Corsair 900D Fan Control Options

post #1 of 4
Thread Starter 
I have had 16 fans running in my Corsair 900D for a while through molex adapters, but they all run at max RPM and the fan noise is getting to me. Not to mention that at max RPM is completely unnecessary for dual 480 radiators, especially at idle.

I can't find an elegant way to run them all with some sort of RPM control. I have 8 in push/pull on the top 480 radiator, 4 in push on the bottom 480 radiator, 3 intake on the front for the hard drives and one exhaust on the back.

I can't find anything at all that is a simple and clean way to hook them all up and control the RPM. I am running Corsair SP120 fans, so they are not PWM. I can adjust the RPM on the motherboard headers, but with so many fans and so few headers that is not a nice way to do it.

Ideally I would like a fan controller that can be adjusted electronically via software or even with a knob that doesn't get put in a drive bay. I would like to have all the fans on a single radiator to be controlled all together if possible- so one knob for 8 on the top, one knob for 4 on the bottom, one knob for 3 on the front and 1 on the back.

Does anyone know any fan controllers that don't use a drive bay that can sit inside the system and can handle that many fans? Or one that can be controlled electronically through a USB header?

Check out the Aquacomputer Aquaero 5 LT and the Poweradjust 3.

I just have a basic rheostat controller. I have a 360 and a 480 rad with only one set of fans on each. The controller has six 30 watt each channels. So, I have fans in groups off splitters. I don't have adjustable fans on the fly, but I set them a bit bellow half speed with Corsair SP High Performance fans on the rads. Quite AF fans everywhere else. It's a low hum. When folding I get about 60C on the CPU and mid to high 30's on the Titan X cards. When the room warms up I hit 42C on the GPU's. Seems to be plenty of rad space to keep two Titan X cards and a 4930K @ 4.4Ghz happy.

If you really want more control over speeds, Aquaero is the way to go as stated above.

I ended up getting a Lamptron FC5V3. Though it doesn't have control via USB or anything like that I noticed I don't really need to adjust them. With all the fans at super low RPM (and the pumps as well) everything stays cool enough with the graphics cards maxed out. I guess that really is the point of watercooling is the quiet.

For an internal setup the AC Aquareo 5 does look pretty nice though. Not sure my 900D would have space to fit that in there hidden (ironically because its a 900D).
