I have a server rack near my office and would like to see if i can decrease the noise level. It would seem to me that the steady drone of the fans could be cancelled out to a large extent. There are rack chassis designed to reduce noise. An example are the APC NetShelter CS line. http://www.apc.com/shop/ca/en/categories/racks-and-accessories/racks-and-enclosures/netshelter-cx/_/N-1ks6cn2 I don't know of any other way to make servers quieter, though. -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education?
