I've got a slightly unconventional set up, although this is OcUK so probably not that unconventional :p

https://forums.overclockers.co.uk/threads/external-rad-at-window.18794221/

I'm currently controlling everything via my Gene VIII which gets the water temperature from a XSPC inline sensor. However, I'd like to pick up an Aquaero 6LT for a bit more control over things. The slight issue I have is that the external rad fans aren't reachable with a normal fan cable.

The question I'm really asking is how many extension cables would it be OK to use? The external radiator is 480mm so that's 4*120mm fans. In order to get from the PC to the external rad, I need to link 3*4-pin fan extension cables. I would then have to use splitters to each fan. Is that feasible? The only alternative would be to run 3*4-pin fan extension cables from each channel, but then I wouldn't be able to control anything else (internal fans).

Is volts drop an issue when daisy chaining fans? Does anyone know the maximum daisy chain I can do on each channel?
 
Voltage drop is an issue whenever the lead length uses too small a wire size. Normal fan and fan extensions use small wire size so loose power when more than 1 extension is used on one fan. I suggest using a splitter hub and making your own leads with proper size wire based on total amp load of all fans running on the hub. 8-way hubs are readily available and work well. ;)
 
6LT arrived today and I'm very impressed with it. Only downside is having to dedicate a channel to the PWM pump, but other than that it's very versatile and the software is a breeze to use.
 
At least you multiple channel I have the 5 Lt and it only has one pwm channel. You can run multiple fans from one channel using a splitter, as each channel provide quite a bit of power so you should be fine really.

It’s a really good bit of kit though.
 
Hi,
Most people don't plug their pump into a PWM as its a bit pointless having it rise and fall based on small changes in temperature of your water. Just set it and forget it on the USB or Aquabus interface would be my advice and save the 4x4 pins for your fans.
 
@jasonmorris thanks for that.

I'm sure I read people saying they could set their fans up according to a delta between air temp and fluid temp, but all I can seem to do is set them up according to the temperature of an individual sensor.

Have I misunderstood?
 
Yes you can set up a delta i think you may have to setup a virtual sensor but it’s been a while since I did it, if you wait until I get home I’ll talk you through it.

While I have only used the 1x PWM channel with 4-pin header on my Aquaero 5 LT, I've been told by several people more knowledgable than I about aquaero controllers that there is at least 1 more PWM channel on the 2x 2-pin plugs just to the right of the 4-pin PWM header, and possible they are each different PWM channels. . Looking at connections from left to right bottom are 3x 3-pin fan headers and a 1x 4pin PWM header. Manual shows theses as Fan 1, Fan 2, Fan 3 and Fan 4

The next two fan headers are 2- pin PWM headers. Each pair of these pins are PWM and RPM. This means you have to supply power and ground to fan from another source, like from PSU ;)

No the aquaero 5 has 1 pwm channel and 3 3-pin fan channels. The aquaero 6 has 4 pwm channels.

Maybe you have not noticed the 2x 2-pin PWM headers next to the 1x 4-pin PWM header. Or are these 2-pin headers controlled by same channel as the 4-pin header?

You remember correctly.

There's own "tab" in Sensor's page for Virtual sensors.
They can be named similarly like normal sensors and besides normal physical sensors or software readings they can use also other virtual sensor as input.

Then in Controllers page sensor reading/data source is used as base for control curve, or some other function and finally wanted outputs are then connected to that controller.

Fan's page has other adjustments per individual channel, like type of control (PWM, power/voltage or speed), minimum and maximum (controller's output fitted inside these) speeds and start boost.

Yes sorry you are right I think I misread your question. I’m not sure how you would control those 2 headers though so perhaps someone else can clarify.

Thanks.

I am also finding that when I make changes to my fan curves, if I reboot the PC then they all revert back to what they were before. I can't see a save button anywhere? I feel like a total novice asking questions like that, but it's so annoying having to go through all the settings again. :o

You can save profiles so that all your settings are activated under different settings, as in summer and winter for example

Don’t worry the aquaero is so powerful and customisable that you will only really begin to scratch the surface. But you don’t need to know much to set up a basic system.

What program version are you using by the way?
 
"PWM" power outputs have 1A current limit and are not meant for fans or pumps.
(with 15kHz PWM frequency)

Though they can be assigned to controller just like fan channels.

Save button is in left side panel of Aquasuite.
In that "button" which opens Aquaero 6LT's main settings.
Don't remember exactly what it can save in one go, but better to use it when you've done settings in one page.


Profiles can be managed/saved in System-tab.
