For a central a/c system, get a two-stage fan. Mine kicks in after 4 minutes, if the temp hasn't gone down (that is configurable, can set at 2, 4 or 15 min, I think) and doubles the cooling to the affected zone.
Also, adding a short fan or fan bank in between esp hot units can help (in addition to using mesh -- also use a filter in front of the fans and clean it regularly), as that puts the cold air where it is most needed (and exhausts the hot air out the rear of of the units). As can extra fans on hd banks, etc. This helps more than just lowering total ambient air temp. As others have said, hot spots are easy to get, with temp on units easily over 100, while ambient air is well within specs. And, since hot air rises, put any air vents (or room a/c's) at floor level, while taking out air at the ceiling (this is not a normal setup in many offices, which have entry air from the ceiling and exhaust air going out low .. ok for heat and humans, not good for a/c and computers). On the other hand, you can set up your exhaust in the winter to dump into either the central heat system or just vent to an adjacent room and save on heating the humans that run the computers.
