RayB:
Keep in mind, the fan was added to the machines later. They originally didn't come with them, but it was discovered the games ran too hot and so Atari recommended the addition. I don't know how many would have left the factory without them.
So for home use, you might get away with less powerful fans.
I struck out what I wrote above because I was trying to find a citation, but the one I found related to the HV monitor board. Could be what I was thinking of, mistaken for the main pcb fan...

I'm 100% positive that the fan on the game board set is factory on all machine, I've seen them on US cockpit and upright and my Irish cockpit.
Also the fan is drawn in the manuals and listed in the parts list (like the fan bracket and fan guard).
Any extra (monitor related) fans are not factory, but strongly advised !
Neverending Project:
I got some more info from David Adams from RAM controls about the original specification. He may even offer affordable (good quality) replacement fans before long too. Here is what he said (quoted with his permission):
--- Quote ---Atari originally used a cheap sleeve bearing fan from several different suppliers. One of which was Rotron which, up until relatively recently, was still in business. Generally, ball bearing fans are much more quiet until they eventually fail at which time they become excessively noisy. Anyhow, the original specification was for a 66CFM, 33dBa, 1900RPM fan which ran at 115VAC/60Hz. I've found MANY fans which match these specs, the only one I'm having trouble with is the physical size and hole placement. I'm still waiting on evaluation samples to arrive from three different sources. I plan to make the fan available as soon as I choose one. If I purchase a couple thousand of them, I can get the price low enough for everyone to get a quality fan for less.

Dave kicks ass! He is such an unbelieveable asset to this hobby!

Mmm, yeah but comparable fans are available everywhere...
One more thing, while doing my "fan" research I read on Wikipedia that sleeve bearing fans "may perform poorly when mounted in any orientation other than vertical." We all know how it's mounted.......horizontal.
