| Do most people add fans to the cabinet back? |

I don't see a need to put intake and exhaust fans, as the latter will naturally create convection...unless you have some need for it to be blustery inside?..... With a PC, I would lean towards putting a fan(s) in. A high-end gaming rig, you betchur ass. I'm doubting game boards up through the early 90s perhaps were running enough current to get hot enough to need them, so they didn't put 'em in. |

I have my computer mounted in a PC case with the sides taken off inside my cabinet. I have left the back of my MAME cabinet open and over the past three years I have never had a heat issue. Extra cooling, however, never hurts. |

one of the reasons for putting intake and exhaust fans in is so you can direct the air where you want it. you dont NEED both, but then the air is gonna enter or exit either though cracks (which from what i've seen there are'nt many openings on a cabinet that are'nt intended.. they are pretty sealed up. or they though the passive vents. that can be a problem.. you dont want a short circuit in your air flow.. IE putting intake and exhaust fans right next to each other. putting intakes at the bottom will pull in cool air, cool air descends so it's coolest on the floor put a exhaust fan at the top, hot air rises on it's own, the fan however helps it make the journey to the top of the cab because it creates negative pressure and then exit from a higher elevation then where you're intaking at which creates positive pressure.. you would'nt want your exhaust air to renter though your intake. passive vents in this situation can actually hurt you.. the DC fans you'ed be using for this generally are'nt very powerful in compared to the amount of space they're operating in. they're made to be used in a small space such as a computer case. so it's sometimes a good idea to actually seal the passive vents if you go with fans. personally i plan to have 2 120mm intakes very near the computer. i'll mount the powersupply exhaust fan UP, this will also help push the air towards the top of the cab. then put a 120mm exhaust fan at the top of the cab above the monitor.. the idea is to pull cool air in to help cool the computer & powersupply.. (this creates positive pressure in the cabinet) then the air will be moved upward by the negative pressure created by the exhaust fan at the top, and then exit the cab. this could be done with either just exhaust or just intake fans but would'nt move as much and you still have to make sure your exhaust vent is the path of least resistance. |

Beretta brings up a good point, but there is an added (hidden) benefit to having two fans: If one of the fans die, you still have some level of forced airflow. |
