TMC Aquarium Cooling Fans

Keep your aquarium cool and stable with efficient, low-energy cooling fans. The TMC Aquarium Cooling Fan range provides a simple and effective way to reduce aquarium water temperature using natural evaporative cooling. Designed for both marine and freshwater aquariums, these high-performance fans increase airflow across the water surface, helping to lower temperatures safely and efficiently — ideal during warmer months or in heated indoor environments. Available in multiple fan configurations (1, 2, 3 or 5 fans), plus an optional thermostat controller, this range offers flexible cooling solutions for aquariums of all sizes. Efficient Natural Cooling These fans use evaporative cooling, one of the safest and most energy-efficient ways to regulate aquarium temperature: Increases airflow across the water surface Promotes natural evaporation Removes heat from the aquarium Maintains stable water conditions Helping protect fish, corals and plants from heat stress Safe, Low Voltage Operation 12V low-voltage system Designed for continuous use Energy-efficient cooling solution Safer alternative to high-power chillers Quiet Yet Powerful Performance High-speed fans for strong airflow Low noise operation (~40dB on multi-fan models) Designed for home and office environments Two-speed settings (high/low) for flexibility Adjustable & Easy to Install Adjustable 90° mounting brackets Direct airflow exactly where needed Fits aquarium glass up to approx. 12mm Includes interchangeable mounting nozzles Optional Thermostat Controller For automated temperature control, pair with the: TMC Aquarium Fan Thermostat Controller Integrated temperature sensor Adjustable range: 20–35°C Automatically switches fans on/off Maintains consistent aquarium temperature Available Variants Choose the right cooling setup for your aquarium: Aquarium Fan Small (1 Fan) – ideal for nano and small tanks Aquarium Fan – 2 Fans – for small to medium aquariums Aquarium Fan – 3 Fans – increased airflow for larger tanks Aquarium Fan – 5 Fans – maximum cooling for large aquariums Aquarium Fan Thermostat Controller – automated temperature control 👉 Select your preferred option using the dropdown above.

They increase airflow across the water surface, promoting evaporation which removes heat from the tank. Are they better than chillers? They are more energy-efficient and cost-effective, but chillers may be needed for extreme heat conditions. Do I need the thermostat controller? It’s optional, but highly recommended for automatic temperature control.
