I was curious about a few things since it's been a while that I approached this.

First, how can one easily manage 20+ fans using PWM? Ideally I'd like to be able to do this through the motherboard, but is this impossible? I was looking at getting a few of these: https://www.amazon.com/Aquacomputer-.../dp/B01IZ1LB44 but I'm not entirely sure how all of that works. Does it still recognize the fact that each fan is an individual, or would I need to get something like a separate fan controller?

Second, is the splitter I mentioned above what I should be using? I would obviously need at least 3 of them (I say "at least" because sometimes my fans may not reach the splitter).

What would you guys do if money wasn't really an object?
Im using this Deepcool 10port pwm hub :

Using only 2 port from 10 actually xd fan1 = 9x Noctua NF A14pwm daisy chained / fan2 = Noctua 20cm pwm . No problems at all.

@xyeLz - given that you want individual readouts and control, this is your answer. It may cost a little more than the Corsair Commander Ultra Pro RGB Xtreme Killer Mega Controller, but you won't be saddled with Corsair's buggy software and lower quality components. It's worth the extra few bucks.

Yeah....the little girl hentai avatar is really creeping me out....

"Fan 2" would be the 4 pull fans on the same radiator, etc. What I find extremely frustrating/annoying about this setup is that I have no idea how to determine if a fan fails or isn't working. That's the only reason I was hoping for something that could keep track of the fans individually, if that makes sense.


The only way to track each fan is to have them separated per channel. The Splitty9 reads the RPM signal from one fan only and uses that to set the speeds for the other fans on that channel. There is no way to tell if one dies.

Quadros would give individual readouts, right?

Honestly... idk about everyone else but typically I control fans by the Radiator. Each radiator should be a monitoring point. All fans at the same speed, on the same header, controlled by the same slider.

Controlling and getting a read on all 20??? Pointless and stupidly expensive.

(I’m running 40+ typhoons for reference...) actually, 32 now since one rad finally failed.

@ 40 I had to run two radiators to one header, as I didn’t wanna deal with any further aquaero complexity. You’ll get tired of it eventually.

So I have my top cooling section (16 fans) on 1, front 8 on header 2, bottom 8 on header 3, pumps on 4.

Note - AQ6 clearly isn’t my power source, even though it’s built to power similar scenarios. I figure it’ll live longer if I provide external power to fans n pumps.

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.

Quadro's have 4 fan channels same as the Aquaero. So would work the same, individual fan is connected and it'll read that fan. Connect fans via a Splitty9 or some other fan splitter and it will only read the RPM signal from one fan. It's unpractical to control all.

I've actually gone even simpler. Intakes and rad fans (exhaust) are all on one curve using a hub. The rad fans are slightly undervolted with an inline resistor to give slightly more intake than exhaust. I did what felt like thirty separate curves when I had a larger loop in a Phanteks Primo, and it was a lot of headache for essentially no benefit.

I agree that it's insanely impractical. But.....the OP was inquiring about it.

Yep lots of complexity for no viable reason what so ever.

I like your idea too.

Get splitters that are powered from PSU not mobo but get signal from PWM controller of your choice: mobo, ...

Or get one of those powered splitter PCBs with around 8 ports I think those may actually have powered PWM. Or you could make one if you're worried about the load on PWM from one controller going to too many fans.

Or forget PWM and do good old voltage control, there you can use about anything to achieve your goal when you know the power demands.
