Well, usually 4 pin fans are mostly used by CPU HSFs and most of the users leave the CPU cooling control to the system itself so I understand the lack of PWM control. I do have my CPU fan attached to the MFC2 (3rd fan), its a noctua, only 3 pin. I could have connected that to the mobo, but before I did I didn't know how noisy it would be. I guess even at max speed I can't hear it above the case fans.
Well, the wattage display may not be (and I'm aware of that) too reliable, but none the less it gives me an idea on how much my computer is drawing. Playing Crysis that bar will shoot off to over 550W, adding a max of the 2nd PSU is taking from the drives and other stuff (about 50w), my computer draws approximately 600W of power.
As Ducky stated Skythe Kaze master bay is also a great fan controller. I just prefered the zalman due to its design.
