I'm not an overclocker by any means. I just want my case to be halfway quiet, but cool the cpu well. I currently have one fan, but will swap out the fan with (maybe) the Vantec Stealth (any suggestions on fans?) and how many should I use? 1 or 2? I will be running Athlon XP 1900+ ASUS A7V333 512 Megs Samsung DDR Enermax 350 W Dual Fan Power Supply Suggestions?
