Abstract
A processor in a multi-node system includes a detecting module which obtains temperatures of all nodes periodically. A comparing module compares all obtained temperatures to obtain a greatest temperature. A determining module determines a fan speed value corresponding to the greatest temperature according to a predetermined table which records relationships of temperatures and fan speed values. A control module controls all fans to work at the fan speed value corresponding to the greatest temperature.
