Although previous works addressed the problem of temperature
monitoring in many individual components ( [8],
[9] and [10]), complex electronic systems monitoring is still
a challenging issue. Complex electronic systems encompass
a collection of integrated electronic components designed to
perform highly complex tasks.
Graphics cards or video cards are examples of complex
electronic systems that are used by many people in a wide
variety of applications such as [11], [12] and [13].
This work proposes a methodology to monitor temperature
and detect over temperature events in graphics cards. The
method was designed to work for graphics cards of different
manufacturers and different models.
It is interesting to notice that for graphics cards, detecting
over temperature events, could help not only to avoid the
electronic component degradation, but could be useful to detect
components that are not working properly. An example of this
fact may be observed in a situation of a clogged fan. In such
situation, an over temperature event would be an indicative that
some component (the fan) is not working as it should be. In
