My current AMD 64 rig, thats in my sig is running at about 49-51C Idle, now the room its in is very hot at times, but normally not above 75 Faranheit. When i clean the heatsink out it gets cooler, but i haven't had time to do that recently. Its an AMD 64 3400 @ 2.4ghz (stock) Socket 754. Now i ask you guys is 49-51C too hot for idle? Sometimes it gets up to 65C sometimes during gaming.
