A method for using the waste heat of a computer system with a plurality of processors comprises the following steps. Jobs in the computer system are distributed to the processors in such a way that processors of a first group of processors are operated with a high processor load and processors of a second group of processors are operated with only a minimal processor load. In another method, waste heat is dissipated from the processors by a cooling device, wherein the waste heat dissipated from the processors is regulated in such a way that the processor assumes a temperature that is greater than a given minimum temperature. In both cases, the waste heat of the processors is transferred to a device for using the waste heat.
