120mm fan shroud for multi GPU setups

I have been attaching a fan to the end of my tri-sli'd gpu's since I first got my 480's. The 3d printable bracket I modeled for the 680's doesn't work so well with 780's in an 800D, so I hadn't been using it. The 780's are just a tad longer, and the fan would have been right up against the sata connector cover on the 800D.

After playing Farcry 3 for a few minutes on the new setup, I was surprised to see my top two cards were hitting 79 degrees, while my bottom card never got over 60. Coming
