I did notice the case getting hot but thought it was normal because both of my shields are the same, still have not installed new image as i have had a family death and will be dealing with that for the next few weeks.
Keep up the good work.

It's been a few days since I've built out the source, and something positive has come from it!
I've been looking at the Shield and noticed (like many of you, I'm sure) just how bleepin' hot the case gets. I decided to tear the thing apart and see just what was going on.
Itus really did a number on things in there in an effort to "look slick" (I guess). the bare Octeon chip and "foam" bumper really underwhelmed me, especially since I'm not really sure that foam will do much more than trap heat against the chip - there certainly wasn't thermal tape or conductivity gel between the foam and the chip.
I noticed there was a 3-pin stub-out, and that I see 5.5v from it. So, I ordered a 30x30x10mm 5v 3pin fan and I'm going to try and mount it externally in a push configuration over the vent holes. I'll report back on that when I get it done.
In the mean time, I left the case open and running because, well, I'm lazy.
With the case off, and no changes to the software, I'm now seeing full throughput on the Shield. I'm pulling 92Mb/S on the WAN, and seeing 92Mb/s on the LAN! I really am convinced the pisspoor thermal design is causing the chipsets to throttle.
I'll keep playing with it, but the speed throughput issues have gone away since I took the cover off.
