[SOLVED] Are my fans working like they should? They are quite loud...

[seaWanderer]

I installed some Noctua 140mm fans replacing the stock fans in my Fractal Design R6 case, and although all of the 3 fans are running, the 2 in the front are quite so loud compared to the back fan, but i cannot change their speed in any way! I tried going into bios, but when i put to silent, it didn't change the speed, even after i save & quit. Actually, in bios, it shows the fans as "N/A"... I have only 3 fans (+cpu-fan) installed.

And then i downloaded SpeedFan, which shows this, so...how can i change the fan speed, especially the front fans? I am running Win7.

Well, what are the exact model Noctua fans and where are they plugged into?

Noctua A14 PWM and they are plugged into the fan-control part on the side of the case, as you can see here:

Come to think of it, the 2 front fans are connected through a Y-cable and into 1 slot... So it's 2-in-1, i guess. Maybe that's the reason, or?

No.
The center connector should be the power in connector from the psu. The bottom right connector should be connected to the motherboard, then theres 3 fan positions above that for pwm fans. You can use a splitter because the signal carries from the header, which controls all fans on the splitter equally.

But they need to go into the fan1/2/3 positions.

Right now, with no motherboard connection, all they receive is straight 12v with no 'off' signal controlling the speed.
