That Zotac AMP! card comes with the Zalman 3000 cooler. It's definitely one of the better coolers for that card, but actually takes up three slots, so yeah no SLI.
That's too bad. Cause I'd love to SLI my GTX 470 someday when the cards are cheaper!!
Maybe that Gelid ICY is an option.
Was thinking it to be too little temp change when compared to the Zalman 3000F.
Even with a single card, I'm using a GTX 260 for PhysX, so I couldn't do that either with the Zalman I guess.
