Aquarium Cooling Fan – Triple Blade

The Aquarium Cooling Fan – Triple Blade is the most powerful clip-on fan option in the evaporative cooling range, deploying three independently angled fan heads from a single mounting bracket. Designed for open-top aquariums of 200 litres and above, the three heads together cover the full width of most large aquascapes and reef sump tubs.

Each fan head can be directed independently, allowing targeted airflow across hotspot zones identified with a surface thermometer. Combined evaporative cooling capacity reaches 3–5°C below ambient in low-humidity conditions — competitive with small compressor chillers for mild temperature rises.

Used widely in reef aquariums, large planted display tanks, and fish rooms where fans provide economical temperature management during seasonal warm periods without the capital cost of a chiller.
