This topic is of great interest to me also.

I am planing a large external radiator that will run twelve 140mm fans, and i was thinking of going with PWM fans. But from what I see here, that sounds like a no go.

Would voltage control fans be a better solution for a 12 fan radiator as long as total watts stayed below the aquaero per channel threshold?

It depends a lot on the fans themselves. I have run 10 Vardar fans on a single channel without any problems.
The corsair fan issue has been partially addressed with the newer version of the Aquaero and they can generally control more of them now.

You can use everything that is conductive.

I've written a lot regarding the Aquaeros, the A6 in particular, regarding their PWM implementation.

The PWM version of the D5 pump, and the PWM Corsair fans have been a bit problematic.

If you do an advanced search with IT Diva as the username and PWM, Corsair as the keywords, (tick the" posts only" box, not "entire site") you'll get 3 pages or so of relevant posts.

If you do an advanced search with my name and PWM, "sink current" as the keywords, you'll get pages about PWM. (tick the "posts only" box)

A quick copy paste from one post explaining briefly how to look at PWM in a PC:


In actuality, a PC PWM controller based on the Intel PWM standard, "pushes" no power at all.

It sinks current to ground.

Each PWM controlled device is responsible for supplying its own 5V level.

Therein lies the problem as you add greater numbers of controlled devices . . . . . the amount of current that the controller has to sink to ground rises, and manipulating Ohm's law, voltage dropped equals I squared R, the drop across the protective resistors on the controller's PWM input raises the logic low voltage level that the controlled devices see above the threshold to where it isn't seen as off-time any more, and you loose progressively more low speed control as you add devices.


It's a much better analogy, and much more accurate to think of it as, "the signal current level of multiple devices overwhelms the controller," than that "the controller signal becomes too weak as more devices are added".

I still haven't been able to set up my Aquaero 6 so that the CPU_FAN header sees its speed signal. I'm running Windows 10 Pro 64 bit, Asus Deluxe Z97 mobo with the latest BIOS. Here are a couple of screenshots from Aquasuite, showing my overview page and my alarm actions. What should I change to get this to work? Thanks!!





EDIT: This is the alarm configuration page for the High Flow USB, which shows there is no speed signal. I believe this is the problem. How do I activate it? It's selected in the top frame, but it appears to be off.

Hello IT Diva, I need some help with my workaround to the pwm pump mod, I couldn't find an 3.3k resistor only found a 2.2k and I'm using a single MCP655 pump its ok to use the mod with it 5.1 Zener diode, 560ohm resistor and 2.2k ??
post #5647 of 11169
Okay, so I bought an Aquaero 6 Pro. Now this may be a silly question, but how do I turn this thing on?

I've connected the four-pin molex power plug to the aquaero at one end, and the SATA connection on the PSU at the other. The PSU is on, and receiving power. What's next?


Apparently my power supply doesn't provide power through the SATA connection until it receives a signal from the motherboard to do so. The Aquaero 6 turned on as soon as it started receiving power from the SATA output on the PSU.

Looks like I'll have to use another power supply if I want to operate this without a computer.

[quote name="jvillaveces" url="/t/1474470/ocn-aquaero-owners-club/5610#post_24453844"

- How do I get the AQ6 to report a speed signal to the mobo so I don't have to configure the CPU_FAN header to "ignore"? The manuual says something to the effect that the alarm functions need to be configured appropriately, but I haven't been able to figure *** that means

- I could never get the PWM headers to work, despite having bought the appropriate connections. I tried (single color) LED strips from 4 different manufacturers and couldn't get any of them to work. Is this user error or is there an obscure trick to getting these ports to work?

- The Aquabus-low bus was disabled with the latest firmware. Is that port on the AQ6 imply dead or is it available as a second Aquabus-high port?

- What keyboard and mouse inputs is the AQ6 passing to the PC? Can this activity be stopped or paused so it doesn't interfere (on Win 10) with programs such as screensavers or BOINC that activate after a certain time of no keyboard/mouse activity?[/quote]

One thing that I see is that there is no data source for any of your alarms. Not sure what version of Aquasuite you are running?

As mentioned before I recommend that you connect the rpm port to a fan header on the aquaero to check if it is working at all. The fan header that you chose must be assigned to a controller that is set to at least 1% of power because 0% means there is no power at all and therefor the aquaero will not check if there is a rpm signal.

The action "speed signal on" for the aquaero is enough. Your alarm settings in the mps have nothing to do with that problem.

Is there a Linux software for the 6 xt? I know aerotools-ng for the 5.
