AQUASMITH Aquarium Fan - Ultra-Quiet 3-Speed Tank Cooler (3–7°F)

Efficient, Flexible Cooling for Aquariums

The AQUASMITH Aquarium Fan is designed for continuous use in homes with sensitive aquatic life. By combining evaporative cooling with a targeted air delivery system, it directs airflow onto the water surface to help manage surface temperature and create a calmer, more stable environment for inhabitants such as axolotls and reef-ready setups. While conditions vary, many hobbyists notice a cooler feel to their tank during hot days or after long light periods, contributing to a more comfortable viewing experience.

Compared with traditional chillers, this compact cooler offers a more economical and adaptable cooling option. With 58 high-density blades and a dual-turbine design, it concentrates airflow where it matters most and can reach up to 3600 RPM. The brushless motor keeps noise to a minimum, delivering a whisper-quiet operation around 35 dB at typical speeds, so it won’t disrupt evenings or nighttime viewing.

Three customizable speed levels

• Gentle mode for quiet, night-time operation
• Standard mode for everyday use
• Strong wind mode for hot days or demanding tanks

Flexible installation and precise airflow

• Adjustable mounting clamp fits 0.2-0.95 inch rims, compatible with both rimless and framed tanks
• 360° rotation and 30° tilt let you aim airflow exactly where it’s needed

Simple setup and reliable support

The fan ships with a plug for quick, out-of-the-box operation. If you have questions, the AQUASMITH support team responds within 24 hours to assist with setup or troubleshooting.

Versatile for a wide range of aquariums

Suitable for freshwater, saltwater, planted tanks, coral setups, and axolotl habitats, offering an extra cooling boost without heavy equipment or complex installation.

Maintenance and care

Keep intake and ducts clear of dust and wipe the housing with a damp cloth as part of routine care. The compact design can fit behind stands or along tank sides, keeping your aquascape visible and accessible.
