EK's ready to liquid cool AMD's latest GPU flagship

AMD has just revealed their Radeon RX 7900 XTX, and EK is already ready to liquid cool it. EK's new water block design is purpose built to cool the chiplet design that AMD's Radeon RX 7900 XTX is based on, cooling AMD's Graphics Compute Die and Memory and Cache dies using a custom cooling engine. EK's new block design was also created to cool the VRMs, VRAM chips, and voltage controllers on AMD's reference Radeon RX 7900 XTX model. 

EK's new Radeon RX 7900 XTX water block ships with a clear Plexi top or a black acetal top, with both models coming with a black full-coverage GPU backplate. The Plexi version will come with EK's D-RGB lighting along its longest edge, giving users access to bright clear lighting with concealed LEDs. 

At this time, it is unknown how overclockable AMD's Radeon RX 7900 series graphics cards will be, but PC builders are expected to achieve top day-to-day GPU overclocks when using a custom liquid cooling setup. 

Below is what EK has to say about their new RX 7900 XTX GPU water block.

Press Release - AMD RADEON RX 7900 XTX GPUS ALREADY GET THEIR EK WATER BLOCKS

The long-awaited 3rd of November is here with the latest AMD Radeon RX 7000-series GPUs launch. More good news is that EK, the premium water-cooling gear manufacturer, is ready with EK-Quantum Vector² water blocks for the reference models of the new AMD Radeon RX 7900 XTX GPUs. The new Radeon graphics cards come with a special memory cache dies (MCD) next to the main chip - Graphics Compute Die (GCD). The cooling engine has been modified to cool the MCDs as well, aside from the usual GPU components that are also being cooled, like the VRM, VRAM, Voltage Controllers, and the chip die.

The new Radeon RX 7900 XTX GPUs have GCD that is manufactured in a cutting edge 5 nm process, allowing 54% improvement of performance per watt. While the GPU is efficient, it does still use more power than the previous generation. At 355 W total board power that is packed in a smaller package than ever, with 300 mm² GCD that contains 165% more transistors per mm² than the previous generation. Overall these GPUs feature 58 billion transistors for 61 TFLOPs of performance.

EK-Quantum Vector² RX 7900 XTX D-RGB

The EK-Quantum Vector² RX 7900 XTX D-RGB is the first Vector² water block for Radeon GPUs, featuring full EK-Matrix7 compatibility. They are engineered exclusively for the AMD Radeon RX 7900 XTX GPUs. This liquid cooling solution encompasses a Vector² series water block and a black-anodized aluminum backplate in the same package. Like the rest of the Vector² series water blocks, the look is dominated by minimalist straight lines and the backplate coming around the side of the GPU to cover the PCB in its entirety.

What differs from all other Vector² water blocks is that the cooling engine for this water block has been rotated 90°, so the fins are perpendicular to the die. For optimal delta, the coolant flows over the graphics core die first, and the memory cache die after. Consequently, all MCDs get the same temperature coolant thanks to the high-precision 3D-machined acrylic jet insert. Fin density has been increased from 0,6/0,4 to 0,4/0,26mm to account for the increased power dissipation requirement from the new Graphics Core Die and six MCDs.

Available finishes:

- Nickel + Plexi
- Nickel + Acetal

The Vector² cooling engine combines the jet plate with a 3D-machined Plexi insert to improve flow distribution and thermal performance. This cooling engine is based on an Open Split-Flow cooling engine design, which proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, meaning it can be used with weaker water pumps or pumps running on low-speed settings and still achieve top performance.

All Vector² GPU water blocks use an 11-mm thick copper coldplate with a directly attached acetal terminal and a robust single O-ring top design for fewer possible points of failure. This simple construction provides confidence during customization and maintenance. Two distinctive and unique D-RGB lighting options are now available to complement the material choice of the product: Nickel + Plexi and Nickel + Acetal. Both versions include a black-anodized aluminum backplate and a base that is CNC-machined out of nickel-plated electrolytic copper. The backplate also provides additional passive cooling to the back side of the PCB, further improving the cooling capacity of the water block.

On the Plexi version, the D-RGB LED lighting is deployed on the longest edge of the water block for improved uniformity and brightness. The PCB and diodes are concealed inside a clean aluminium extrusion.

On the Acetal version, a unique design with a dense D-RGB LED strip illuminates the parting line of the stand-out element on both sides of the block. This subtle effect allows vivid displays of color while the block remains entirely black.

Tactile magnetic covers conceal the terminal screws, allowing the branding to rotate when the GPU is inverted inside the case.

The GPU water blocks have a specific cutout that enables you to utilize the included multi-use tool to decouple the PCIe safety on the motherboard and easily unplug the GPU. Using the same tool, you can also detach the power cable and tighten the standoffs more easily.

EK-Quantum Vector² Backplate
Each Vector² water block comes with a CNC-machined black-anodized backplate. The backplates also include captive nickel-plated mounting screws to replace the original black ones. The backplate has a new L-shaped profile that comes in contact with the water block's base and encloses the entire GPU, thus increasing the cooling surface and providing even better performance. This connection with the water block, which is far more efficient at heat transfer, enables a further increase in performance.

Captive backplate screws simplify installation, ensuring the correct length is always used where necessary to avoid any user error or second-guessing.

EK-Matrix7 Standard

EK-Matrix7 standardizes the dimensions of the products, including the port position and spacing, making liquid cooling loop assembly easier and more intuitive. All Vector² products feature full EK-Matrix7 compliance in every axis, ensuring easy integration and alignment with all other EK-Matrix7 products. This brings perfect alignment of ports in both horizontal and vertical positions, meaning less time is spent planning the loop and bending tubes, with the end result being an epic build.

Pricing (MSRP):

EK-Quantum Vector² RX 7900 XTX D-RGB - Nickel + Plexi 239.90€
EK-Quantum Vector² RX 7900 XTX D-RGB - Nickel + Acetal 239.90€
Ships from Early-December, 2022
