Here recently one, or perhaps multiple of my fans have been running very loudly. My computer was just recently formated, new widows installed as well as defragged. It seems to do it most when I play video games - however I've played the same game since I've had my pc and it has never done this before. My g card has no fan so I know its not that. The only other fans left are my cpu and the case fans. I held my hand in the case and it feels pretty cool. However when I touch the hinksink of both my cpu and g card they are both warm. The g card heat sink is so hot I cant touch it. Does anyone have a clue what might be the problem? Maybe you can suggest a diagnostic tool that will monitor the temperatures of my cpu, etc. Thanks in advance.
