this is cpachris's fan daisy chain. i think he has around 50 fans connected to an 8 channel fan controller (correct me if wrong)

I'm far from being an electrician, but I read about this awhile back when doing this on my water build.

It's 30W per channel

so 8 fans on each header would mean you can control the speed of all fans on one dial for that sincle radiater, do the same for the other. that said, a six channel controller will allow you to have four spar for your chassis fans
alternately you could wire four fans (each side of rad) to one header and use two fan controllers (four or six channel) and lessen the strain on the controller

Exactly.

The main reason why I would do this (I to am a strong proponent of "push/pull", but more times than not, I just buy 1450 RPM fans and run them without any speed control, that way the noise is always the same ... quiet) is that in a "push/pull" config, you REALLY SHOULD never have the speed of your "push" and and your "pull" fan be different. This will actually hurt your cooling capabilities if, for example, you have the "push" fan spinning at 2000 RPM, and the "pull" only running at 800 RPM (or visa versa), because the slower fan on will end up starving the faster fan of the pair the air that is it trying to move. So as a MINIMUM, you should have your "push/pull" fans on the same controller channel that way they always run at the same speed.

And to be honest, there really isn't any great advantage to having one set of fans on your radiator running at 2100 RPM, and the next set of fans on the same radiator running at 800 RPM and the next set of fans on the same radiator running at 1500 RPM. That is why I would just get either a 6 or 8 way splitter and run the ENTIRE set of (4, 6, or 8) fans running at the same speed and controlled by 1 channel of the fan controller.

If you look around, there are larger as well, but this is just an example. I had a fan controller that did 30W per channel, if I remember correctly, which can handle a whole bunch of fans. I am not sure if they make an 8 port, but if they did, you could plug 8 fans into this device, and then this device into 1 of the fan controller ports. I made a custom length cable which is just a 3 pin fan connector at each side to plug it in. With this setup, you can control the fan speed of one rad with one fan controller port. If they don't make an 8, you can do dual 4s per rad and each switch on the controller would do 4 of the fans.

If there is an easier way, I am not sure what it is, and this worked well for me.
repped! And thank you all for your input.

Might I suggest that you repeat your question in the Water Cooling sub-forum? This has to be a reasonably common concern among the waterheads and they might have insights we airheads miss.

i am planning a build that is going to have a tripple rad and a dual rad, i saw this in this video. i dont know where to get it right now, but i imagine it is goingto be released soon.

on my build i am going to want all the rad fans controlled by PWM ( i am going to be using NF-F12s on the all the rads ) so my question was how do i control 10 fans by a PWM signal... this i believe is the solution...

fast forward to 2:18

off each header, you can put a PWM Y splitter to control more fans from each lane...

Thankyou my friend I will have a look when I get a chance. I just wish Noctuas came in black.

and control 2 fan with each channel with your current fan controller
post #20 of 30
Right now I have only like 12 or something fans installed into one fan controller.

Using this on the bottom 240 rad http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=34_289&products_id=29225

And this on the top 360 rad in push/pull http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=34_289&products_id=28845
