I am currently looking for a custom cooling solution for my overclocked Club 3D HD7950. One very interesting water cooling solution which have really caught my interest is Arctic Cooling's Accelero Hybrid II 120:

http://www.arctic.ac/eu_en/accelero-hybrid-ii-120.html

Seems very easy to install and according to reviews it comes with a great cooling potential. However, the official description lists HD 7970 / r9 280x as supported but not HD 7950 / r9 280. This seems very strange to me as I would have thought they shared PCB and GPU.

Now, my questions are:
1) Have anyone by chance experience with fitting the HD 7950 / r9 280 with this cooler and if so did it work?
2) Would anyone have knowledge about the PCB and GPU of HD 7950 and 7970 and would you be able to confirm whether or not they are in fact the same?

Any input would be appreciated. Suggestions for alternative "ready-to-install" water cooling solutions are welcome as well.

1: No, I used this: http://www.quietpc.com/gel-icy-vision-amd because it's AMD only, it has a raised square on the cold plate-essential for my type of HD7950 where the GPU die sits 1 m.m. below the surface of its surround/HSF support frame.
2: Not all are the same, quite a few makers use custom PCBs which may not be compatible with an aftermarket cooler. This review shows the reference PCB and cooler layout, note the raised square on the cooler (right hand pic, 'a closer look') and location of the VRMs, 'right' hand side, under the fan.

coozie, thank you for the input. However things turned out to be a bit more complicated than just considering if the PCB is of reference design. After som further searching on Arctic Coolings home page, I actually found carification to my question:

In other words it is also a matter of production date for the card. I took my chances and uninstalled the stock cooler for a closer look. Fortunately the GPU is actually slightly higher than the support frame surrounding it (apparently opposite to your situation). Thus, the GPU cooler block of the Arctic cooler should fit onto my card.

I further worked out, that my card looks nearly exactly like the reference PCB:

http://www.coolingconfigurator.com/step1_complist?gpu_gpus=772

With the only difference being a total of three rubber supports on the top side, which are there to support the stock cooler fin block. These should however be of no consequence to the installation of the Arctic cooler fin block on the back side of the card.

Nice, I'll pop this into my favourites and keep it for reference.
Yep, yours looks like the top one, with the GPU die above the surround and with the card having an reference type PCB any of the flat coldplate options should work, liquid or air.
One point is to be careful when tightening the screws holding the cooler down, they're usually spring loaded and designed for a flat contact, not to handle a raised GPU die-be gentle but firm, tiger. ;)
Really, it's now entirely your option, I'm happy with a Gelid+Zalman Fanmate controller but if you want to go hybrid or even full liquid I can see no reasons not to other than the possible issues with radiator position, hose routing and placement of other cards below the GPU.
So, Neo, do you take the liquid pill, or the air? ;)

Haha :-D went for liquid - all the way actually. Just ordered the hybrid ii for my GPU and also a Corsair h90 for my CPU :) will report back later for future reference in the forum, if I flooded the cabinet or not :p

Better late than never: Just a report on the outcome of my water adventure. With some twists and turns I managed to install the Arctic cooler on the Club 3D card. However it is not a perfect fit - namely due to a plastic support installed on the long edge of the graphics card. That support is making it damn hard to fix the cooler bracket properly. It is also a bit of a challenge to install the GPU cooler itself, since it is impossible to tell, when the pressure is sufficient and even.

However I am getting good readings, normally hitting 55-60 °C on the GPU in full and sustained load (OC from 930/1250 to 1100/1500 MHz). The VRM temps are a bit high though. Therefore I have installed som cooling fins for the VRM chips:

http://www.newegg.com/Product/Product.aspx?Item=N82E16835708008

Together with a side mounted 140 mm fan next to the graphics card that brings VRM temps below 60 °C.

All together I am pleased with the result, although installation was a challenge. I wouldnt recommend this product but rather suggest to look at Kraken G10 or Corsair HG10 mounting bracket. These also gives a huge freedom to pick another water cooler for the job.

Hi and sorr for bumbing this thread, but i must ask this: So that arctic pic what is for checking your GPU (hd7950/280) is those grey little things next to gpu is those VRAM spots or what are those?
