I've never had any video card temp issues with either the RV01 or RV02. Since I got my first Raven (the RV01) I've run GTX 470 SLI (NV reference), GTX 580 (NV reference), MSI Radeon 6950 Twin FrozrII, Radeon 7970 (AMD reference), EVGA 560Ti-448 core Classified, and now a GTX 680 (NV reference). 
The NV and AMD reference cards are all blower designs from the back of the card, but the TwinFrozr and Classified cards are not and the heatsink fin direction on these two cards are different. The TwinFrozr fins run lengthwise, and the Classy fins run widthwise. 
The RV02 and FT03 are among the best air cooled cases around. Although, if you do get a card that is longer than a Radeon 6990 it won't fit.
