Pumpkin,
Unlike water, Air (fan cooling) is a very bad conductor of heat. For example, that's why new houses have two layers of glass with air in between to keep the inside and outside insulated.
On the other hand, that is why everything today that needs to be kept at an exact temperature is liquid cooled from computers to Harley Davidsons, and even snowmobiles. Water is a much better medium for heat transfer and it is also much easier to precisely control.
When did they stop making air cooled Volkswagons?
In addition, water also conducts sound much better than air, but that's not pertinent to this topic. |
