You know when your PC suddenly has to do something, the fans speed up and it produces a higher pitched ''WWHRRRR'' noise? I imagine by having multiple fans that he can control with a certain speed he can create low and high pitched WHRRRRRRRRRRR's which in turn allow him to ''communicate'' though I don't think anyone would understand him haha.

Also, I had a question, are there 'slums' so to say?
