My CPU, Intel i5 3570k, is running at stock speeds with the stock cooler. When playing games, the temperatures are about 50 degrees Celsius, which I'm perfectly fine with. But when I render a video in Windows Live Movie Maker, the CPU hits full load and goes up to 70-80 degrees Celsius. Should I be concerned? I'm worried I'll burn out my CPU by rendering a video for about 30 minutes and having it sit that high for that long.
