This is the main chiller unit, Igloo says it can chill 40 cans or 4 liters of liquid up to 40 degree below ambient temperature. The bottom larger sink is the hot side and top is the cool side. there is a large solid aluminum block that serves as a thermal pipe to move the heat from the cool side to the hot side . since the block is very thick i can insulate the area where the beverages will be. The Peltier unit is sandwiched on the hot side. Both already have fans that are blower style. Fans usually work much better when pulling than pushing into a heatsink. That being said I believe I will use some larger 120mm High performance PC fans to make sure the air flows nicely. Also PC fans are made with low sound options which is a pet peave of mine when building any project.

Anyone have ideas of hot to make this chilling unit better? suggestions ? thanks
