Need science refresher

So I was in Sears at the super clearance table and picked up a few USB-connect items. I was able to resist the disco ball because the last box was opened, but I picked up a mini-shredder and mini-refrigerator. They were never worth $40, but for $4 I wanted to try them.

The mini-shredder is fairly straightforward, but the mini-fridge has me puzzled. It a small plastic fridge about 8x4x3 inches. Inside is an led and a cutout for a can bottom. The cutout places the can on a solid aluminum or stainless steel heat sink that has been honeycombed. A small cooling fan at the bottom circulates room temperature air through the chambers. There is no coolant; it is all air cooled. How much cooler can this make a can of soda or beer than the ambient room temperature?
