All of the parts are on the way here (should be here Tuesday) for my new build. I was reading over the manual that I downloaded from ASUS website for my new motherboard, and noticed that the CPU fan connection on the MOBO is a 4-pin. The CPU cooler I'm getting (Thermaltake Spin-Q VT) has a 3-pin connection. While it looks like it should hook up without any problems, I'm curious as to the difference between the 4-pin & 3-pin fan connection. Is the fourth pin to control the speed of the fan? Is it for a heat sensor? Just curious as to what I might miss out on, and if there may be any problems associated.

It'll be fine. The 4th pin is usually for dynamic fan control, however many Asus boards use their own technology that can throttle the fan speed regardless of how pins it's connected to.
