Why clean your computer?
Nearly 1500 litres of water and 600 litres of petroleum products are needed to make a computer. Manufacturers like Dell and Hewlett-Packard believe that regular cleaning of your computer can considerably extend its life by eliminating dust and other particles which can accumulate and damage it.
Dust accumulation in computer equipment results in overheating and, eventually, inefficiency. The fans must work harder to make the air circulate and the convection cooling is less effective. In addition, overheating increases the failure rate of your equipment. Cleaning increases the life span of computer equipment.
