Mind as well start a new thread for this video card which should be released tomorrow. Right now, few have this card but I expect that to change within the next month or so. The first thing we will need to know is how to properly install a water block because the shim is slightly higher then the GPU core. The only water block that I know of that will fit inside the shim is the Maze4/5 as it's designed to fit the x800. From what I remember the x800 also has a shim higher then the GPU core. Also, is the issue with mosfet cooling. This round the mosfet cooler is affixed on the GPU heat sink making it all 1 unit. Once you remove the GPU heat sink you also remove the mosfet heat sink. What we need to know is if you can use the mosfet heat sink from the X1900xt/xtx on the HD 2900XT once you remove the GPU heat sink.
Make sure you remove the 2 screws to the left in order to remove the HS cover or else you cannot remove the HS.
Here is a photo of the HS as you can see the mosfet HS is also incorporated.
In this photo you will see the millingl markings on the HS. It's not as bad as the X1900XTX that I showed sometime ago. However, they are there so a decent lap maybe appropriate.
Dry lapping with 2000 grit sandpaper appears more appropriate then anything else. As you can see the results I was able to remove the drill marks without removing much else.
Prior to lapping:
Idle 60C,
Load 80C
Idle after load 62C
Post lapping:
Idle: 55C
Load 77C
Idle after load 57.6C

I ran to an unusual problem after the first test run above (in the photo). AA will no longer work, it remains at none after I hit the reset button. Obviously a problem with the game itself.

The Maze4 does cool the R600 GPU without any modification to the WB.. Also note that DangerDen's website also states that the Maze5 can also cool the R600 without any modification to the WB. The pics will show the Maze4 on the HD 2900XT. Please note that I used the OEM HS to cool the ram and mosfets. I also took measurements to make sure that it will fit.
Measured the Maze4 contact area
Measured the inner diameter of the shim (space found within the shim)
GPU Print fits the Maze4 contact area (corners of the GPU leave no room)

Idle & Load Temps Using OEM HS
Do to the nature of AMDGPU it shows both idle and highest temps (load temps)
Idle Temps Using Maze4
I will update with load temps just as soon as I finish breaking in. Ambient is currently 30C
Edit:
Load Temps Using Maze4
Load temps at 30C Ambient is only 48C (from AMDGPU)
