fan controller to controll 2 fans!!

[up2nogooduk]

Hi,

I just got a Scythe Kaze Master Ace fan controller i have 6 fans.
I need to be run 2 Apache Black Super Silent 120Fans - 4 Pin- at the same time. and another 2 at the same time. but the problem i got, is the i cant find a 4pin splitter, as the Apache fans have 4 pins and not 3, so i can't use the 3 pin fan splitter shown here http://www.overclockers.co.uk/showproduct.php?prodid=CB-013-AK.

Is there a way round this?

Thanks for your help

What about the PWM splitter?

Provided you have a PWM source you can use that to control the fans.

For your own PWM source you'd need to get a fan controller that can do PWM output or build your own.

Failing that you could just control them by DC voltage like normal fans. The 4 pin will fit on an unshrouded 3 pin connector or a 4 pin shrouded with a bit of the plastic removed.

I used a 3 pin fan splitter same as your link and just cut off a bit of the plastic so the 4 pin would fit, as it was running through a fan controller wasn't to worried about loosing pmw.

Hi thanks for the help guys..
Noob Question sorry!! lol
What do you mean by PMW. and if i'm not using the PMW with the fans, what difference does this make?

But yes if ok i break the plastic off on my fan splitters then

Cheers

As far as I understand it, PWM is "Pulse Width Modulation" which is basically a 'throbbing' signal sent via the motherboard header that dictates to the fan how fast it should spin (relative to CPU temperature in this case)

When you're using a fan controller, you don't need the PWM signal as the motherboard is no longer controlling the fan speed... the fan controller is

So IMO the best option there is chopping a bit of plastic off the side of the 3-pin splitter to fit the wider plug in

or using the PWM splitter isn't a bad idea either... saves any wanton destruction lol

you could always get two of these:

and plug them in like this:
i am not 100% sure if this will work, but i see no reason why it shouldnt

(sorry for the crap drawing, but i think you see what im getting at)
F# = fan#
M# = molex (power) number
different colours represent each separate cable

if you are short on 4 pin molex cables you could easily get a 4 pin molex splitter, as the molex could probably power 100 fans if you really wanted it to:

@above poster:
your right, PWM = pulse width modulation. in simple terms, the power to the fan will be turned on and off very quickly, and the length that the power is on compared to the length that the fan is off will change, changing the overall power the fan gets. obviously this will change the fans speed
