I'm at work now, but the last time I checked my temp idle was around 40 @ stock speeds. I removed all my passive coolers on NB/SB and replaced with AS5 before I even powered my new build. I also have a Schyth CPU cooler. I was a little dissapointed to see my temps in the 40's, but I have given it some time for the AS5 to burn in since last I checked. I will recheck what my temps are when I get home to see how I'm doing now. As far as I can tell our temps are in line with what everyone else is reporting on these Asus boards.
I have played with my FSB a little, but yet to do any "real" o/c'ing. I run all my games at highest setting at 1920x1080 and get around 70-100+FPS. No real need for me to o/c yet since my components at stock handle anything I throw at em. Nice to know I got some good head room to expand when some more demanding game titles come out in the future.
Overall extremly satisfied with my new build.
