It won't hurt your cdroms in any way, because it doesn't get hot enough. I've had the Pioneer 10x DVD for two years now, and my discs get warm too. CDROM's can withstand a lot of heat. Take for instance leaving your cd's in a car, while it's 90F+ outside. The interior of the car can get up to 200+. I've never had problems with my cd's going bad because of heat.
