1. A cooling device for a vehicle electronic control unit (ECU) comprising:
a casing for covering the ECU, the casing comprising:
a heat absorbing face configured to absorb heat from components of the ECU; and
a heat dissipating face configured to dissipate absorbed heat from the heat absorbing face; and
a plurality of fans mounted to the heat dissipating face and arranged to direct airflow over respective regions of the heat dissipating face, the fans being independently controllable to be driven at different speeds to vary cooling of the respective regions of the heat dissipating face.
