## Summary description

The Alphacool 17555 temperature sensor is designed for precise temperature monitoring in computer cooling systems. Made from durable acetal material, it features a compact size of 26.5mm. This sensor is essential for maintaining optimal temperatures and ensuring system stability.

## Long description

The Alphacool Acetal temperature sensor (model 17555) is a compact, cube-shaped water temperature sensor designed for integration into PC liquid cooling loops and other water circuits. Made from lightweight acetal, the sensor measures 26.5 mm and weighs approximately 29 g. It provides direct temperature monitoring with a standard 2-pin connector and is compatible with many motherboards and external controllers that accept NTC sensors.
Advantages
The sensor uses a classic NTC 10 kΩ element with a readable range from -40 °C to 125 °C. Two G1/4" internal threads allow simple installation in systems with hoses or HardTubes by attaching suitable fittings. Its small, square acetal housing reduces weight while maintaining durability, and the unobtrusive design lacks large logos to blend with other cooling components.
Suitable for
PC liquid cooling loops (graphic card and CPU waterblocks)
Custom water-cooling circuits with G1/4" ports
Monitoring with motherboards or external fan/pump controllers that support NTC 10 kΩ sensors

How to use
Install the sensor by screwing appropriate G1/4" fittings or connectors to its two internal threads, then place it at a suitable point in the water circuit. Connect the 2-pin cable to a compatible motherboard header or an external controller that supports NTC 10 kΩ sensors. Verify the compatibility and pinout in the motherboard or controller manual before powering the system. Position the sensor where stable flow and representative fluid temperature are expected for accurate readings.
Usage recommendations
Check the manual of your motherboard or controller for supported sensor types and connector pinout. When choosing mounting points, avoid locations with air pockets or very low flow to ensure correct temperature measurement.
