Coolin Fan – cooling fan

This clip-on fan is for aquarium keepers whose tanks warm up during summer heat. Heated water near corals, plants and some fish species is a common risk, and the Coolin Fan addresses it by moving warm air off the water surface and replacing it with cooler air.

Why it matters

• Surface airflow: The fan forces air across the water surface, which removes warm air above the tank. The supplier states this can lower water temperature by up to 5°C.
• Narrow, wide jet: The housing shape produces a narrow yet fairly wide stream of air, which the supplier describes as more effective than the cone-shaped flow of a conventional fan.
• Three speeds: A button switches between three operating intensities, so the cooling output can be matched to the tank.
• Adjustable angle: The movable joint between the clamp and the fan body lets you set the angle relative to the water surface.

What it works with

The fan mounts on the rim of an aquarium and is designed for tanks where water temperature rises during warm periods. It runs from a USB power source, so a separate USB adapter is required. The 150 cm cable allows placement at a range of positions around the tank.
