why do you need to draw air in? I don't think you are using what you need to use, I think you are using what you want to use. Its funny that tech companies spend millions of dollars designing their products, with things like heat dissapation in mind, and we figure that we need to add a 10 dollar fan to keep everything from going super nova.... If it makes you feel better, put a fan in. Its kinda like a night light, it keeps the pretend boogey men away. Doesn't actually help anything, but if it makes you feel better, go for it. |

I guess what I do is funny? Heat concerns are real and justified, but you have to understand what the goal is. In this case, we have a relatively small heat source in a large air space. If the air starts out cool, even if there is poor ventilation, we will still be able to use the PC for quite a while before there is an issue. If there is designed ventilation, all it has to do is remove more heat than the system is adding. There are local effects that could cause issues, but in general that's the goal. Modern consoles and laptops have a lot of heat generated with very small air space. As a result, they MUST control their thermal environment. The easiest/cheapest thing to do is to put a heat sink on the chips that generate heat. In the case of these small environments, there isn't enough thermal mass in the air to keep things cool for very long. Thus, they add fans (either intake, outlet, or both) to get fresh ambient air into the case. In the end, essentially all thermal problems can be solved by providing a large enough deltaT! |

My 2 cents is just have a few air holes and you are more than good. If overheating was such an inevitable issue in a large closed space, you would see a standard of fans mounted on the backs of every armoire style TV cabinet. All their recommendations simply just say to leave a few inches clearance around your different devices and give them room around their ventilation to individually cool themselves. I'm sure if you had 5 hot devices all crammed together in a closed shelf of an armoire, it might have heat issues, but those cases are not common to the normal user. Something like 1 computer in the bottom of a 5 foot tall wooden box with gaping holes is not a major concern. Otherwise I would feel a temperature rise when i open the back of of my cabinet. somehow its the same temp as outside my cabinet. |

AHA! Why are companies spending so much money hiring people like Bkenobi when any jackass just needs to add fans! Stop screwing us on OEM corner cutting Bkenobi! We want to feel the breeze coming off our electronics. I expect my entertainment center to cause a damn mini hurricane when I am running all of that stuff! :angry: |

I'd be careful about that next electronic device you purchase. :P |
