1. A support frame for a ventilation device for cooling a fluid passing through a cooling circuit of a motor vehicle, said frame comprising:
an opening defining an opening perimeter, the opening being configured to receive an impeller; and
a central support positioned at the center of said opening and shaped so as to receive a motor actuating said impeller so as to generate a ventilation flow,
said central support being attached, through said opening, to the frame by at least six holding arms, at least three first holding arms of the at least six being placed in a first cone of revolution, and at least three second holding arms of the at least six being placed in a second cone of revolution, different from the first cone of revolution,
the first holding arms each being separated from any second holding arm at the opening perimeter by a space covering at least a distance corresponding to a chord of said first holding arms,
wherein the first holding arms are placed in the first cone of revolution and the second holding arms are placed in the second cone of revolution, different from the first cone of revolution.
