The most important info is missing: which fans do you use?
If your answer is Noctua or EKWB you can blame the fans for this problem.
Disappointed in the brevity of the reply. A short explanation would have been helpful.
Too often the consumer is bounced between manufacturers, being told 'it;s the other guys issue'.
The problem is exclusive to the splitty9 active?
I have a splitty9 (not active) driving nine Noctua A14 industrialPPC-2000 IP67 fans, on fan port 4 of an aquaero 6 XT with a curve controller.
I have 20% minimum power and no issues with PWM control.

Ok, thanks, actually as i suspected.The most important info is missing: which fans do you use?

I will try out another PWM splitter and see if the problem is solved.
20% minimum power is actually what i was aiming for, now i know it is possible and that fans are not the problem.
Thanks you very much, really appreciated!

Noctua had the great idea to add some kind of protection circuit to newer revisions of fans which is causing this problem. We do not know what they did there in detail but we know it is causing the problem because it is also Noctua that confirmed that to one of our customers. Their solution was that they offered the customer fans from an older batch that do not suffer from this problem.Disappointed in the brevity of the reply. A short explanation would have been helpful.

I guess your fans are from an older batch because otherwise you would have problems too.
There is no way for us to solve this - or at least not without raising new problems with regular working fans. We already sent out modified Splitty9 active boards for testing purposes to affected customers. Feedback so far is that it only partially helped but a normal operation with affected Noctua fans is still not possible. Noctua will have to fix this with a new revision and we know for sure that they are well aware of this problem.

I have an assortment of brand new A12 and A14 industrialPPC-3000's and I am also having issues. I actually was able to get the fan curves working for the fans but it seems intermittent and changes with each reboot.
Based on what I have seen playing with the software, the output will drop voltage even though I have PWM selected and seems unreliable from day to day. I have attached a picture of the settings that I have that seem to be working fine right now. My issues are the PWM is inconsistent and I will see fluctuations in rpm speed, will not maintain a base rpm speed and jumps from about 2k to 3k rpm with no in between setting.
Did you seer Shoggy's post above?

I did but it's not really a solution. I am trying to progress tweaking the software to at least get a workable solution. Otherwise, I just bought aquaero hardware/software that is useless.I have an assortment of brand new A12 and A14 industrialPPC-3000's and I am also having issues.

Look, I am a EE and I would like to solve this problem rather than point fingers and repeat that the fans or aquaero stuff is useless. Can you help me figure out a solution? That is my preferred method but if that is not an option, I'd like a refund for the aquaero stuff.Otherwise, I just bought aquaero hardware/software that is useless.
No, you bought fans that are useless!
Our device is not the problem.
I don't mind if I have to design a PCB interface myself but right now, I have hardware that cannot control my fans so I'm stuck otherwise.

What exactly do you expect now?! The manufacturer told you, that your fans are off the specifications and therefore can't be controlled as you like. Instead you try to "force" a solution where nothing is.Can you help me figure out a solution?
And instead of calling for help here and try to get a refund on the aqua computer hardware, maybe you should go to your fan manufacturer and ask them to deliver a solution or fans wich are in the correct specifications. I think you are on the wrong side of there problem here. Bother the fans manufacturer for help ...

This is good. Thank you for supplying this information. What are the 4 wires coming off the fans 1-4 on the aquaero 6 lt? There should be +12V, GND and what are the other two wires?Look, I just came here for facts and was met with rude words and hostility. I am waiting to hear back from Noctua but in the mean time, I wanted to see if there was a way to design a solution myself.
Instead of just explaining the exact issue, I was met with rude and hostile responses, coupled with condescending attitudes so now that I know how support reacts when I have an issue, I will be returning my entire aquaero setup.
Thanks
*EDIT*
It sounds like I can just redesign my own splitty9 and add a +12V to 5.5V switching regulator and then a 5.5V to 5V LDO and this should solve the issue.

You ask for solutions and will "design an pcb" to solve the problem, but you don't even know the four connections of a pwm fan?! How will that end up then?! Hilarious.What are the 4 wires coming off the fans 1-4 on the aquaero 6 lt? There should be +12V, GND and what are the other two wires?
