AQUASMITH Aquarium Chiller Fan — Temperature-Controlled, Low-Noise Cooling for Axolotl, Freshwater & Seawater Tanks

Effortless Cooling for Your Aquarium

During hot months, even a small tank can feel the heat. The AQUASMITH Aquarium Chiller Fan blends evaporative cooling with precise temperature control to help keep water within a stable range without turning your setup into a laboratory project. This approach aims to support regular observation and enjoyable viewing, as the water remains calmer and more predictable for your aquatic life.

The device offers a Minimum Setting of 59°F and a Refrigeration Effect of 3–7°F, letting you tailor cooling to your tank’s needs. This configurable range supports a wide variety of setups—from axolotls and corals to densely planted freshwater tanks—helping you create a steady environment that can feel more comfortable for inhabitants and keep maintenance rhythms simple.

Smart Temperature Control, Simple to Use

Independent LED display and a high-precision temperature probe present a clear picture of set temperature and real-time water temperature. The adjustable range of 59–93°F covers many climates and tank types, delivering visible cooling when you need it without overshooting.

• Dual display for easy monitoring of set vs. real-time temperature
• Automatic start/stop helps maintain stable water temperature
• Ceramic temperature probe suits both saltwater and freshwater
• Three airflow speeds adapt to changing conditions

Quiet Power, Flexible Fit

Two brushless fans deliver high-speed airflow through a purpose-built duct, concentrating air onto the water surface while keeping noise under 40 dB. A 30° adjustable airflow angle and 360° rotation help you position the unit for a snug fit across tanks of various sizes and rim styles.

• Ultra-quiet operation suitable for living spaces
• 360° rotation and 30° angle for flexible placement
• Three modes include ultra-quiet, continuous operation, and high-performance for extreme heat

Easy Setup and Reliable Support

Out of the box, the cooler includes a power plug for quick setup and an adjustable clip that fits rim widths from 0.2in to 0.95in. The independent controller helps shield internal electronics from moisture, and the system is designed to work with both freshwater and saltwater tanks. If you have questions, our support team replies within 24 hours, helping you find a practical setup for your tank.
