Keep your aquarium at a stable and comfortable temperature with this auto on/off aquarium chiller fan, suitable for both freshwater and saltwater tanks. Featuring a 7-wing fan design, it delivers strong airflow for fast cooling while remaining quiet and energy efficient.

The built-in controller allows you to adjust wind speed (5 levels) and set a timer (0.5H / 1H / 2H / 4H / 12H), so the fan turns on and off automatically without daily manual operation. One controller and power adapter can control 2–3 adjustable fan heads at the same time using the included 3-pin splitter cable, keeping your setup neat and space-saving.

Made with a durable ABS shell, all-copper motor, and FDB bearings, this cooling fan offers reliable performance, smooth airflow, and low noise—perfect for year-round aquarium cooling and worry-free use.
