A liquid cooling device includes a base, a housing and a heat exchanger. It is proposed that, during the increase of the fluid pressure to the predefined setpoint value, the control unit switches the fluid pump off before the fluid pressure has reached the predefined setpoint value. segments which are not complete circles and which are interleaved into a disc pack of multiple layers, wherein some layers of the disc pack each consist of a single disc segment which is less than a complete circle. The voltage transformer unit is mounted on a circuit carrier which is arranged in the casing base element in such a way that a defined first region of the circuit carrier is received in a casting space filled with an electrically insulating casting compound. Register retiming may make changes to a design at a gate level. Threads may then be dispatched to the spare processor for execution.
