Abstract: A method of operating a fan control of a cooling arrangement having at least one exhaust air unit that withdraws air heated by electrical or electronic parts of a plurality of plug-in components, and having at least one cooling unit that cools air used for cooling purposes including determining a selected temperature difference for the air used for cooling the server rack relative to power consumption of the at least one exhaust air unit and the at least one cooling unit depending on the temperature difference; measuring at least one actual temperature difference between at least two temperatures of the air used for cooling purposes; and adjusting the speed of a fan for the at least one exhaust air unit depending on a deviation between the determined optimized temperature difference and the actual temperature difference measured.

Abstract: A rack housing that accommodates a plurality of fanless, plug-in components includes a plurality of plug-in positions that accommodate the plurality of fanless, plug-in components in a first region of the rack housing bordering a first housing side, at least one installation chamber that accommodates at least one add-on component with at least one fan, and at least one low-pressure chamber in a second region of the rack housing bordering the first region, wherein 1) first openings are provided between the low-pressure chamber and the plug-in positions, which openings allow a discharge of air heated by the plug-in components into the low-pressure chamber, 2) the at least one installation chamber and the at least one low-pressure chamber are essentially decoupled from each other with respect to cooling air, and 3) the installation chamber is connected to the low-pressure chamber via at least one connector for forced ventilation.

Abstract: A server device includes: electronic devices; a housing that houses the electronic devices; at least one fan; air volume control units configured to adjust a volume of cooling airflow which is generated by rotation of the at least one fan and is ventilated through the electronic devices by opening and closing of respective valves; a valve opening control unit configured to control valve opening degrees of the air volume control units so that temperatures inside the electronic devices become a given target temperature; a fan control unit configured to run the at least one fan at a fan rotating speed that achieves a volume of cooling airflow to make temperatures inside the electronic devices become the given target temperature at a valve opening degree higher than the valve opening degrees that the valve opening control unit controls.
