Whats the best way to connect multiple fans and have them pushed to 100%? Should I just connect it straight to the psu or should I use a fan controller?

You don't want to push fans to 100% unless you have a reason to.

But if you insist, directly from the PSU.

How would I exactly splice the wires and is their a limit to how many fans I can connect?

That picture is correct, except they cut the yellow wire which is 12V. If you want the fans running at full speed, they need that connected instead of the 5V red wire (don't connect both). As far as how many you can connect, assuming each fan takes up 0.6A @ 12V, with the specification being 11A maximum ( https://en.wikipedia.org/wiki/Molex_con ... nnector.29 ), you can fit about 20-22.

I've read that the yellow wire was the rpm controller?

That's not a fan that plugs into the PSU then. That's a fan that plugs into motherboard headers. That I'm not sure how many you can plug in at once.

I see, I currently have 16 Corsair AF120mm Red LED fans and Im trying to have it wired and look clean compared to using a 2x3pin split to 1x3pin to a molex connector.

Well, in your case, then yes, it'd be better to get a fan controller. But you'll need at least 3, most only have 5-6 channels.

So with that type of fan I would have to connect it to a fan controller instead of directly to the psu?

Also whats your thoughts of water cooling with koolance/xspc?

Well I do have a the molex to 3 pin connector, so can I just replace the 3 pin male adapter and solder all of 2-4 of them to it?
