Fan guard configured to selectively cover aperture

A computing system comprising:

• a fan system including:
• a fan module including:
• a housing configured to retain a fan and a motor to rotate the fan, the housing including:
• an air inlet aperture on an air inlet side of the housing;
• and
• an air outlet aperture on an air outlet side of the housing;
• and
• an outlet fan guard coupled to the fan module on the air outlet side of the housing, the outlet fan guard including:
• at least one flap rotatable between a closed position, covering the air outlet aperture of the housing, and an open position, uncovering the air outlet aperture of the housing;
• and
• at least one spring urging the at least one flap into the closed position;
• and
• a chassis including a fan cage configured to retain the fan system,
• wherein the fan cage includes a projection, the at least one flap includes a flange, and the projection is configured to cause the at least one flap to:
• rotate from the closed position to the open position during insertion of the fan system into the fan cage;
• and
• maintain the at least one flap in the open position with the fan system retained within the fan cage.
