Hey guys.

I'm going to make this quick and short.

I have an NZXT Lexa S case and when i first built my PC the fans were run through molex connectors making them go 100 % all the time.

After alot of loud noise i wanted to change that, now i saw this video:

And i realized that i should have plugged my fans into those 1 and 2 sockets.

So i did that and after that,the fans were not even spinning ?!
I tried using the knobs on the front panel but nothing.

So i saw an empty molex connector which was labeled FAN CONTROLLER and i plugged it in, and now the fans are working again, but with the same problem.

No matter how much I turn the knobs the fans are still running at 100% and if you look at the video above there IS a difference.

So can anyone help me figure out what the problem is ?

Also the molex have been disconnected incase your wondering that is the problem.

Thanks.

1)4 stock fans (1 front, 1 top, 1 rear and 1 side)
I have the first three plugged in

2) I don't quite get it what you want to ask but, there are small connectors labeled 1 and 2 (1 for top and rear, 2 for front and side), i connected them through there, also both of those small connectors go directly to fan controller knobs.

3) Yes.

Just to double check...
I presume you DID NOT also connect the fans' Molex connectors to any power source. They have to remain disconnected. Just the small connectors get connected.

I also presume you connected the fans to these white connectors and this Molex to the PSU: http://www.techpowerup.com/reviews/NZXT/Lexa_S/images/innerfanconnect.jpg
Not this Molex: http://www.techpowerup.com/reviews/NZXT/Lexa_S/images/innercaseconnect.jpg

If all the above is true, then it appears you have have a defective fan controller.

I will check if i connected some of them to molex, and yes all of the above is true that i connected to the white ones, but before i rebuilt my PC, the fan controller was working great, so i dont know what is the problem.
