Hi,


I have just finished my watercooling build (well ther's still a few things to fix) and the way I though I woud be able to connect everything seems to not be working so I am wondering what would be the proper way to connect all the components. I'm totally new to Aquacomputer products and need your (greatly appreciated) help.

Here is a drawing of how I have connected my 6 LL120 fans, and WC pump (Barrow on a distroplate) to the Octo and Splitties4 (I forgot on the drawing to draw the power of the pump but off course the pump is powered by a molex) :



When everything is plugged like that, None of my fans are working at all (they don't spin), but 4 of them have the Leds working (I assume, the 4 ones that are connected to the 1st Splitty).

I though (according to the manual) that it was possible to connect a splitty4 to another one (using In/out connectors) ?
Did I miss something about the fans PWM for them to be working when connected to the splitties ?

I finaly plugged the fans PWM directly to the Octo to power them and they work, but the cable management would be better if connected to the splitties.

Also, I am ordering a Rgbpx cable and connector to add a rgb hub on the Rgbpx 2 channel, can you please confirm it should work ? I intend to power all my WC leds (CPU block, GPU block, etc..), which are 5v 3pin Rgb



Thank you a lot for your help or advises.

Thank you so much for your answer, I'll get to plug the cables tomorrow (it's 3h30 am right now).

I forgot to ask but, I plugged the pump PWM on the 1st PWM Fan output of the Octo, and it turns out that when I play with the ouput power slider, the speed (about 4500rpm) doesn't change. Did I get something wrong again ?

Hi Speedy,

Thanks for your answer.
I use this pump (SPB17T PLUS) because I have a Barrow Distroplate (LLO11-SDB-V1), and it is the recommended pump by Barrow. It is directly attached to the distroplate with 4 screws and I don't think there's any top that would allow me to attach a D5 to the distroplate.
This is my first ever custom loop so my choices are not as enlightened as yours may be

Indeed, the pump has a little potentiometer but I though I would be able to control it through Aquasuite with PWM. It's not a big deal if it's not possible, but it would have been a plus
I'm going to RTFM just in case

Thanks all again for your help !

I finaly played with the potnetiometer. When I built my loop, I did put the potentiometer on its maximum setting.
I did put it to the minimum level, and found out that I could manage the PWM through Aquasuite now

Thank you Speedy !

I've finaly received my RGBpx cable (1015487) and adapter (1019287) so I could plug the rest of the RGB components.

I plugged the RGB hub (5V 3pins, see picture in my first post) to the RGBpx 2 port in the OCTO, and off course to Sata power plug.

On the Hub, I plugged :
- Barrow CPU WB (LTYK something) with barrow cable adapter
- Bykski GPU (N-RTX3090FE-TC) : front and backplate
- Barrow flow meter (SLFV1 RGB) with barrow cable adapter
- Distroplate Barrow LO11-SDB V1 with barrow cable adapter
- Water pump : Barrow SPB17-T PLUS with barrow cable adapter

CPU/GPU and flow meter work fine, but the distro plate and the pump seem to have problems.

The distro plate leds have very weak intensity
The pump is flickering.

I also notice that one led of the CPUWB stays always on (and green color).
Even when I turn off RGBpx, that led stays on, and the pump sometimes blinks too.

All the barrow components are LRC 2.0.


When I play with RGBpx in aquasuite, i notice that, as all these elements are connected to a hub, I only have one "controler" in Strip 2 that acts on my leds.


For example, if I set that controler only on Led #1 of the Strip 2, I have 1 led on each component (CPU/GPU//pump).
If I set it on Led #1 and Led #2, I'll have two leds on, on each component.
When I set it to Led #1, Led#2 and Led#3, here comes the flickering in the pump.


Do you have any idea what could cause these issues ?
I checked all the connections, and also changed the position of each 3pin connector on the hub, that did not change anything.


Thanks a lot for your help

Hello there,

Thanks for your help Remayz.

I followed your advice and made some tests.

First, I plugged the pump, directly on Octo's RGBpx2 port (so distroplate, flow meter and CPU/GPU were not plugged).
I did put a static color (red) to see if it worked properly. No flickering at all. The only weird thing I noticed, is that my fans (6 x LL120 on 2 chained splitty4, plugged on OCTO's RGBpx1 port) sometimes simultaneously make a White flash (maybe about every 1 or 2 minutes).

Then, I unplugged the pump and plugged the Distroplate instead (so still on RGBpx2). Now the distroplate is flickering and leds are very weak. Should be static Red but instead it (part of the strip) blinks from red to yellowish/greenish. So I assume there is a problem with the leds on that distroplate.

The white flash that I noticed when the pump was plugged doens't happen in this configuration.

I made a short vertical video to illustrate https://www.youtube.com/watch?v=-dqUd3BYI5U

If the solution is to get rid of the RGB hub, what can I use to replace that ? (I have 6x 5V 3pins Led components that would need to be plugged ideally).

Thanks again for your input !

-----
Edit : I resized my Led controler (Strip 2) in Aquasuite to 21 leds (there are 22 on the distroplate I think), and noticed that it stops the flickering.
I also tried moving the led controler (instead of from Led #1 to #21, the controler is on led #2 to Led #22 for example), this does not introduce flickering, the #22 led works properly. So this does not seem to be a strip problem, but more an issue with the number of leds to control ?

I am also wondering if the "weak intensity" of the strip is not just due to the way it is inserted in the distroplate (the leds are not facing you when you look at the distroplate, they are perpendicular, oriented toward the coolant).
-------

So as I see, the Splitty 12 ACTIVE has also 4 Corsair sockets, which means I could basically replace one of the two splitty4 by a splitty 12 (only for leds not for Pwm)?
As I have 6 rgb components, do you think I can use two two ways splitter cables ? <img src="https://www.docmicro.com/images/products/tag/EK-LoopD-RGB2-WaySplitterCable.jpg" alt="EK-LoopD-RGB2-WaySplitterCable.jpg" title="EK-LoopD-RGB2-WaySplitterCable.jpg" style="font-size: 0.81em;" />
