External enclosure for dvd burner



Hi, I am looking for a quiet enclosure for my dvd burner. And have the following questions:

  1. do I need to have an enclosure with active fan to house the dvd burner? Some enclosures dont come with a fan, will that shorten my dvd burner life time?
  2. Can anyone recommend a quiet enclosure? I currently have a plumax enclosure with a 4cm rear fan, it is really noisy (maybe just me, being a laptop user for 4 years, can’t stand all the noise from desktop pc anymore)
