Chassis fan installation problems

The first floor is right, or all out of the wind, the wind to the outside of the chassis blowing good, the power supply is also outward, you a blowing inward, because of the wind, it will form turbulence, but also to the chassis to bring a lot of dust, dust is a computer killer, I think you know it!

If you say that the side of the chassis does not have an air intake or less very much, that you have this computer chassis design is too poor, in order to reduce the cost of the chassis side of the process of punching holes will be less, you can do so, the chassis on the PCI expansion slots on the mouth of all the metal pieces to take off the air intake, understand it, that is, the new chassis is not the time to install the graphics card position was not open, the press installation, and then remove one of the air intake, the chassis will not be able to use the air intake.

You refer to it!!! There is really no need to install
