Heating & Cooling

Chihiros Cooling Fan

App controlBluetooth

A Highveld heatwave can push a planted tank past 30 °C by mid-afternoon — lethal territory for shrimp and misery for fish. The Chihiros Cooling Fan clamps to the rim and drives evaporative cooling across the surface, typically pulling water temperature down by 2 to 4 degrees. A water probe plus built-in room temperature and humidity sensors feed its auto mode: the fan simply switches itself on when your tank needs it and off when it doesn’t.

In detail

A silent aluminium clip-on fan that sheds 2–4 °C on hot days — probe-driven, app-scheduled, summer insurance for your tank.

Cooling that watches the thermometer for you

Set a target in the My Chihiros app and auto mode handles the rest, spinning up as the probe reads high and standing down at night. Three speeds trade airflow against sound — though with a brushless motor in an aluminium shell, even full speed stays conversation-quiet.

Built like equipment, not a toy

The IP55-rated aluminium body shrugs off splash and humidity, the 9 V supply keeps everything at safe low voltage, and the whole unit sips under 3 watts — pennies a month for a summer of protection. The adjustable clamp grips glass up to 19 mm thick.

Frequently asked questions

How much can a fan really cool a tank?

Evaporative cooling typically pulls water temperature down 2 – 4 °C — usually the difference between a stressed tank and a safe one during a South African heatwave.

Can it switch itself on only when needed?

Yes — auto mode reads the included water probe (plus room temperature and humidity sensors) and spins up only when the tank crosses your set point. Control is app-only over Bluetooth.

What tanks does it fit?

Tanks up to about 60 cm, clamping onto glass up to 19 mm thick. The brushless motor in an aluminium IP55 shell stays quiet even at full speed.
