Fan splitters give full juice?

post #1 of 6
Thread Starter 
Hey. so iv'e just asked the same question about pcb splitters for fans, but ive changed my mind a little, i am now thinking about theese:

http://www.xoxide.com/y-cable-3pin-molex-60cm-black.html

it says 3pin molex to 3pins but anyways i wanna plug one-two or three fan
connectors to a fan controller and be able to controll 8-12 fans off of two three or four dimmers

but if i crank the dimmer to full will all the 6 fans get their max rpm or +-10%? smile.gif

and if so if i had 12 fans will all of those get full power by using splitters like this?



Thanks smile.gif

as long as the controller will handler the combined wattage of the fans they will get full power.

You know that by reading the specifications on the fans. they should tell you the wattage if they only tell amps then multiply amps X Volts (12) to find watts. You controller should tell you how much wattage or amps per channel on it.

example
6 AP-15 fans (gentle typhoon) at 1 watt each is 6 watts for one 360 radiator-- fan controller is good for 12 watts a channel so you could put 2 radiators one one channel..

Koolance Fan, Fan, 120x38mm, 116CFM rated at .75 amps so this is .75amps X 12volts = 9 watts


something like this biggrin.gif

Headers on the motherboard are usually good for up to two fans. If you want more than that there are splitters made that hook into a molex for power and can handle more. I have a PWM splitter I bought that handles up to 6.

You will just have to check the manual of your fan controller! The one I had, being a noob, did not support enough wattage for 10 fans running at full capacity. Most likely it will not because the voltage is specific for a reason tongue.gif
