Computer Cooling and
Ventilation
Did you know that your computer is a breathing machine similar
to the human repertory system. The Computer inhales air through vents in the front of the unit by means of
fans to create suction. This cool air then travels throughout the computer’s innards and picks up heat given
off by internal components such as the memory CPU etc. Once this hot air is charged then it is extracted out
the back of the computer where the exhaust vents are located.
The computer breathing process is a pretty simple concept
that manufactures have been dealing with when designing their cases to house all the precious
components.
There are however inherent problems and issues that can thwart the proper working of a
computer system very fast. Here are a few things that will cause a cooling and ventilation malfunction.
1. The number one killer of proper computer breathing is dust. Common household
dust particles floating around a room tend to have a positive charge. The surfaces inside the computer are
negatively charged so the computer actually becomes a dust magnet of sorts literally drawing the dust in. The dust
then is lodged in the vents, heat sinks and fans inside the computer and within a short period of time will start
to choke the performance of the machine.

2. Cigarette smoke is a
vicious and potentially destructive element on the demise of a computer. The smoke contains deposits of tar that
like dust tends to be positively charged particles and when drawn into the computer attaches itself to the
components forming a gum barrier that generally causes unpredictable problems. Troubleshooting computer issues due
to cigarette smoke is difficult because different computers have different motherboard layouts that will respond
differently when a layer of tar is coated on the circuitry.
3. Poor Ventilation is also a major culprit to
overheating issues. Desktop real-estate is usually sparse. Major manufacturers for years have been
miniaturizing the size of the computer case enclosure. Even with the downsizing efforts, some people do not
like the site of the computer case so will lock it away in some cabinet with no ventilation, or place it in
some tight corner on the floor without any buffer space in the back to allow the hot air to escape. So the
computer will sit there and cook while trying to provide service.
So the question would be asked as to what to do to avoid
these issues. The answer is pretty obvious for number 2 and 3, where not smoking around the computer or to
quit smoking altogether (your lungs would appreciate it) would solve the smoke issue. Finding an appropriate
place for the best ventilation could be a challenge but just thinking about the importance of locating the
CPU box would be a start in the right direction. The big question is how to deal with the dust. The
answer would be to first locate the computer in the least dust prone area of the home. A location that
promotes good movement of air such as a room that has a window allowing fresh air to circulate. Air
conditioning or air purifying products are good to lower the incidence of dust. The air in a can is a good
maintenance tool to blow out dust attached to vents and openings. A slender paint brush and flue brush are
pretty effective in dislodging excessive dust buildup on various surfaces. If you are adventurous and want to
open your computer case to try and remove dust be cautious about electromagnetic discharge. The brushing
action could cause static buildup which could result in a more serious issue than dust. Just blow with air
and avoid touching any components
Here is a DUST-BUSTIN TIP

Use the dense green scouring pads available in any dollar store to attach Velcro strips (the
hook part) onto the case on either side of the louvers where the ventilating fan blows in, and press the
filter onto them. They hold tight, you can easily remove the filter for changing or washing, and the
filter hides the Velcro strips.
