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.
