I wanted to find out what cooler was the best, and how to make it even better. As a result of testing, i found that liquid cooling was the most efficient way to cool a CPU. I improved upon this by trying out different kinds of coolant as well as adding other parts that helped dissipate heat faster. This included a 360mm radiator, larger tubing for more coolant to pass through, and different kinds of coolant. For this part, I tried different kinds of household coolant to see if any common fluids could possibly carry heat better than commercial fluids.Through doing this experiment, I found out that liquid cooling triumphs over metal coolers and is the type that performs the best, and that for easily enhancing this specific type of cooler’s potential, using antifreeze as a coolant as well as increasing the radiator size will give a CPU the capabilities to run under very favorable temperatures. The hypothesis of liquid being better was correct, but the second one of sports drink being more thermally conductive was rejected by my findings, because of the conductivity of antifreeze being higher and performing better than all other tested household coolants. One limitation was the fact that I couldn’t get my hands on any experimental nanofluid, which claims to be very thermally conductive (basically liquid metal) as it had the potential to beat antifreeze in terms of temperatures and desirable properties.
