Just wanted to say that many motherboards actually have the option to install software to monitor fan, heat and so on. 
If they fall below the set threshhold which can be set by the user if they wish, there is the option for an alarm to 
sound. Thus it IS possible for a program written to exploit that to change the settings and cause an alarm to go off 
when, say, the temperature goes above a ridiculously low amount or the fan speed is below a ridiculously HIGH amount.
