Yes, some new air coolers come with a top load ice cube tray that allows you to add icy cold water to the tank for quicker cooling. Adding ice to the tank makes the cooling pads cooler and results in cool air passing through them. However, read the manual of the air cooler carefully to understand how much ice you can add. Adding too much ice can cause the evaporation of the air cooler to slow down and hamper the efficiency of the air cooler.
