From a Phanteks press release:

Phanteks announces the release of the new Glacier G40 ASUS GPU block, designed specifically for the ASUS STRIX/TUF RTX 4090/4080 Series cards. The Glacier G40 ASUS GPU Block brings the ultimate cooling performance with unique water block features to build stunning water-cooled systems.

Phanteks’ Glacier G40 ASUS GPU Block provides a high-performance water-cooling solution custom-designed for the latest ASUS GeForce RTX 4000 series cards. A transparent acrylic jet plate is positioned directly over the GPU die to ensure optimal heat transfer. The backplate is included with all models to provide a smooth integrated look while providing additional cooling to the back of the PCB. In addition, the full- cover copper cold plate directly cools all memory and power delivery components on the PCB with high-quality thermal pads.

The Glacier G40 ASUS GPU Block also introduces some new features, such as a new fitting location to allow for better tube routing, even in the most compact chassis. To improve stability, a GPU support bracket is added to connect the water block to the rear PCI bracket so that the GPU is mounted more securely.

Like all Phanteks’ Glacier products, the Glacier G40 ASUS GPU Block is made in Taiwan using only 100% copper, cast acrylic, anodized aluminum covers, and extremely durable Viton O-rings known from the automotive and aerospace industries. The integrated D-RGB lighting beautifully complements the water block and can synchronize with Phanteks’ D-RGB accessories and compatible motherboards.

The Glacier G40 ASUS GPU block will be available in Satin Black, Chrome and Matte White color finishes.
