Alphacool Eisfluegel Aurora HighFlow Flow Indicator with Tachometer Signal (Transparent)

For PC enthusiasts and water cooling builders who demand real-time coolant flow visibility, the Alphacool Eisfluegel Aurora HighFlow Flow Indicator delivers both functional monitoring and striking visual feedback. Installed inline in your custom loop, its transparent acrylic body reveals a spinning impeller that rotates with the coolant flow, while the integrated Hall sensor outputs a tachometer signal to your motherboard or fan controller for precise RPM-based flow monitoring. The integrated digital RGB lighting adds a vibrant glow, synchronizable with popular motherboard RGB ecosystems.

Key specifications

• Transparent acrylic body with brass G1/4" inner thread fittings
• Integrated Hall sensor with 3-pin tachometer output (5V DC, approx. 40 cm cable)
• Digital RGB lighting via 3-pin JST connector (5V, addressable)
• HighFlow design for minimal flow restriction
• Maximum operating temperature: 60°C; maximum pressure: 1.5 bar
• Optional M3 mounting holes for secure installation

Why choose it

The Eisfluegel Aurora HighFlow combines flow indication and monitoring in one compact unit. Unlike simple visual indicators, it provides an actual tachometer signal that can be read by software or hardware monitors, allowing you to set alarms or log flow rates. The transparent body and RGB lighting make it a visual centerpiece, while the brass threads ensure leak-free connections with standard G1/4" fittings.

Ideal use cases

• Custom water cooling loops in gaming PCs and workstations
• Systems where flow monitoring is critical for pump failure detection
• Builds with RGB lighting themes requiring addressable LED integration
• Enthusiasts wanting both aesthetic appeal and functional data

Good to know

The tachometer output is compatible with any standard 3-pin fan header that supports RPM reading. The RGB connector requires a compatible 5V addressable RGB controller or motherboard header. The flow indicator is designed for use with distilled water or compatible coolants; do not use with corrosive fluids. The impeller is sensitive to debris, so ensure your loop is clean before installation.
