Cool Coffee Cooler ... or Tea

This is machine for people who wants more from life. Its purpose is to cool coffee (and or tea) and it does is SLIGHTLY faster than normal heat transfer from higher to lower temp in normal conditions or so it seems ;). So it gives you slightly more time spared.

This is the first version and the initial project name was "Pointless machine".

The fan is 92mm diameter i used SilentiumPC Zephyr, very happy with it.

I used some old 12v 0.15a LED PSU to poweron.
