....scrap the Aquaero and power them directly from your PSU. But...buy some ear plugs first. This system will be LOUD!!

Bytales - what are you planning to cool with 24 or more fans?

Impressive. It looks to me that you'll be generating something in the range of 700 +/- 100 watts or so, max.

You may be right about the voltage. I don't own one.....but was looking at the specs listed that I found online. The specs tabon this site lists an operating voltage range of 10.2 to 13.8 volts. If you are unsure....you might order just one first and make sure its what you really want.

Since you have so much radiator capacity...have you considered running quieter slower fans? I'm doing the same thing in my build with radiators. I've got a lot of them. But I'm using a lot so I could get away with silent fans running around 800 rpm or so. No single radiator in my build will cool as well as it could with louder high speed fans....but I've got so many of them that I'll have fantastic cooling anyway.

Good luck with your build!

I'm sure you wouldn't be the only one who would buy such a pure software controlled fan controller from Aqua Computer...I need such a thing for not less then 18 Fans. But the AC Staff is stubborn "...there is no need for a fan only controller...", because you could use an Aquaero 5 as master and an Aquaero 5 LT as slave and a few Power Adjust 2...and...and...and...to realize it. But for me it's like needless patchwork...most of the functions of an Aquaero are not used when you only need it to control fans...lots of fans. It's like buying a Ferrari to drive to the next bakery to buy a few buns in the morning, when you only need a bicycle or walk by foot.

Do you know some software controlled pure fan controller on the market?....Nor am I....It's a gap in the market I think.

The bitfenix recon can be software controlled with the Pheobetria third party software. A new version with fan curves will be released soon.
It is a far simpler device but also lower powered.
I have tested and it works with the bitspower and AC water temp sensors

Thanks for the info Jakusonfire, it's a nice piece auf hardware...you can even control the fans over internet with your smart phone video. BUT, and that's his biggest flaw, only 5 fans and a maximum of 10 ampere are not enough when you have much more fans, like 18 or even 35...and...it's not compatible with the Aquaero and the Aquasuite...

Oh yeah totally, its just a nice device for simple systems that offers more functionality than other fan controllers without being a complex computer system in its own right like the Aquero
