1080P in a lot of ways is easier than 1080i, since it is just outputting the same frame structure, and not modifying the video at all. 1080i, like what is found in broadcast TV, is not the same frame structure, and as such, has to have considerable work done to it.
the short version is, a 1080i signal contains even lines on frame 1, and odd lines on frame 2. when played back on a progressive system, the graphics card has to make up the missing lines, and this can take a bit of work..
as for passive cooled cards, I saw some larger 5670's with passive coolers, or low profile 5570's, so I may not have been completely correct, but pick your poison. the fans on these machines are generally at least as quiet as the hard drives in most pc's, so..
