There are 2 fans, 1 top and 1 front fan. The top fan also acts as the cooling fan for the radiator if you opted for the liquid cooling option. Otherwise it acts as a regular exhaust fan.   Both are independently controlled from within AWCC. You can also control them with HWinfo.   AWCC fan control 
As in can you set different duty cycles for the top fan than the bottom fan, etc etc?If not whats the easiest way to do something like that?  How many fan channels are there (I believe its 3 as in bottom rear fan, top rad fan, and the one for AIO pump thats always used up if your liquid cooling?) What if you wanted to add more control channels need power supply and controller, or can use hard drive bay powers or something along that line with a add on pwm controller?
Aurora R10, can you control fans independently?
