Abstract: Examples herein relate to cooling systems. In one example, a cooling system comprises a plurality of adjacent fan modules configured to generate a plurality of cooling flows, a fan cage having a central axis adapted to contain the plurality of adjacent fan modules, the fan cage comprising a cavity on its central axis. Furthermore, the system comprises a first support bracket adapted to support the fan cage such that the fan cage rotates on its central axis and a bush established in the cavity of the fan cage. A first end of the bush is adapted to engage the first support bracket on a first surface of the fan cage.
