This article is about the air conditioner that can be made from a computer fan.

The fan blows the air out of the plastic box filled with ice to cool the ambient temperature.

I thought of this idea when my brother found a few old computer fans on the street soaking in the rain.

Step 1: Design the Fan

This idea is not new and there are a number of videos on YouTube.

My design does not include the lid. You might need this if you are putting your fan in your car because the car could me moving on a rocky or bumpy road turning inside contents upside down. You can try using food containers with the lid to avoid this problem.

Step 2: Make the Fan

The first thought that comes to mind is which way I attach the fan to the plastic container. One side is sucking air in and the other side is blowing the air out.

We all know that if we put a hand near the computer fan at the back of a typical desktop PC we will feel a blow of air, flowing out of the computer. This is why there is no need to connect the fan to the 12 V battery before attaching this component to the plastic package. We know what the back of the computer fans looks like:
