Cooling module with 4 fans

A cooling module with 4 fans is a device that is always useful when the water temperature in the tank reaches a dangerously high level, which can be harmful to ornamental fish, crustaceans, corals, or plants. The cooling module has a nice aluminum body, and the fans are made of solid plastic. Thanks to its well-thought-out construction, the device lowers the water temperature by 4°C.
