I just got Gears of War Triple Pack not even an hour ago, and put Gears of War 2 in. Once I've played the game after about 20 minutes, I go up to my console and hear a weird clicking noise. (like on a computer when it's processing stuff, that type of clicking noise) I looked at the disc thinking that there might be damage to it, but the disc is perfectly fine. I'm installing the game now to try to avoid this problem.
My fan was also running on a very high level (highest I've ever seen it except for Red Dead Redemption) and the noise was coming from that general area, near the hard drive.
Is this a major issue, or am I just fine? If the heat doesn't go away from my console, I'll put one of my cooling fans I got from the store onto it.
