Frequently Asked Questions
Q: What type of aquarium is this cooling fan compatible with?
A: This clip-on aquarium cooling fan is compatible with most freshwater and saltwater fish tanks up to 60 cm in length. It works well for fish-only tanks, marine setups, and coral/reef aquariums, provided the tank rim or glass edge is no thicker than 1 cm where the clamp attaches.
Q: How does this fan lower the water temperature?
A: The fan works through evaporative cooling — it circulates air across the water surface, accelerating evaporation and naturally drawing heat away from the water. This can reduce water temperature by approximately 2–4°C depending on ambient conditions, humidity, and tank size.
Q: Is the fan noisy? Will it disturb my fish or the room?
A: No. The fan is engineered for silent, quiet operation, making it ideal for bedroom aquariums, living spaces, and office tanks. The low 1W motor produces minimal vibration and sound while still moving sufficient airflow for effective cooling.
Q: Does the fan rotate, and can I control the direction?
A: Yes — the fan head rotates 360°, allowing you to direct airflow precisely where you need it. This makes it easy to target specific areas of the water surface or adjust the angle as your tank setup changes.
Q: What power source does this fan use?
A: The fan operates on DC 5V (0.1A, 1W), which is compatible with standard USB power adapters (not included). The power cord is 185 cm long, giving you plenty of reach from your power source to the tank.
