The next thing that we are going to do is clean the fan of the power supply. Now, here the power supply here the fan is underneath. So what I'm going to do I'm going tilt or lie the piece on the side cause you don't want to spray with a can like this you want to try to hold it up right as possible. Come here let me show you now here this the power supply over here, this is the fan. What it does is it sucks the air from the inside of the PC and blows it out the back side. So when you spray or when you clean the fan the power supply should spray from the inside rather then from the outside go in otherwise you could end up spraying the dust all over the again inside the PC. Don't forget to spray the back side to there is going to be dust here. Where all the plugs are. Blow on the back on the outside. Spray here to where the DVD or CD Rom are and here along where the power supply. It is going to take another can here. Now there you have it the case inside is pretty much clean.
