My fan seems to be running a lot more than it used to when the computer was newer. For instance, when I am playing Tiger Woods PGA 2003 the fan runs almost full time. The computer sits on a table, I dont know if that matters. How often is it typical for the fan to run? Should it be running when all I am doing is surfing the internet? Could it be the aftermarket ram? I did a search but couldn't really find any answers. The computer is the one listed below, and the fan is turing on once every ten min or so.
