The Arctic Accelero Xtreme III, Detailed
The great thing about this aftermarket cooler is a reasonable price relative to the Radeon R9 290. At $75, you can add it and still come in well under an R9 290X, but match or exceed the pricier card's performance. Of course, it's great that the Accelero Xtreme III is compatible with AMD's new cards, and is also pretty light as well.
Compared to the Alpenfoehn Peter and Prolimatech's MK-26, this thermal solution is less expensive and bundled with fans, which cost you extra after buying those other kits. It even matches the PCB's dimensions fairly well, aside from a few minor differences that we'll address during the assembly stage. They don't pose a problem, though.

As I browsed through the cooler's contents, I noticed that we were short four memory heat sinks (the R9 290 needs 16 for its 256 MB packages, and Arctic only includes 12). Fortunately, this isn't a show-stopper. Part of AMD's approach to this card was widening the memory bus to 512 bits and running its GDDR5 at more conservative frequencies, scaling back on voltage at the same time. The memory packages don't get so hot that they pose a thermal issue. If you still feel compelled to cool them off, buying an optional kit for the GeForce GTX 260/275/280 should suffice.
The Modified Card's Specifications
The cooler's specifications are interesting enough, but we needed to know if it'd fit in our case. So, next, we measured the Radeon R9 290's weight and dimensions with the new cooler set up.

|Depth||60 mm (2.5-Slot)5 mm Back-Side (Through Back Plate)|
But at the end of the day reviewers are gonna continue to mark down cards for these silly things for whatever reason. AMD might as well just make the reference coolers at least as good as SAPPHIRE's Dual-X so that everyone shuts up...
Also, try and make your layout a standard so I don't have to keep buying after-market coolers or blocks. I can just move them from board to board.
I've proofed this construction in my Corsair Obsidian 900D and it works as described, I had to turn on my case fans but only @800-900 rpm. To test a crossfire setup I would have to destroy two cards - sorry, but this was too expensive for me. One modified card is ok, but I cant kill all my samples :D
it seems the r9-290x is pretty much identical clock for clock to the 780ti... so putting a non-reference cooler onto it is almost mandatory; because when it's not temp throttling it's pacing nvidia's $700 monster.
Also, look that, that cooler is barely spinning. You can squish more of it, that would be even more noticable in performance gains!
Are all the Vendor's cards like this? If I remember correctly Sapphire used to allow (or still does) people to take the stock cooler off to attach a waterblock without it voiding the warranty.
