Both Radeon R9 290 graphics cards appear bottlenecked by platform components at 1920x1080. Adding a couple of monitors helps the water-cooled card stand out, though. Even with both cards set to stock frequencies, and benchmarking in an exceedingly chilly lab, the air-cooled board appears to pull back on its peak performance.

Frame rates remain smooth through our Arma 3 test using standard quality settings.

Average frame rates look terribly close to the minimums we measured under the influence of Arma 3's Ultra quality preset, necessitating a closer look at frame-rates over time.

The lowest I'm willing to go is 20 FPS. Yet, even the stock-clocked boards maintain more than 25 FPS. The CryoVenom’s victory is a little hollow here.

Go look at the price of the acrylic/nickel block and the backplate. Assume they're stockpiling the leftover air coolers at some cost and will sell them in the far future for about the cost of stockpiling them.
AMD recently released these to distribution by manufacturing partners, so maybe they can now get them bare. But they couldn't when these were launched, and this is a launch card. Since I don't know the full details of AMD's recent move, I cannot comment further.
In the USA and Canada, MSI and XFX still allow owners of their cards to install aftermarket cooling solutions WITHOUT voiding the original manufacturer's warranty. (Both have supported doing so for many years.) Should the owner of an MSI or XFX card with an aftermarket cooler installed on it ever need service for that card, the original-equipment cooling solution must be reinstalled prior to returning it for service.
XFX offers a 2-year warranty on its regular R9-series cards, and a lifetime warranty on Black Edition cards. Meanwhile, MSI offers a 3-year warranty on all its R9-series cards. So should the owner of an MSI or XFX R9-290/290X card want to use the EK solution mentioned in the article, that owner would still be fully covered by the respective manufacturer's warranty.
Do you have links? I wish I'd known about MSI and XFX's exceptional policies, I would turn to them for more samples!
Actually AMD designs the cards, and TSMC manufactures the GPUs which the distributors, Sapphire included, buy the add their heatsinks and branding to.
