josh you should be able to hit those speeds you're looking for, just remember thats its not all about cpu cooling, you've got to have a cool northbridge as well, and generally having good airflow helps as well (since the Mosfets on the board have an impact as well, and they get HOT). Upping the voltage that little is fine, don't worry too much about that. As for the temp range you're looking for though, I haven't had hands-on experience with the Zalman cooler but I'm not sure you'll get such "mellow" temps... nonetheless, anything under 60*C is fine (though i shouldn't be talking, i run at 29*C idle/33*C load with watercooling lol).
