Aqua Computer USB Hub & Splitty explained for liquid cooling stuff 

I mean the only way it wouldn't recognize it is if the USB cable on both weren't plugged in, or if the second one isn't plugged in to a molex cable for power. But I think you'd notice those situations. You might need to go into the windows device manager and remove them both. Otherwise they should both be there in Aquasuite.

@@kevinjbonn thanks I we give that ago

(Narrator here) My answer, from experience, is DO NOT DO THIS. I know that on paper the amount of watts and amps on the Octo and the Noctua (are you using the 3000 RPM ippc versions?) should work. But they absolutely do not in real life. Even using the Splitty 9 Active. If you are trying to power Noctua fans on the Octo, you should use no more than 2 per channel, regardless of what hub you have them plugged into. I tried to do a total of 12 Noctua ippc fans split into 2 splitty 9 actives, and I had a total of 5 of the fans die permanently. I ended up playing it very safe by using the Octo to do 2 per channel and that works safely. If I make it 3 per channel, I get the same "revving" effect. It sucks, but that's just how these beastly Noctua fans go.

Hi , I'm using the Chromax NF-F12 1500rpm , I have 3 per header on the Octo, The Aquasuite graph shows the ramping, though you can't see any slowing or speeding up on the fan. I'm just starting a new build with 4 x 480 radiators. One set will have the T30s the other will have the noctua push/pull , so 16 NF-F12s with Max imput current of 0.05 amps . Plan is too have 8 noctua run on one active splitty and 8 on another and plugged into the two fan headers on the Octo and the same with the Phanteks T30s . So four active splittys controlled from the Octo. It would seem on paper to be viable as each splitty has its own power to run the fans and the Octo is just really providing the PWM signal. What do you think. Thanks.

@@davidgreen424 hi,how is your sweet build,i'm also planing to my first watercool so i do need to power 13 p14max fan

@KhalidAlawaji Hi , it's slow , I am going to use five powered splitty9s with 8 fans per splitty. If you're going to use the splitty 9 powered, keep in mind that they can only deliver 4.5 amps across all 9 fan outputs. You could use one splitty9 and an Octo .

@@davidgreen424 alright,thank you for the replay,good luck

Always.

DO NOT DO THIS WITHOUT LOOKING INTO THE FOLLOWING.You will probably destroy all of these components at once doing this. While the rule of thumb is 3 fans per header usually, this is not always the case and 7 fans would definitely be a lot more than you'd want to chance. Each fan will have a rated amperage. That can be as low as 0.1A for a regular Noctua I pulled up or 0.38A for a corsair model. Either way, you need to figure out what the amp rating on the fans you plan to use is by looking up the exact specs. The D5 NEXT is surprisingly powerful, mostly because it has it's own SATA power source. This means that it will put out 25W at 12V. To get the amperage rating, you take the watts and divide it by volts so you end up with basically 2A. That's a lot more power than you'd see from most individual fan headers. But depending on your fan, you might find that's either quite a few or not so many. I only use Noctua's 3000 RPM iPPC Industrial 140 and 120's. The amps on one of those come out to a shocking 0.55A which means I can only put 3 of them on that pump. Which I wouldn't even do because I don't tend to have great luck with any more than 2 per header on an OCTO. You do NOT want to mess around with having just a little bit more than it's rated for. Like, mathematically, I certainly wouldn't want to put 4 of my Industrial Noctua fans on it for a total of 2.2A draw even though the rating is @2.08A. In fact, you want to keep it to about 80% to account for spikes which will blow out the header. Crazier still is that the Octo has 25W per header for a total of 100W. It's the same rating for those headers and yet, as I said I can only actually get two or 3 to work on each header properly. I have actually blown up an Octo as well as a Splitty 9 Active. As well as something like 8 of my precious Noctua fans. Learned the hard way. So, the Octo is actually great for what you're looking to do. Depending on which fan you're using, you could probably even get away with a Quadro. But even under the best circumstances, and in spite of the math mathing properly, I would never try more than 5 of ANY fan on a single header, preferably 4. It's not worth the risk, which is that every component involved after the PSU and the cables is destroyed without being repairable. Also, I wouldn't go with a D5 Next mounted at the bottom of an Ultitube. I might not even suggest a D5 Next PERIOD. They are extremely fragile and somewhat poorly designed in the sense that if your reservoir overflows (which they do pretty commonly when being filled) the fluid runs down the side and right into the crack between the pump and the D5 controller. There's a reason Aquacomputer sells replacement controllers and they're frequently out of them. They're cool in theory, but they don't offer any actual benefit over a "dumb" D5. Sure, they have a built in temperature sensor, but those are quite cheap. I have dozens of them sitting around. The alleged built in flow sensor is really more like "is it on or is it off?" as opposed to a real flow rate. It doesn't really do anything all that special. The Sata cable also loves to come loose on the back of them randomly and it's easy to break that stupid header as well. I've got two of them that I did surgery on to change over to "dumb" D5's after I got tired of having to mess with controller issues. They won't run at all unless the controller works properly. I would get a regular D5 and spend the money on a High Flow Next instead because it can actually measure the flow rate, the fluid temp, the conductivity of the fluid, and many other neat tricks. It's everything the D5 NEXT is not.

Thank you for your suggestion and your experiences. This opened up a doubt for me and also a certainty about where to go. I also sent a message to aquacomputer and they said that if I need control over the fans I have to have the OCTO. So for me it was like this: have a normal D5 with a High Flow and an OCTO. That would give me good control over what I need. *The fans I'll be using are Be Quiet Wings 4.
