I have got a desktop computer , I have installed an AMD Athlon II processor , have an ASUS motherboard , 320GB of internal hard disk space and 2 GB of RAM installed in my computer. Since I love to play computer games and that too of higher graphics so for that purpose I have installed a GTX graphic in the pcie slot of my ASUS motherboard. But since I use my system for the pc games mostly m it gets heated very quickly for that I want to know how much my heat sinks get heated, so is there any tool which will help me in measuring the temperature of the heat sink , so that I can take preventive steps if I want to keep it cooler than before . What is the reason for so much heating in my system. If you have some steps and tips for cooling , then that would be more beneficial. I am eagerly waiting for your response.
