1. A server device, comprising:
a chassis;
a plurality of fan modules adapted to be installed in the chassis in a hot-swappable manner; and
a controller configured to reduce a fan speed of each fan module in the chassis from a target speed to a first temporary speed in response to a fan module insertion event, and then to increase the fan speed of each fan module to the target speed after a first predetermined time elapses,
wherein after the fan speed of each fan module is increased from the first temporary speed to the target speed, the controller reduces the fan speed of each fan module from the target speed to a second temporary speed that is less than the first temporary speed in response to detection of at least one of the fan modules not running normally, and then increases the fan speed of each fan module from the second temporary speed to the target speed after a second predetermined time elapses, wherein the second predetermined time is longer than the first predetermined time.
