Do you mean the entire card along with attached cooler occupies 2 slots (like the reference design), or that the cooler itself needs two slots? Looking at the setsugen base I see it's very tall. I assume that is to give room for RAM and VRM heatsinks, but it does raise the entire cooler quite substantially as well.. Hrmh.So as of now the only 2-slot cooler I've found is the Scythe
Yeah that's crap! PWM is life. I just wish my noctua fans supported that as well, grr. I sure paid enough for them to include the feature, that's for sure.except it's manual fan speed control (which I detest).
If you don't like the Scythe for that reason, maybe you should take a look at Zalman's after-market cooler which needs 2 slots for itself. HOCP ran a test of it the other day (together with Thermalright's ridiculous three-slot cooler - with a fan attached), and it scored pretty good. Not as good as the Thermalright, and the fans made a bit of a racket on high mode, but it's better than the reference even on low.
