If Corsair SP120, get an Akasa 5-way PWM splitter or use 4 fans per Swiftech splitter when using motherboard headers. A stronger controller such as the Aquaero 6 can control 6 SP120s per channel at the moment though Darlene (IT Diva) is testing out somethings that may change that.
How serendipitous for you to offer up such a perfect segue . . . . .
This weekend after some testing on the initial PCB I made to work out the issues with the Corsair PWM fans, I thought that I could do better with a more flexible PCB with more testing options, so I revised that PCB, and just in the last few minutes finished etching it and got it ready to drill.
To go along with that, I ordered 4 of the PWM, SP120 2-Packs and the swiftech X8 splitter on Saturday from FCPU, and an assortment of parts from Digikey.
I was, at first, looking at having someone who already had a bunch of the fans do some testing, but without seeing on the scope what's really going on, that's just not a good way to get a verifiable result.
If my results are good, and I can mod the original PCB to the final component version of the new one, I may still do that to get end user feedback.
If I have the problem solved with 8 fans, I'll get 8 more and another splitter.
I think testing 16 on a channel should be enough, since if it still looks right on the scope with 16, then I know it'll do considerably more.
Assuming I get it all working, I can still sell the fans with a PCB in the "buy & sell" section, so I can justify spending the $ that way.
(Mostly I'm a nerd chick and have an OCD need to find answers)
Anyway, . . . .
Here's the new PCB ,top . . . . with the original test unit, lower:
Here's the PCB I'll be using in the Stretch Build to allow one of the Aquaero 6's to control the 3 pairs of PWM D5's:
Getting the Aquaero to work with the PWM D5's was pretty straight forward.
