Phanteks Glacier G4090 Water Block

The Phanteks Glacier G4090 is a full-cover water block built for GIGABYTE AORUS MASTER and GAMING RTX 4090 graphics cards. It uses a 10mm copper base to draw heat directly from the entire PCB. Digital-RGB lighting synchronises with Phanteks D-RGB products and compatible motherboard addressable RGB headers. The block measures 11.51 x 4.94 x 1 in and features an aluminium cover plate in matte white.

Who this suits and who it does not

This kit suits builders with a compatible GIGABYTE RTX 4090 who want a single full-cover block with integrated Digital-RGB. It will not fit reference or other partner card layouts, so buyers with a different RTX 4090 model should look elsewhere. The bundle also assumes a custom loop is already planned, so those needing an all-in-one solution will not find a pump or radiator here.

Bundled accessories and their impact

The bundle includes the nickel-plated copper block, acrylic top, aluminium cover plate and Viton rubber washers for leak prevention. Digital-RGB connectors allow lighting control through existing Phanteks or motherboard ecosystems. No coolant, fittings, tubing or mounting hardware for other components are supplied, so the loop must be completed with separate parts.

Questions about this item

Which GIGABYTE RTX 4090 models does this water block fit?

It is compatible with GIGABYTE AORUS MASTER and GAMING RTX 4090 graphics cards.

Will the 11.51 x 4.94 in block clear the motherboard PCIe slots on a standard ATX board?

The full-cover design spans the entire PCB, so the slot directly beneath the card will be occupied; plan your expansion cards accordingly.

How do I confirm the Digital-RGB lighting is synchronised after installation?

Connect the D-RGB header to a Phanteks D-RGB controller or a motherboard addressable RGB header, then verify the lighting responds in the control software.
