why settle for less, its not like its much more money for a dual rad. and plus. a dual rad is e-penis +2. i was considering getting a dual but then i found a tripples only 10 bucks more for a hell of a lot more performance. so i went for it.
mainly the single rad will only cool your cpu, maybe decently, but not much more than a high-end air. i would rather get a dual rad.
but if you go to a lan and someone see's you have a single rad, i would think he would say "cool" but then inside think "meh, only 1 fan" but if you had 3 fans, then he would be "god i want that"
