An aquarium temperature control module includes a conductive unit, two temperature control wafers, two heat sinks, two fans, and a water inlet unit. The conductive unit includes a housing, and one formed in the housing and connected to each other a water inlet and a water outlet, the housing has two conductive walls spaced apart along a first direction, and the temperature control wafers are respectively disposed on the conductive walls, and may be heated or cooled by a change in a current driving direction. The heat sinks are respectively disposed on one side of the temperature control wafer opposite to the conductive unit, and the fans are respectively disposed on the heat sinks, the water inlet unit includes a water inlet pipe connected to the water inlet, and a connection is made a water pump and a pumping motor for pumping water, wherein the conductive walls are disposed opposite to each other in the first direction, and are respectively disposed on the temperature control wafers, so that the energy of the temperature control wafers is not dissipated when heated or cooled. Overflow, while greatly improving the efficiency of heating or cooling.一種水族箱溫度控制模組，包含一傳導單元、二溫控晶片、二散熱片、二風扇，及一進水單元，該傳導單元包括一殼體，及形成於該殼體且相互連通的一進水口及一出水口，該殼體具有沿一第一方向間隔設置的二傳導壁，該等溫控晶片分別設置於該等傳導壁，並可受電流驅動方向的改變而發熱或致冷，該等散熱片分別設置於該等溫控晶片相反該傳導單元的一側，該等風扇分別設置於該等散熱片，該進水單元包括一連接該進水口的進水管，及一連接該進水管並用來抽取水的抽水馬達，藉由該等傳導壁是沿該第一方向相反設置，且分別供該等溫控晶片設置，使該等溫控晶片加熱或致冷時的能量不會散溢，而大幅提升加熱或冷卻時的效率。
