Details
The Alphacool Eiszapfen G1/4 Inline Temperature Sensor - Deep Black is an inline water temperature sensor, female to female: a G1/4 threaded opening on both sides, with a standard 2-pin connection, one sensor per pack. A G1/4 male to male adapter is also included, so the sensor can be used in multiple configurations.

Where it goes
Inline, it can be utilized with a radiator, a reservoir, a graphics card, a CPU waterblock, etc. With the adapter screwed in, Alphacool says it fits all exposed G1/4 threaded openings on the radiator, expansion tank, graphics card cooler or CPU cooler. To place it just before the expansion tank instead, remove the adapter and screw a connection into the G1/4 thread on both sides.
Sealed and plated
The fitting is completely sealed and galvanized, for worry free operation without leaks and corrosion.
Reading the temperature
Alphacool uses a classic NTC 10 kOhm thermistor as the sensor, with a readable temperature range between -40 and 125 °C. The cable leads into a typical 2-pin connector. That standard 2-pin connection allows use with most temperature displays (fan controllers) and motherboards. Many mainboards now offer direct connection options for such sensors, so check the manual of your mainboard. Several external controllers offer a connector for it as well.
The cable is 50cm long, which will allow the use of the sensor in even a full tower case for maximum compatibility. The same sensor also comes in a chrome version.
Compatible devices
This 10kOhm temperature sensor is compatible with the following devices:
- Aquastream XT Ultra
- Aquaduct versions with external sensor input (360 XT, 720 XT)
- Alphacool Heatmaster
- Innovatek Fan-O-Matic
- Lian Li Multipanel
- Scythe Kaze
- T-balancer
- Sensor inputs of many motherboards and fan controllers
What the loop needs
Used inline, each female thread takes one fitting with a G1/4 male thread, so two in all. With the adapter in place, that side screws straight into a port.
Notes
- Use only clear, transparent water cooling fluids. Alphacool warns that the particles and additives in pastel liquids can clog and permanently damage radiators, pumps, coolers and hoses, which can void the manufacturer's warranty.
