Any horror stories from not properly ventilating a MAME cabinet

I get that some fans are designed to blow, and some were born to suck, but to get things flowing, a fan has to always suck from one end and blow on the other end. It's just kinda basic physics.

Point of reference. If you are talking about a fan sitting out in the open where the domain is both sides, then yes a fan both sucks and blows. However, if your analysis domain has the fan mounted on the boundary, then the fan would either suck or blow. In reality though, the difference is moot as the analysis doesn't care what you call it, it just cares what the sign on the velocity is (which direction the velocity vector points).
;D

Those guys are under different pressures than we are. The first constraint is cost which is considered almost foremost into their design decisions. IIRC, the target temp for ATX boxes 40C an increase from earlier specs of 38C. A change attributed to higher thermal tolerances of PC components but I think it's just as likely cost is a major factor in that design change.
My point is, engineers don't make design decisions, Bean Counters do. Take a look at the cheap ---smurfy--- Chinese caps that flooded the market. Do you think any honest EE would spec them in a design if cost wasn't the primary consideration? Take a look at the ---steaming pile of meadow muffin--- eye-candy fans flooding the market with their absurdly low CFM ratings, assuming they're rated at all.
Besides if any of you :censored: are worth your salt, you'll apply the appropriate technique anyways, or experiment with both and analyze the outcome.

Benkenobi. Can you please explain how not including a 3 dollar intake fan blows the profitability on my 1500 gaming rig? Damn bean counters!
