A carrier frame ( 104 ), for installation on a circuit board ( 2 ), is implemented in the manner of an oil-drilling rig and comprises a platform ( 117 ) that is equipped with supporting legs ( 105, 106, 107, 108 ) for mounting on the circuit board ( 2 ). The carrier frame has, at the center of its platform ( 117 ), a depression ( 121, 123 ) that is implemented for installation of a fan ( 3 ) at a distance from the circuit board ( 2 ), the outer wall ( 123 ) of the depression ( 121, 123 ) forming part of the fan.
