Cooling - CompTIA A+ 220-1201 - 3.5

All of the technology inside of our computers creates heat. One of the best ways to cool off the inside is to pull cool air through the system using fans. It's very common to pull cool air into one side of a case, have that cool air pass over the much warmer components inside, which of course heats up the

air, and the hot air is expelled out the other side of the case. The layout of devices on the motherboard and the other components inside the case all contribute to how well the air can flow through this particular case. You want to be sure to make sure all of your wires and other components are out of

the way and that you have a good air flow to pass from one side of the case to the other. There are many different types of cases, many different types of cooling systems and all of these work together to provide you with an optimal form of cooling. If you look at the different adapter

cards inside of your computer, you may find that the cards themselves have their own fans. This takes the cool air inside of your computer and directs it to a single point on this particular adapter card. It's very likely that the components of this particular kind of adapter card get very warm and need this

additional cooling of an onboard fan. Of course, to support this onboard fan, we need enough room. So, you may find these fans are only used on larger adapter cards. Very often, you'll find these types of fans on high-end video cards or graphics cards. The fans that are installed onto the case of your computer

come in very standard sizes. And you'll often find 80 mm, 120 mm, or 200 mm sized fans. These fans are often variable speed, so they'll run at slower speeds while your computer is cool and then run faster and faster as your computer heats up. This means that as the fans go faster, the noise gets a bit
