NICE! That's exactly what I wanted to see - a big roundup of all of them. As expected, the VF900 does a degree or two better than the VF700, exactly as it should: it's something like 2/3 the weight but is a smarter design due to heatpipes. Meanwhile the Accelero puts on a good show.
Regarding the Thermalright V1, I've heard it's excellent but the problem is that with an 80mm fan on it (even at low speeds), it's the loudest VGA cooler of the bunch, and the bulk of us go to aftermarket cooling both to drop temps and to cut noise as much as possible.
