NCT218 is a temperature sensor chip marked T2* by silkscreen. The common silkscreen is T2F, T2Y, T2H, etc. It is mainly used on hash boards such as S17+ and S17E.

The NCT218 is a dual−channel digital thermometer and under temperature / over temperature alarm, intended for use in thermal management systems requiring low power and size.  The NCT218 can measure the temperature of a remote thermal diode accurate to ±1°C and the ambient temperature accurate to ±1.75°C. The device operates over a wide temperature range of −40°C to +125°C.
