With fan controllers do the fans connect to the motherboard still or do they connect to the fan controller? Would this still be the case with the corsair graphite 600t?
 
Solution
Motherboard fan controllers are built in to the motherboard; you use software from the motherboard site to control the fans.

External fan controllers with knobs connect to the fans; there's no motherboard connection except possibly USB so you can manage by software. Depends on the controller.

The Corsair Graphite 600T is a case. The fans can be controlled by most motherboards.

*Fans are either Voltage or PWM. My Asus motherboard can control only PWM fans for the CPU, but it can control either Voltage or PWM fans via the fan connections on the motherboard.

Example:
1) Connect Case Fan to FAN_1 (case fan) connection on motherboard
2) Ensure BIOS has fan control enabled
3) Download and run fan control software from motherboard site...

Other:
I believe the Corsair water-coolers for CPU's like the H80i etc use a USB connection to manage the fan profile with no requirement for the motherboard CPU fan connector.

Well there are a couple of different types of fan controllers.

The most common type take all input away from the motherboard. You plug the fan controller into power, and the fans into the controller, and control voltage with sliders or knobs. (Some new ones have touchscreens)

Some fan controllers run cables back out to the motherboard with signal wires only to plug into the motherboard. This lets you monitor the RPM of the fans through various software programs.

There are a few USB based fan controllers that will directly control fans that are plugged into your motherboard. These are usually quite expensive and don't work with all models.

Video for building a PC with 600T case. Removed the top fan to use the Corsair H100 (dual fan) CPU liquid cooler.

*Personally, I wouldn't by any addon fan controllers. The motherboard alone can often do everything you need. Some cases also have built-in controllers and the Corsair H-series liquid CPU coolers are self-contained as well. I'd recommend using AUTOMATIC FAN CONTROL anywhere that's possible. Don't use MANUAL fan control. Why bother this can be automated. Here's how MY SYSTEM is setup:
1) 2xCPU PWM FANS
(CPU and CPU optional on MOTHERBOARD. Fan PROFILE with Asus Thermal Radar software)

2) 3x CASE FANS (PWM)
- Asus Thermal Radar Software
- 2x intake
- 1x exhaust (near CPU)

3) Graphics Card (built-in)

4) Power Supply (built-in)
