CM Storm Trooper fan controller

[paulstung]

Has any one out there got any idea how many fans the built in fan controller, on CM S Trooper can handle. I have got 10 fans in total 6 on one rad and 4 on another, and at the mo they are all running at full whack, and it sounds like it is going to take off. They are connected through a 10 fan pcb from a Phantom, if the built in controller can't handle all of them can I connect the pcb via a 7v or even a 5v resistor, to step them all down all would I need a resistor for each fan ?

What no one ? I've googled every combination of words on this subject and have found nowt.

You can do that with the Phantoms PCB, although you don't need a resistor.

Rewire a molex extension - I'm pretty sure I've told you this before(?)

You have mate, I would just like a little bit more control over my fans. I knocked up a 7v cable as you said, but my rig won't post the fans start to spin then stop, I then bought a 7v Bitfenix molex, and it does the same. So I tried putting half of the fans on each 7v molex and still the same. If I then remove the 7v cable and re connect through 12v it comes on as it should. I can't understand why it would do that.

I tried all the fans through the controller they all work but I'm concern that any longer than testing would it be too much ?

Try watching the trooper review mate. Positive I mention it there.

I'll go and have another watch, I sat and watched the review and the whole Orca series and can't recall seeing / hearing a max fan / load mentioned.

Ahhhh amps. Theyll never run full 12v.

Ive got 6 fan on orca wired in to one 12v line with a fan speed reducer.

12v - fan speed reducer - 1 3pin to 6x 3 pin

Some power supplies won't run without a ground connection. Molex cables have 12v, ground, ground, 5v. You get 7v through the 12v and 5v difference, which your PSU obviously doesn't like doing.

You could always go for 5v instead. You shouldn't have any problems running that, as long as your fans will start at that low voltage.

I personally don't think there's any need to have control over fans like you're suggesting - especially in watercooled rigs. I have all the fans in my PC at 5v and have absolutely no temperature issues. The only fans I've found not to start at 5v have been Noctua NF-F12s, and a couple of 140mm fans.
