Description
Product Overview
The Chihiros Cooling Fan (Bluetooth Edition) combines an ultra-quiet, energy-efficient brushless DC motor with an integrated temperature probe to lower aquarium water temperatures by 2–4°C (3.6–7.2°F). Managed exclusively via the MyChihiros mobile app, this smart 3-speed cooling fan clamps securely onto glass rims up to 19mm thick, automatically activating based on real-time water conditions to keep your fish, dwarf shrimp, and aquatic plants in a safe thermal range.
Key Features & Benefits
Smart App & AUTO Temperature Mode: Connects via Bluetooth to the MyChihiros app to monitor live water temps and automatically trigger cooling cycles when thresholds are exceeded.
2–4°C Evaporative Temperature Reduction: Efficiently lowers water column temperatures through controlled air movement across the water surface.
3-Speed Brushless Motor: High-performance 3800 RPM brushless DC motor provides powerful, whisper-quiet airflow while consuming under 3W of power.
Integrated Digital Temp Probe: Built-in water probe provides continuous, accurate temperature feedback directly to your smartphone.
Heavy-Duty Rim Clamp: Fits glass thicknesses up to 19mm, accommodating a wide range of rimless and rimmed aquariums up to 23 inches in length.

Frequently Asked Questions
1. Can I control the Chihiros Cooling Fan manually without the smartphone app?
No. The Bluetooth Edition of the Chihiros Cooling Fan is designed specifically for smart control and requires the MyChihiros mobile app to adjust speed settings, monitor temperatures, and set up AUTO trigger modes.
2. How does evaporative cooling affect my tank’s water level?
Because cooling fans lower temperature via evaporation, water levels will drop faster while the fan is active. We recommend pairing this fan with an Auto Top-Off (ATO) system or topping off evaporated water regularly with purified RO water.
3. Will this fan fit on thick glass rimless aquariums?
Yes. The mounting clamp adjusts to fit glass panels up to 19mm thick, making it compatible with almost all standard and rimless glass aquariums up to 23 inches long.
