Probably all of us want to see a computer (yes any other technique) worked long and without a glitch. But to put it on the table or in any corner – and work. And not much he hummed. But always in the ambient air contains dust. The computer contains components which strongly enough heat and which need to be cooled forcibly. Hardest cool is (it may consume more power 100 W) and power supply. Cooling is provided by a metal heat sinks and fans. The computer contains at least two fans – on the processor heat sink and power supply. If you installed the graphics card performance, it can also have a fan.
Where does the dust come from?
Fans on the CPU and GPU blown radiators, removing them from the heat inside the case. The fan cools the power supply not only their active elements, but the “blowing” heat (of course together with air) from outside the housing.
The influx of the surrounding, cooler, air is carried out through the slit of the housing. Sometimes, on the rear wall of the housing mounted one or two additional exhaust fan. Thus, outdoor air (with dust) extends continuously through a computer system.
dust in the fan resulting dust gradually accumulates within a “secret places” – in the crevices of the radiators, fans, power supply. The more it accumulates dust, so much the worse cooled basking components. Sometimes it happens that the fan is clogged with dust so that it ceases to rotate at all.
If this happens in the supply unit, it crashes due to overheating. In severe cases, can burn the video card or processor. Therefore, you should periodically remove the dust from the system unit.
