There should be at least an empty bay between your CD-RW and CD drive, and possible extra fan should be used to avoid heat problem. If you can feel the heat from CD drive when it crash, it is heat problem. I have seen a true story about how a CD-RW burned itself because the user mounted CD-RW and CD drive next each other. About two years ago, I had heat problem (when play games, very similar to your situation - I ran a game for 4 hours, I almost burned the CD), now I have left a 5" bay open (I removed the cover), and have an extra case fan.
