Whenever I play a clip from youtube or dailymotion on my MB CD 1,83GHz, the fans come up after about 30s and make so much noise that I have to turn up the volume to understand what's being said in the clip. To my surprise, this is not the case on my MBP C2D that arrived here today! As my MBP has an unevenly lit, grainy, cheap screen I'm thinking about going back to a MB C2D. Now my question to the MB C2D owners on this forum: can you play a 2 or 3 minute youtube clip without your computer "preparing for takeoff"? Thanks for your help.
