I have recently built a 3ghz editing box. Last night I noticed it was running way hot. I was rendering an hours worth of footage, which was taking about two hours. The heat I felt in the fan exhaust concerned me so I pulled off the side door to the box and discovered that some of the pci cards were to hot to touch comfortably. I shut the machine down and started to work out a plan for more cooling. Is it normal for the newer faster cpu' s to run this hot? Or am I right in thinking I need more airflow? How are you people handleing your cooling? Any ideas.
