1. A fan for a lighting device of a motor vehicle, the fan comprising:
a frame;
an impeller rotatably mounted on the frame; and
a housing mountable on the lighting device;
wherein the frame is form-lockingly fastened to the housing,
wherein the housing includes a plurality of compliance elements which are in preloaded contact with the frame and which damp vibrations of the frame along three spatial axes (X, Y, Z), wherein the three spatial axes (X, Y, Z) are oriented mutually perpendicular to one another,
wherein a first axis (X) and a second axis (Y) lay in a plane perpendicular to a rotation axis (R) of the impeller, and wherein a third axis (Z) lays parallel to the rotation axis (R),
wherein a first compliance element of the plurality of compliance elements yields compliance along the first axis (X), the first compliance element including an arc-shaped rack split into two halves by a gap positioned and located proximate to an apex of the arc-shaped rack such that the two halves are bendable, wherein the frame is in contact with the first compliance element proximate to the apex.
