Step 1: Chill the Ice Pack

Picture of Chill the Ice Pack
Chill the ice packs in the freezer compartment for over 12 hours and place them in the polystyrene ice box.

Step 2: Design the Polystyrene Ice Box

Picture of Design the Polystyrene Ice Box
On polystyrene ice box, take the top cover and  make 2 holes to accommodate hot air intake and cool air exhaust DC fans.
Left hand side of this picture is a DC fan with heatsink, drawing hot & humid air into the cold chamber and right hand side of the picture is cool air exhaust.

Step 3: Attach the Bent Copper Pipe

On CPU heat sink attach the bent copper pipe.
Having copper pipes to run icy water circulating through the aluminium heat sink while hot air is being drawn to the chilled metal surface, condensation will occur. The condensed water will then drip into the ice box filled with ice packs and water.

Step 4: Attach Aquarium Pump to Copper Pipe
