Frequently asked questions
- What fan size do I need?
- 120 mm and 140 mm are the most common, the case maker states the available positions. A larger fan moves the same air at lower speed and is therefore quieter. Screw spacing is 105 mm for 120 mm fans and 125 mm for 140 mm fans.
- What do PWM and 3-pin mean?
- A PWM (4-pin) fan can be regulated smoothly by the board according to temperature, a 3-pin fan runs at fixed or voltage-controlled speed. For a quiet PC we recommend PWM. Both types plug into the board's 4-pin header.
- How many fans and where?
- The basis is one or two intake fans at the front and one exhaust at the back. Top positions are used for exhaust or a liquid cooling radiator. More intake than exhaust keeps a slight positive pressure in the case and less dust.
