How does the inside of my computer stay cool?

Welcome back everybody :) Today we will talk about how the computer keeps itself cool. This piggy backs off of my earlier posts of what is inside my computer. With all of these components working together the PC has to stay cool thus it needs to operate within a safe temperature. When we talk about the temperature of the PC generally we refer to the CPU temp. Remember the CPU is the brains of the computer, so it does the majority of the work of the PC. Safe operating temperature ranges between 40c - 55c. This would be considered a safe operating range. The CPU in modern computers keeps it's cool with a heatsink, fan, or both. The CPU would sit first on the motherboard and the heatsink and/or fan would sit on top. When the CPU is working it generates heat which is then dissipated through the heat sink and if a fan is present is blown away from the CPU. The pictures to my right shows a heat sink which is the metal portion with the fins and a fan sitting on top.
Further cooling is actually done by the case fan and power supply which we will talk about in future postings.
