When the Radeon R9 290 and R9 290X first launched last year, they were plagued by issues of overheating and variable clock speeds. We looked at the situation several times over the course of a couple months and AMD tried to address the problem with newer drivers. These drivers did help stabilize clock speeds (and thus performance) of the reference built R9 290 and R9 290X cards but caused noise levels to increase as well.
The real solution was the release of custom cooled versions of the R9 290 and R9 290X from AMD partners like ASUS, MSI and others. The ASUS R9 290X DirectCU II model for example, ran cooler, quieter and more consistently than any of the numerous reference models we had our hands on.
But what about all those buyers that are still purchasing, or have already purchased, reference style R9 290 and 290X cards? Replacing the cooler on the card is the best choice and thanks to our friends at NZXT we have a unique solution that combines standard self contained water coolers meant for CPUs with a custom built GPU bracket.
Our quick test will utilize one of the reference R9 290 cards AMD sent along at launch and two specific NZXT products. The Kraken X40 is a standard CPU self contained water cooler that sells for $100 on Amazon.com. For our purposes though we are going to team it up with the Kraken G10, a $30 GPU-specific bracket that allows you to use the X40 (and other water coolers) on the Radeon R9 290.
Inside the box of the G10 you'll find an 80mm fan, a back plate, the bracket to attach the cooler to the GPU and all necessary installation hardware. The G10 will support a wide range of GPUs, though they are targeted towards the reference designs of each:
NVIDIA : GTX 780 Ti, 780, 770, 760, Titan, 680, 670, 660Ti, 660, 580, 570, 560Ti, 560, 560SE
AMD : R9 290X, 290, 280X*, 280*, 270X, 270 HD7970*, 7950*, 7870, 7850, 6970, 6950, 6870, 6850, 6790, 6770, 5870, 5850, 5830
That is pretty impressive but NZXT will caution you that custom designed boards may interfere.
The installation process begins by removing the original cooler which in this case just means a lot of small screws. Be careful when removing the screws on the actual heatsink retention bracket and alternate between screws to take it off evenly.
