Duron 600@950 on an A7V.
Runs between 41C idle and 48C after hours of gaming.
4 case fans (front air in, side air in, 2 back air out)
2 fans on the power supply (one on the bottom right over the processor, nice!)
1 video card fan
1 cpu heatsink/fan (GlobalWin FOP32)
Guy at work, using fan that came in the AMD processor box and he runs a 750 TBird at about 66C idle, who knows what it gets to after doing heavy work. But he never has problems with stability.
