The Kama-Meter Multi-Functional Controller mounts like a standard optical drive and requires one free 5.25" drive bay. Once the unit has been secured using the mounting screws, there are several additional connections that need to be made in order to make the unit functional. Consumers need to attach each of the temperature probe cables as well fan extension cables for each of the fan channels. Finally the last step is to attach the audio cable to any source card and power cable to any free 4-pin Molex connector.
