I had a old phat PS3 before and recently got the new Slim with the InFamous 2 bundle. Seems to run fine, but when I put in a DVD, it makes a loud fan like noise for maybe 3-5 seconds and then quiets down and runs fine. It doesn't seem like a big issue, but i don't want to take a chance. So is this somewhat normal? Seems to happen only with DVDs, some DVDs. Have not had this problem with any games.
