While I agree it is a rather unaesthetic color scheme, it is a case fan that prides itself on being silent and high quality. I can only assume unseen goes along with unheard.

I am buying this little fan for moving air in my basement. I will plug it into a wall socket. Do I need to have an AC-to-DC adapter?

Yes, you will need an AC-to-DC adapter to plug the fan into a wall socket, as the fan operates on 12V DC from a 3-pin connector.
