Temperature sensor Alphacool 17597 Brass Black Chrome 18mm 17mm

The Alphacool Eiszapfen temperature sensor flat G1/4" (MPN 17597, EAN 4250197175975) is a compact brass temperature probe with a black chrome finish designed for integration into water cooling loops. With a G1/4" external thread and a shallow screw-in depth (18 mm depth, 17 mm height), it fits into any free G1/4" port on radiators, reservoirs or fittings. The sensor uses an NTC 10 kΩ thermistor, reads temperatures from -40 to 125°C and connects via a 40 cm cable terminating in a 2-pin connector, compatible with many motherboards and external controllers.

Advantages

The sensor’s compact brass construction with black chrome plating provides durability and a discrete appearance when installed. Its standard G1/4" thread and short insertion length allow easy placement at virtually any point in a water loop without interfering with surrounding components. The NTC 10 kΩ thermistor offers a wide measurable temperature range and straightforward connectivity through a 2-pin connector for direct connection to many modern motherboards or external fan/pump controllers.

Suitable for

• Temperature monitoring in PC water cooling loops (radiators, reservoirs, distribution blocks)
• Integration with motherboards that support 2-pin temperature sensor inputs
• Use with external controllers and fan/pump regulators that accept NTC 10 kΩ sensors

How to use

Screw the sensor into any free G1/4" port in your water cooling loop until it seats; the short insertion length ensures compatibility with most Alphacool radiators, reservoirs and fittings. Route the 40 cm cable to the target header or controller and connect the 2-pin plug to a compatible motherboard sensor input or external controller. After installation, verify temperature readings in your motherboard BIOS/software or controller interface to confirm proper operation.

Recommendations

Install the sensor in a location with good water flow for representative readings, avoid placing it where air pockets form, and consult your motherboard or controller manual to confirm support for a 2-pin NTC 10 kΩ sensor before connecting.
