As two liquids were applied (i) water and (ii) copper oxide (II) nanofluids 0.0086 and 0.0225 volume fractions. In the experiments the commercial heat sink was fixed to the CPU. Maximal power dissipated by investigated processor was 115 W. Mass flow rate of the investigated liquids was in the range of 0.009 to 0.05 kg/s and the inlet temperatures was in the range of 300 to 305 K. The experimental results were used for validation of numerical model of the analyzed system. For simulation of the heat transfer the commercial CFD package ANSYS Fluent 13 was employed. The laminar flow regime was considered in a fin array area of the investigated heat sink. The model with a good grid quality was developed and validated. The obtained results prove that for CPU cooling water is good enough.
