Hello, I'm thinking about building a insane water-cooled build and need help answering these questions. Im thinking about doing push pull config on every radiator except one. How should I connect all 25 fans.

8 on top rad (480mm), 6 on front rad (360mm), 8 on bottom rad (480mm), and then 2 fans on the other bottom rad (240mm). I know there are fan hubs but I don't know much about them.

I appreciate your help.

Thanks
-Cam

A s*** ton of fan splitters. You could connect fans directly to your powersupply or buy a few fan hubs (the fan hub option would probably be the best option). Something like this www.amazon.co.uk/NZXT-Grid-Fan-White-LED/dp/B00D2ZK2VW/ref=sr_1_1?ie=UTF8&qid=1433790816&sr=8-1&keywords=fan+hub . just search fan hubs on you favorite shopping website and you will find some. Just look at the reviews and use your judgement to find a good one.
On the other hand, do you really need that many fans. Doing push-pull on most of the radiators might not even be necessary as you have so many radiators. Having that many fans wont help cooling. Quoting 4745454b "Agreed. 15 fans isn't a great idea. You'd probably end up with 15 pockets of air. Air cooling works by flowing air from one end to another. Not just running as many fans as you can." (http://www.tomshardware.co.uk/answers/id-2674373/connect-case-fans.html).You want to use 25, might not be the best idea.

Even that only connects 5 fans. Imagine the logistics to control fans on various radiators or even two hubs for one radiator and having the fans being efficient and coordinated.

But I usually just shake my head and move on when people have thees weird schemes in mind. :)

That's a 10 channel hub that he linked. 1 input, 10 ouputs. I have one for my 6 fan radiator, and one for the rest of my case fans. If you are no s@!t getting 25 fans, then 2-3 of these will be good. They also make multifan splitters as well.

As Alex said, it's not really needed. Unless you are running like 3 x Sli Titan build, there is no need for that many Rads/Fans. You aren't going to get below ambient temps, no matter how many rads you have. I have 1 x 360mm, and my temps rarely get over 40c... Seems like a giant waste of $$$$. If you want to throw your money at something, throw it to me and i'll put it to better use.
