Fan Powering

[Mentize]

Im currently in discussion with myself where to physically plug all my fans in to, there's a variety of options and figured i'd come here to ask for a more experienced opinion on the issue:

--Have included a diagram just because its makes this explanation so much simpler--

Note That the middle Hard drive cage is completely removed, giving Front Intake 1 unobstructed airflow
Note That a Corsair H60 is being used in this build (Hence the Pump)

Top Exhaust 1 - Top Mounted 140mm Exhaust Fan
Top Exhaust 2 - Top Mounted 140mm Exhaust Fan
Rear Pull - Rear Mounted 120mm Fan, Pulling Air Through the H60 Radiator
Rear Push - Mounted on the Inside of the Radiator, Pushing Air Through the H60 Radiator
CPU Pump - The Power for the Water Pump of the H60
Side Intake - Side Panel 140mm Intake
Front Intake 1 - Front 120mm Intake
Front Intake 2 - Front 120mm Intake

I have the following options for powering these 8 units:
4 Chassis Fan Headers on the Motherboard (Which I'll probably allow Asus AI Suite to control) (Asus z77 Sabertooth)
1 CPU Header on the Motherboard
1 CPU Assist on the Motherboard
3 Headers for the built-in fan controller on the case
Power Supply Unit (Corsair AX750)

Need help deciding where to power all of this from, to keep optimum cooling really, but having a bit of control over the noise never hurts for late-night gaming -all suggestions are welcome!

Isn't it Asus that only allows PWM fan control of its motherboard headers? Just saying as some case fans are 3 pin and won't work like you want, not without some clever converter

Yeah its an Asus motherboard, if that's what your asking? im new to the system building and this is the one of the issues I'd like some experienced advice on :s
all the fans are 3-pin aswell

I think it Asus that has this issue.

Your attached fan controller could probably deal with a few fans but ultimately it'll be limited to the amount you could attach.

A separate fan controller might be the order of the day.

You could also look at using PWM fans via the motherboard.

Yeah, i agree with that, but upgrades are out of the question for about a year now given how much i spent getting all this together, the integrated fan controller can only handle 3 by the looks of it.

At the moment i'm thinking the following:
Attach Top exhaust 2 & Front Intake 2 & Side Panel to the Fan Controller,
Attach the Pump & Rear Push to the CPU Header and CPU Assist header,
Attach Top Exhaust 1 & Front Intake 1 & Rear Pull to the motherboard headers,


All the fans are Bitfenix Spectre Pro's btw
--Not sure whether to plug the water pump directly in to the PSU though, probably won't happen but is an idea i had--

I would not use the top vent fans... and would remove all unused PCI slot covers.

Three intake fans should push the hot air from GPU out PCI slots and no top fans means no disrupt of airflow to radiator intake fan. Any extra pressure in case will flow on out the top without the need of a fan.
