[CUBE] Installed Fan in my cube

The peltier is a thermocouple just instead of using the voltage it 
creates with temp diff between the joints you pump DC into it and it 
can heat or cool depending on polarity. The peltier coolers are 
actually tons of thermocouples tiny ones packed together. They are way 
cool i play with mine all the time but as i said before they consume 
way too much juice and you need very big fins on the hot side to keep 
them cool.
