In special operating conditions, for example at minimum speed over a wide temperature range, also in conjunction with a special operating circuit, a DC ventilator is intended to convey air more intensively with increasing temperature. According to the invention, a simple, operationally reliable circuit is proposed for this purpose, which can optionally be used for additional purposes and operates in conjunction with a temperature-dependent resistor element. It is also matched to a specially designed drive motor of the ventilator. <IMAGE>
