Help with fan controller

pcperson7 · May 13, 2013

As of now, My build includes a three radiators, a 420, a 140, and a 120, I want to run all of them in push/pull and have one controller for the 420 and one for the 120/140- but after research I am confused about 'channels' and also how would you add two fans two the same channel?

Can someone clarify? Pictures would be an added bonus

Thanks!

they make splitters. though depending on the fans you are using you can put quite a few on each channel. I use the lamptron touch, and have 11 fans on it and using the temp sensors to control speed

Kewl, is there one for pwm fans?

But are there any CABLES for pwm fans?

what do you mean cables? I gave you a link to pwm fan splitters if that is what you are talking about

Please please please - do the math before you buy a controller and burn it up.

Volts x Amps = Watts. Make sure you allow room for startup pull of fans too.
Example: a .18amp fan at 12v pulls 2.16watts, but can pull 2.7-3.1watts at startup. So on a 10watt channel no more than 2-3 fans

I agree with buzz 100% I always recommend high watt channels

But that was a cintroller not cables!

There seems to be some confusion for you on the pwm function. You don't use a splitter for pwm. The controller connects to the header, and pwm the controls fans thru controller. Or, you click the button on the front under a channel to put in manual mode. Read that description carefully.

Your case fans can be linked using splitters to control more than one per channel. Use a plain old 3pin splitter. No pwm splitter is ever used.

the 2nd post form top ( my first post ) has a link from amazon for sleeved cables ( pwm splitters )

Buzz: I posted this right after you made your comment and I agree he seems confused on that. pwm splitters will not be needed when they are connected to a fan controller that is pwm controlled ( though I have no experience with pwm fan controllers and did not know if the pwm signal worked as a pass through )

The link you posted is a 3pin fan splitter with +, -, and rpm sensor. Standard fan connection. A pwm headerhas 4 wires. A 3wire fan can be cconnected to a pwm header, and a pwm fan can be connected to a 3wire header.

Pwm control from mobo is designed for one device control. The sunbeam controller linked allows that one connection to be mimic for up to 6 channels. Pwm is based on voltage percentage control rathrr than rpm control. Pwm lets a microprocessor control based on sensor variables
