Reef Octopus 4 Inch Smart Fan

The Reef Octopus 4-Inch Smart Fan is a variable-speed USB fan that automatically ramps up as ambient temperature climbs, making it a good fit for aquarium canopies, enclosed stands, and equipment cabinets that trap heat from pumps and lighting.

• Behavior: begins ramping up at 90°F, reaches full CFM at 110°F
• Power: USB powered
• Rating: rated for approximately 2,000 hours of use — not intended for continuous 24/7 operation

Because it only spins up as temperature rises, it stays silent under normal conditions and only kicks in when your cabinet or canopy actually needs the airflow — useful for keeping equipment temperatures in check without running a fan constantly.

Compatible with: any USB power source; fits standard equipment cabinet and canopy mounting.
