the Vapor X coolers on my 4870s were a LOT quieter and cooled better then the Toxic heatpipe coolers did (no comparason).
Edit: there are 2 different fans pictured above. The first blade looks like the Toxic cooler fan and the second pict has a more developed (better) fan blade, I wonder what blade they will use in the final one?
one other tidbit, the Vapor X coolers/Toxic on the 4870s were steel.(not alum or copper). These coolers look like the Toxic cooler thats been modified, I hope these are better made.
Here is a shot of the poorly designed Toxic cooler from a 4870(notice the heat tubes smashed flat)

They have to flatten the heat pipes in order to have more surface area of the heatpipes exposed to the heatsource.
