Resumo


This paper compares the cooling-efficiency between air and immersion cooling methods through the implementation of an experimental framework. Short and long term stresses with and without overclocking were run and monitored on 8 identical HPC servers. A statistical analysis using the Mann-Whitney method was conducted to determine whether or not, the temperature differences observed between the servers cooled by immersion and the ones cooled by air were significant. The results were promising with immersion cooling achieving better overall cooling performance with low energy consumption as no cooling units were used for the immersion cooling system. A discussion on practical issues encountered using the immersion technology is also included.
