Great job and build log. Rep+

I always get a chuckle at the comments from those who are not at all familiar with aftermarket vga coolers. They usually post comments like how massive the cooler is, or how it looks funny, or how it just dumps heat in the case.
I've probably been fitting AC coolers on vga cards longer than some of these guys have been alive, and the results speak for themselves.
I was concerned that the 680 would need one of the upcoming Accelero Xtreme III coolers, but the Accelero T.T. II looks to be quite effective.
They state on the AC site that there would be a fitting issue with 680's that have the double-deck power socket:

(click on the "Compatibility" tab and scroll down)
thus the T.T. II for the 680.
Edit: @falcon26:
I had to use different spacers on my current Acceleros as well, as I removed the IHS from the 480's, and had a few thinner spacers on hand from a previous cooler.
You could possibly file down the spacers that are too thick, if there is an issue with yours. AC is very good with customer support, so they should provide a solution for this issue soon enough.
I hope they will answer your support request soon.
