Recommend me a fan controller

post #1 of 9
Thread Starter 
I'm currently looking at this fan controller for use with 6 of these fans.
I plan to have 3 fans daisy chained to channel 1, and the other 3 fans daisy chained to channel 2.
(Each channel on the fan controller can take a max of 6W so it should be fine)

An alternative fan controller that I've been considering is this one.

My knowledge about fan control is pretty sketchy, so please answer the following for me:

First off, will these controllers even work?
What is PWM and what role does it play in fan controllers?
How can I determine if my fans will work with a fan controller?

Those fans each take 4.2 W, you can only have one of those per channel on that NZXT controller, Lamptron can handle even all six fans on one channel.

Shiz, you're right. I guess I'll have to go with the Lamptron.

Will it work though? I've read on some places that certain fans just don't work with certain fan controllers?
(iirc it has something to do with differences between voltage resistance control and PWM control)

I'm using the FC5V2 in a similar setup. I don't know how the CM fan leads are setup. On my Yates, they have a 3 pin and two 4 pin per fan, in order to chain them together. Basically I connect a 3-pin extension from the fan controller to one of the 3 pin fan connections, then use it's 4 pin molex to chain to the third fan. This gives me full voltage control across the fans, plus RPM on one of the fans in the set. Do the same for the next set of 3 fans

Not sure what you did there with the molex. But so long as it's working, that's great.

How do you like the FC5V2? How is the range of voltage control? When you turn the dial down, do the LEDs also dim?

This is what I'm planning on doing:

Unless I can find a 3-way 3 pin splitter

That'll work, just may need to disconnect or snip two of the yellow leads. If you have all 3 fans reporting their RPM to the controller, it will report 0 in my experience. I also had an issue when using only the 3 pin connectors, where there was a voltage drop using a parallel "splitter", but that may have been an issue with the PCB splitter. Other than that, it's been a great controller so far. Even powers my 1+amp Delta fan

So would it work if I used the PCB splitter but cut off all the RPM wires except one?
post #9 of 9
I have no idea if that was my issue or not. I was definitely getting about 1/3rd the voltage I should have been, meaning the 1400 rpm fans were only spinning at about 450. Very quiet, but 0 air flow through the radiator.

If you do get the PCBs, you will need female to female adapters. I'd recommend just picking up the splitters coolhandluke mentioned to save potential headache later.
