In this video, I show you a new water cooler setup for my Peltier cooler experiments. Previously, I’ve been using a water-cooling kit for PCs. The biggest change is in the radiator. In the new cooling system, I use a radiator which is actually a car part, it is an oil cooler. The fittings are perfect for the hoses I already have so it is easy to match them with any PC water cooling parts (i.e. 8 mm hoses). The surface area/contour is nearly two times larger. The thickness of the unit is the same, however, the older cooler (the dedicated CPU/GPU) cooler has more dense lamellae.

The experiment suggests that this cooler has more potential, but due to the poor airflow, I could not create a significant temperature drop between the inlet and the outlet. The difference was only around 2-3°C. However, the maximum temperature of the water was around 45°C which is very nice if considering the amount of heat pumped into the system.
