Preliminary experimental of GPU immersion-cooling

Abstract

A typical information technology system takes around 40% of the total energy used in cooling the system. There are three major classifications of cooling system and they are: water cooling, close loop liquid cooling, and immersion cooling systems. Immersion cooling has been observed to be the latest trend in cooling systems for IT devices. It is a cooling procedure that is carried out through the immersion of all computer components in a dielectric coolant. This research examined the cooling process of GPU using this immersion method. Mineral oil, because of its high dielectric strength, is used as a medium fluid. The temperature difference between the use of fan and immersion cooling was then measured using a benchmark software. The result showed that the immersion cooling produced a lower GPU temperature compared to the conventional fan. The working temperature of the GPU with the use of immersion method was 70°C while it was 80°C with the conventional fan method.

Active and passive cooling techniques of graphical processing units in automotive applications - a review

“…The fan generates airflow, which aids in heat removal by increasing the heat transfer rate. The passage of air over the heat sink improves cooling, reducing overheating and maintaining appropriate operating temperatures, as observed in the article by Pambudi et al [48]. The design and configuration of fan cooling systems might vary.…”
