i have upgraded my pc this summer and i have 3 12cm fan, i need a fan controler , a friend suggested to make it out of scrach but i don't want to get in that stuff again, i want to buy a premade fan controler , anyone know where i can find it ??

You could check out with ROG store he can order you one. But is it necessary? are your fans noisy?
I will doo it too, but i will make it from scratch.

they arn't noisy per-say but they arn't silent, and i want them silent,
i am going to reduce their speeds while surfing the web then increase them when gaming

It's just a potentiometer, I think, with a special plug, no?
I used to have some, and I'm not using them anymore. Just round knobs, with the proper connector for the PC. Do you want one? I'll see where I put them. Or are you trying to find some electronic controller?
I am not using these anymore because I plug the fans in the motherboard, and can set their speed using speedfan. Can't you do that?

I was desperate for a fan controller too, but you know what? If you have your case cooling balanced, it is inefficient to control each on its own. So you would probably want to control all the fans at once. What you can do is the following:
Connect the fans to the motherboard.
If you don't have enough fan headers on the board, you can use splitters that take current to both fans but cannot report more than 1 fan's RPM.
If your fans are 4 pin, then you can cut the wires (12V and ground) and place them into a 3 pin female connector.
Now let's say you do have enough headers, but for example the CPU fan header only supports PWM speed control and not voltage stepping. And let's say you have a PWR fan header which only provides 100% and does not support any form of fan control. You can make yourself a splitter that takes current from one header and provides RPM reporting to that header and to a non-controllable fan header. I have 5 scythe fans in my case, and I attached one to a fan header, and the other pairs to a single header for current, since I only have 3 controllable fan headers.
EDIT: as rolf said, you can control them using speedfan. I forgot to mention that. Though it has to support your board's fan controller, which it most probably does. You have to configure it too. Usually it doesn't work by default.

Are these things generally in demand ? if so i think we can design something.

The case fans operates with maximum speed at 12v, and as you decrease the voltage its speed will decrease... so you can connect a fan (or multiple fans connected in parallel) to a variable AC-to-DC adapter which is connected to an external AC power source (preferably the UPS).
This adapter costs 5000 L.L and found in most stores...

The old ATARI (family game /NES) adaptor :P.
Man i burned alot of these bad boys :)...

i can with only my front fan
nothing effects my rear fan for some reason and as for my sidefan, its connected with a molex(not connected to the motherboard,since i dont have a connector)

I need someone to describe his dream fan controller so i can design it .

it should be touchscrean and you should be able to change the colors , it should have an equalizer for sound >:D

Spot on! How about it also being modular? Meaning you can add more fan headers and channels when you wish to do so, and the software would support them.
It should also have RPM reporting for each fan and an alarm system that notifies us when a fan fails or slows down.

EXACTLY!!!!
you and I thing the same ;)

@ Jad you can do two desigs for us...
1. Is that it will get the job done. this should be simple design that fits in the drive bays, under our dvds, in which we have swtiches that turns our fans up and down at the same time. It should hold up to 6 fans minimum. (colored black, and controled manually)
2. Is a more "flashy" fan controler. Black with a screen in the middle that shows the rpm of each fan, and again we can control the fans separatly. (Black with multi colored screen, software and hardware)

okay guys, lets see who wants fan controllers here so i can check out the demand. i will not do a single unit as it would cost a single person too much.
if your computers have serial ports we can have the controller communicate data to the computer, and you can control the fans using a program on your computer.
we can do upto 6 fans, each controlled indevidually by a tiny potentiometer.
i can design it so i can feed the fans with predetermined PWM signal over their signal line or over the power lines.
Beej
How much cost are we talking about? Because I am broke
shant
i made my own fan controller, but doesn't fit in 5.25 bays, its a small board in my case, it is 1 channel, its not pwm, reduces voltages, max output is 10.50volts...if anyone can tighten things up he can fit around 4 channels on 1 small board

not powerful enough to handle many fans, have you ever measured these with a volt meter?
12 volt gives you like 19 volt, 9=12-13 or something and 7 volt gives you like 9 volts, they are really really bad lol

Yes but those voltages are measured with zero load. A considerable load will take it close to 12V.

Guys, J4D here is willing to make fan controllers. If you want one, he'll fill you in on the details. A fan controller (J4D edition) will soon be on display hopefully @ ROG Store.
