You should ALWAYS have intakes at the bottom.  Hot air rises, and you want to use that to your advantage.  Putting intakes at the top of a system hampers your cooling efforts greatly.

There are plenty of places that sell snap-on, washable dust covers for cooling fans.  Use them on your intakes, and make sure you wash them once every few months.

OK, now I'm really confused... I've got 4 of the 6x9 speaker grills that are standard on the Midway cocktail cabinets.  I am putting 2 grills on each end of the cab and using one to hide the speaker and the other to hide a fan.  I was also planning on cutting some holes in the bottom and putting fans down there too - is this not what I should be doing?  I just want everything to be cool inside so it's not a fire hazard or anything...  Any help would be great!  Thanks.

I try not to use PC 12V fans because all the ones I have don't flow that much.  They are just standard 3" 12V PC fans.

For most games, a single 5-6" intake fan on the bottom of the machine, and some vents at the top, is plenty.  Also, having them on the bottom panel of the game helps to make the noise far less noticable.

I have used the $20 6" 120/110V fans from Radio Shack and I've been real happy with them.  When the game is on you'd never notice the noise from the fan, and they push a lot of air.  Compared to expensive "quiet" PC fans, it seems like a much better value for the airflow.

I know a lot of people disagree, but I have never understood the quiet fan idea on an arcade machine.  It seems like a non-issue to me.  None of my games have "quiet" fans, and I (and probably no one else) has ever noticed the noise.  If I'm playing a game, I have it turned up reasonably loud (not enough to bother you or have to talk loudly... but loud enough to hear it).

Is it me, or are people missing the fact that he is talking about a cocktail, not a standup ... vents at the top aren't gonna work here folks.

I am at the stage on my cocktail project where I will be installing 100mm fans shortly and my plan is to have a single intake down low and a single outflow up high. Am planning to be flexible, but haven't seen any heat issues so far with no fans installed.

The original configuration on this machine (it's a salvage) had vents drilled in the floor and a big outflow about halfway up the back.

Cheers,

Thanks.  Is there a difference between intake fans and outtake fans or is it just the way you face the fan when you install it?
