The Antec Tri-cool fans aren't that bad for power draw, and they're designed to piggy-back like that. 6 of them on a single molex connector shouldn't cause any issues at all. Even if their actual power consumption is strangely excessive for their speed (say, half an amp each), that's still only 3 amps total, which is no cause for concern at all.
