Nowadays, cooling of electronic chips is one of the most serious challenges due to the exponential growth in the demand of increasingly powerful computer systems; the overheating of these components has become a problem of high importance. For this reason, the new cooling technologies such as liquid cooling systems replace the conventional air-cooling systems to avoid the effect of hotspots generated on a chip. To make matters worse, the current use of video games is requiring a tremendous amount of energy dissipation, over passing the cooling requirements of CPUs. Therefore, in this paper a new geometry is proposed to keep cool the graphic processor unit (GPU) in a CPU, using water as the working fluid. The main aim of the design is to enhance the heat dissipation in the GPU, decrease the pressure drop during the cooling process and reduce the amount of material used to build the waterblock. A numerical simulation solves the energy and momentum equations. The thermal performance of the proposed geometry is compared with a commercial heat sink geometry previously characterized. The results for the new geometry show that greater heat dissipation is not reached (results are about the same as the results for the commercial geometry) but due to the modification made, there is less pressure drop, while reducing the size of the waterblock. These results make this new geometry quite a good candidate for the new state of the art of cooling waterblocks.
