Motherboard cleaning
Why? Dust and especially particles of cigarette smoke can build up and corrode circuitry causing various problems such as computer lockups
Caution: When inside the computer take the necessary ElectroStatic Discharge (ESD) precautions and try to avoid unplugging any cables or other connections.
Procedure: Our recommendation when cleaning the motherboard from dust, dirt, or hair is to use compressed air.
When using compressed air, hold it in the up-right position to prevent
any of the chemicals from coming out of the container, which may damage
or corrode the Motherboard or other components. Also, ensure when using
compressed air that you always blow the dust or dirt away from the
motherboard, or out of the case.
Another good alternative to compressed air is to
use a portable battery powered vacuum that can effectively remove the
dust, dirt, and hair from the motherboard completely and prevent it from
getting trapped within the case. However, do not use a standard
electricity powered vacuum as it can cause lots of static electricity
that can damage the computer. When using a vacuum keep it a couple
inches away from the motherboard and all other components to prevent
damage and anything from being sucked into the vacuum (e.g. jumpers or small cables).
Tip: When cleaning the inside of the case also look at any fans or heat sinks. Dust, dirt, and hair collects around these components the most.
System fan Cleaning
Cleaning a computer system fan, whether it is a CPU fan, case fan, or power supply fan, requires some care and the right product. Below, are the steps and suggestions for cleaning the fans within your computer to help keep your computer running cool and efficiently.
Caution: While inside the computer, make sure it's off and that you're familiar with ElectroStatic Discharge (ESD) and its potential dangers.
When cleaning a PC fan, it is best to make sure the fins of the fan do
not spin. Keep the fins in place while using canned air or the
vacuum/duster. This helps prevent damage to the fan and make it easier
to remove the dust from the fan.
Clean fans with compressed air First option for cleaning computer fans, or any computer part in general, is by using canned air designed for electronics. This type of canned air is designed to be static free, helping prevent damage to computer components. Using canned air made for cleaning electronics is the safest approach, as well as the cheapest.
Tip: When using compressed
air try to position the computer in a way that helps the dust and dirt
escape the computer and not just move somewhere else in the case.
Clean with electronic vacuum
The second option is using a small electronic vacuum or electronic duster. These devices are designed to reduce the chance of static generation or discharge, helping protect electronics like canned air for electronics.
Caution: Use caution when
using a vacuum that plugs into the wall. These vacuums generate ESD,
which could damage your computer. Whenever using these types of vacuums,
remove the fan from the computer.
Damp cloth
If the computer you're working on is in around a smoker, the fan may look like the picture shown in the picture on this page. In this situation, it's usually best to moisten a cloth with water and rub the fan down. We also highly recommend removing the fan from the computer when using a damp cloth.
Once you've decided what you're going to use to clean the fans open the computer case and locate the fan you want to clean. In most situations, you're going to need to remove the fan so that both sides of the fan can be cleaned. If the CPU fan is connected on top of a passive heat sink, it must be removed to access the dust on both sides of the fan and dust in the passive heat sink.
Once the fan has been disconnected from the computer holding the fins
of the fan in place with your fingers or placing your finger in-between
the blades either blow the dust away using the compressed air or suck up
any dust using an electronic vacuum.
