I have the budget to get the little more expensive fan controller but there is no reason in buying because I don´t require the function to regulate the fan speed anyways
That is why I chose the On/Off Fan "Controller" not to function as a "Controller" but to be used as fan medium...I could also have bought 7 Molex to power connectors instead^^ but that would come cheaper and look better with the plus that I can put 2 fans on one channel since every channel has 60 Watts
Heck I could all 7 fans on one channel^^
I think On/Off fan controllers are a good idea...we are living in a time in which the industry is concentrating more and more about sound , silent, be quiet etc etc...regulating a fan was always about noise...what other reason is their to control your fan speed? if you can have good cooling ability with 12 Volts and it is still unhearable?
I dont know anything aobut that fan..I'll bet its not anything as near as my San Ace 1011 high power fan..Witch is somthing like 0.56A to run at 12v..cant remeber what it took to start..but anyway i would have a hard time beliveing that your on off fan controller cant handle the fans your using...they are just normal fans, not high power/high RPM.

If your fans dont bother you at 12v/full RPM, then use the ON/OFF controller, I dont know what they cost or anything like that. Look into somthing like this. 6 bucks USDM+shipping and you can daisy chain them off ONE molex if need be OR mix and match the molex to 3pin, with 3pin splitters.....I used that for a temp set up untill i got the Rheosmart. To defend my Rheosmart controller, it can use the mobo's PWM header and regulate all the fan's plugged into the rheosmart based on CPU temp, allowing for a even newer era of having high powerd fanns spool up with CPU temps its not for everybody, but I love it! All methods posted in this thread thus far would work just fine..just depends on how much you want to spend on it

1.)I did find something about the fan now.

It is supposed an innovation
High flow and extremely silent^^
They are supposed to be very popular right now in terms of case fans.
http://www.bitfenix.com/global/en/pr...ectre-non-led/
High Power or RPM fans are not my thing ...I prefer a silent and smooth system
I am water cooling anyway with the Gentle Typhoon the absolute king of fans
But I like to have some nice case fans ...that are silent and low RPM is all you need....and since those fans push a lot of air at low RPM they are just perfect


2.)Yeah I will probably go for the ON/OFF controller , it is cheap , looks great , has 60 Watt per channel!! and is all I need considering the fans can not be heard at 12 Volt 1000 RPM
Also the green will fit my color theme just perfectly
I think fan controllers are not very handy anyway ...80% of people that buy them don´t use them at all ...or either have them on the highest setting or off...which equals ON/OFF anway ...and even if you have to control them what is the point?
Fans nowadays are so silent they don´t need to be controlled anyway
And if you really need it just extend your PWM Mobo header by a splitter^^

If you wire the fans in a Series you will experience a voltage drop and speed drop from fan to fan.

Wiring in Parallel you will get the same voltage to each fan because it each fan is hitting the +rail directly and experiencing no V drop from fan to fan. What is important in the Amperage of the fan and supply. You do not want to exceed the Amperage of the source by the components, it will...not be good.

@cook:thanks for the input!

But I have already decided to put the fans on a 5 channel fan ON/OFF fan controller with 60 Watts per channel.

I am sure 2 Fans can be hooked on one channel with a splitter since it has 60 watts and the fans only require 2 Watts to reach their full potential

my fans are not quiet at anything above about 65% lol. but then agin I have
San Ace 1011's(2 of them) on my cooler, and working on sporting AP-30's as case fans. All are pretty much off when the CPU temps are at idle, and ramp up as CPU temp rise's mind you the wind tunnel effect isnt for everyone, but I test G.I. Joe missle areo dynamics in my spare time

Ok guys I need a little update.

I won´t be able to get the Lamptron Fan Controller.

So I would like to rephrase my question.

Is it possible to put all 7 fans (3x140mm + 4x120mm 1000RPM) on a single 4-Pin Molex Adapter which sits directly on my PSU through a 7x3Pin to one 3Pin Splitter?

4Pin Molex:

7x3Pin to 3Pin Splitter:

I see no reason why it wouldnt work. your 4 pim molex should power a small army of fans.

So why is a simple 4 Pin Molex pinned to the PSU able to power 7 fans with the 7 to 1 3Pin Splitter but the Motherboard fan header isn´t?

Amperage of a psu 12v rail is a lot higher than off a motherboard header. The tracks on the motherboard simply cannot support the power draw, but the psu rails have decent thick wires and can support the power draw

Aha

And the fact that the 7 fans all spin at around 800 - 1000 RPM should also require less power right? Because the Wattage requirement for the motor is lower.
