Hope I got the right forum this time My computer is about 3 years old, It idles around 51, and can get up to 65 or higher when playing games, I generally leave the case off to help with airflow. How do you know what heatsink/fan to get? Motherboard is an Intel 865 GBF I currently have the stock heatsink/fan. I tried google but don't understand the differences between the different types of heatsinks and the thermal pastes. What make on better then the other, and are they motherboard specific or does one size fit all?
