Frequently Asked Questions
Q: How much can this aquarium cooling fan reduce water temperature?
A: The aquarium cooling fan is designed to lower water temperature by approximately 2–4°C through surface evaporation cooling. The actual drop depends on your room temperature, tank size, and airflow speed selected.
Q: What aquarium wall thickness is compatible with this cooling fan?
A: For the USB interface version, the aquarium wall or rim lip must be 9mm or less. For the EU plug version, the wall thickness can be up to 15mm. Always measure your tank before purchasing.
Q: Is the USB power adapter included with the aquarium cooling fan?
A: No — the USB power header/adapter is not included. You will need to supply your own USB power source such as a phone charger adapter, USB hub, or PC USB port.
Q: Can I use this fan on both freshwater and saltwater fish tanks?
A: Yes. The clip-on aquarium cooling fan works with both freshwater and saltwater tanks, provided the tank rim thickness is within the specified limits and the fan is kept away from direct water contact.
Q: Does this fan work quietly enough not to disturb fish?
A: The fan is designed to operate at low noise levels suitable for a home aquarium setting. The two variable speed settings let you choose quieter operation at the lower speed when maximum cooling is not required.
