Is there any aftermarket GPU cooler that can fit the HD6870 and can fit on the Silverstone SG06 case? Most of what i've seen online look like they are 3 slot coolers. I was looking at Gelid ICY VISION cooler but it also looks like a 3 slot cooler (more like 2.5). Would it be possible to get away with it or is there a 2 slot aftermarket cooler out there that I don't know of?
