Well, IMO, any airflow is better than none. I don't even have room for an intake anymore, especially since the cheap cage broke off.
I have one exhaust and an Enermax Whisper 431W PSU. That exhaust is a 80mm Panaflow, rated at 21dba and 24cfm, and it was cheap, too! Also, I got another and retrofitted it to my heatsink. So, my system is very quiet.
It's pretty hot in here, yet I haven't had any stability issues. My uptime: 9 days and counting. I even play CS for hours at a time, without a hitch.
