Phanteks has unveiled its Glacier G40 water blocks designed for the latest GeForce RTX 40 series graphics cards. Phanteks has made a design change from the previous model by moving the tube fittings, which use Viton O-rings, to allow for better routing which should aid those with smaller chassis and the block now includes a GPU bracket. The block features a clear acrylic cover (jetplate) over the GPU, a full-cover copper coldplate for other items on the PCB such as VRAM chips and power components, and an anodized aluminum backplate for additional cooling. D-RGB is also supported allowing the block lighting to synchronize with other lighting elements in a build. The pricing and release date has not yet been announced.

Press Release

With the new generation of GeForce RTX 4000 cards announcement, Phanteks today unveils the upcoming Glacier G40 GPU water blocks for RTX 4000 Series cards. The Glacier G40 GPU blocks bring the ultimate cooling performance with some unique water block features to build amazing water-cooled systems.


Phanteks’ Glacier G40 GPU blocks provide a high-performance water-cooling solution custom-designed for the latest GeForce RTX 4000 series cards. A clear acrylic jetplate directly over the GPU die ensures optimal heat transfer. The backplate is included with all models to provide a clean integrated look while also providing additional cooling to the back of the PCB. In addition, the full cover copper coldplate directly cools all memory and power delivery components on the PCB with high quality thermal pads.


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


Like all Phanteks’ Glacier products, the Glacier G40 GPU blocks are made in Taiwan using only 100% copper, cast acrylic, anodized aluminum covers and extremely durably 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 GPU blocks will support the RTX 4000 Series with more to follow in the future. Please check the Phanteks website and social media for more details on support and availability.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
