Hot Netgear DGN2000

After years of being with Demon I decided to give MacAce a try. They sold me a preconfigured Netgear DGN2000. It seems ok, but runs very hot. This has made me a little nervous about leaving this router on continuously. I have looked on the web and this seems to be a bit of a problem with this model.
Does anybody have any thoughts, words of wisdom, or horror stories.
