If your 780s are at stock (no overvolting), then your power draw will never really get high enough to cause this PSU's fan to spin fast enough to be of any concern. All PSU fans that are on 'top' of the PSU are intake. So, if the fan is 'facing' the floor, then it'll be pulling in air, but it will never really be fast enough to create much cause for concern. However, I do recommend a dust filter. That way, you'll have peace of mind. Not only that, but the PSU will be using the cooler air underneath the case vs. the warmer air that's inside.
