It is built to cool my server cabinet (which is an Ikea Alex with some holes in it), but can also be used to cool console cabinets or anything you need cooled. +The cooler itself is based around two temperature sensors, which both control their own set of fans. This allows for two separate temperature zones, with the fans operating at different speeds. + +## Parts + +This parts list is just for the soldered-on components.
