anyone have thoughts on what it does to a CPU running @ 90% for 6 hours straight? I usually buy about 2-3 movies a week when they come out. rip then convert them for storage on an external drive for playback on a 360. a normal DVD rip varies from 60-90% typically at about 75-80% (2-3 hours). Since testing out a few of my HD DVDs it is more like 70-100% and usually hovers around 85-90% (4-6 hours) during recode. again i only get a few movies a week so it is not everyday. Am i shortening the life of that CPU? It is in a nice cool basement, ventilated and usually at about 60 degrees.
