A temperature sensing apparatus (10) and associated method (60) wherein a temperature sensor (22) or a plurality of temperature sensors (22) is placed in or in near proximity to a liquid crystal display module (12) of a computer system (11, 11a, 11b). The temperature sensor(s) (22) are placed on, or in near proximity to the liquid crystal display module (12) at positions determined according to the requirements of a particular application. Temperature of the liquid crystal display module (12) is communicated digitally to an associated computer (14) by, for example, a bus such as an inter-integrated circuit interface bus (26). When the temperature exceeds a predetermined limit, remedial action, such as increasing fan speed, reducing speed and or power consumption of other components, or the like, is taken to reduce the temperature.
