I'm curious about temperatures as well. I'm using a Cooler Master DP5-6H11 as well and two case fans on a Duron 800 that runs 950mhz to 1ghz with voltages running between 1.7 and 1.8. Is there any particular temperature threshold I should look out for? The hottest I've had it run was 114 degrees. The system was still stable, but I'm just wondering how hot is too hot? PC Alert has 122 degrees as the mimimum threshold before it will sound an alarm. I like the extra performance, but I don't want to fry my CPU.
