Cooling System Overview

September 23, 2008

Personal computers must be constantly cooled to ensure the system runs at peak efficiency. Without appropriate cooling in place, the computer’s life expectancy is shortened and in extreme cases the computer will halt due to overheating of the components. In this video, you’ll learn how computers are cooled through heat sinks, on-board fans, computer case fans, and liquid cooling systems.

    I have a question.

    You said that the front vents are ment to bring in air. A lot of high-end cases (such as the one I have now) have a place for a fan at the front. Does this mean we place the fan so that it blows air inside?

    Thanks,
    Aneeq

      Usually I have two fans at the rear of the case as exhaust fans and then the one or two (in some cases) at the front as intake fans. I find the best circulation seems to be intake at the front so that the air passes over all the components in the case then exhaust out through the power supply and the exhaust fans at the back. In most cases you do not need the intake fans as the holes and openings in the case itself are enough to allow fresh air to be drawn into the case, but an intake fan can never hurt. Grant

    I have two PCs, one is a server and it makes alot of noise from fan inside. Now I can look at the fans and determine what type of fan it is and possibly replace it with a quieter type. Thanks.
