I've been hearing about some stellar overclocks on these chips (3.5+ on stock cooling an volts) and some people even getting close to 4 ghz. My 2.8C doesn't like anything above 3.15 for consistent day-to-day use. The case is a Sonata, with the default fan and a VGA Silencer exhausting (something like 80CFM) and an SVC 100CFM windtunnel as intake, and a Zalman 7000 Al-Cu for CPU cooling. I think I'll be able to cool it down without much of a problem. I'd like to hear back from some 2.4 Pressy owners and see what they have to say and how high of an o/c they got.
