EK-Quantum Vector TUF RTX 3080/3090 Active Backplate - Acetal is a cutting-edge addition to the EK® Quantum Line. It is made to complement the existing EK-Quantum Vector TUF RTX 3080/3090 water blocks and actively cool the backside of all ASUS® GeForce RTX™ 3080 and 3090 TUF GPU.
For a precise compatibility match of this water block, we recommend you refer to the EK Cooling Configurator.

The EK-Quantum Vector TUF RTX 3080/3090 Active Backplate comes with a new terminal that replaces the stock terminal arriving with the Vector water block and links the water block and Vector Active Backplate into a single unit. This way, the whole enclosure requires only one inlet and one outlet, removing unnecessary additional tubing and reducing clutter. It is the ultimate aesthetic and performance solution that finds your GPU sandwiched between two water blocks, allowing maximum cooling.
The Vector Active Backplate directly cools the PCB hotspots that are found on the backside of the GPU core and the VRM (voltage regulation module). On the RX 3090, the VRAM located on the backside is cooled, while the RTX 3080 gets cooling for the PCB located around the front-mounted VRAM. Cooling liquid is channeled over all these critical areas.

These newly developed active backplates feature a fin array with 7 wide channels allowing for very low flow restriction. This in turn allows overall lower temperatures, while the active backplate gets more than sufficient surface area for heat transfer.
The base of the active backplate is CNC-machined out of nickel-plated electrolytic copper, while its top is CNC-machined out of durable black POM acetal. The rest of the backplate is made of nickel-plated aluminum and it does not come in contact with the liquid. These Vector Active Backplates also feature acrylic terminals that match the top cover. The watertight sealing is ensured by high-quality EPDM O-rings.

EK-Quantum Scalar² DirectLink Terminal - Plexi is an acrylic terminal that replaces the stock version of the black POM acetal terminal on the EK-Quantum Vector² Strix/TUF RTX 4080 and 4090 ABP Sets. It connects the water block with the active backplate. Sleek magnetic covers can be used to conceal the terminal screws. They allow rotation of the branding when the GPU water block is inverted in the case or is being used on a vertical GPU mount. The magnetic covers are not part of the package and should be re-used from the original terminal that came with the ABP set.

The DirectLink flow solution is the first multiple-block solution to implement a conventional 4-port terminal layout, allowing serial and parallel connections from adjacent or opposing sides of the block. It was made possible by adding a machined brass insert in the terminal that diagonally links the water block directly to the active backplate inside the acetal terminal. These brass inserts are not part of the package and should be taken from the original terminal that came with your Strix/TUF RTX 4080 or 4090 ABP set.
DirectLink proves invaluable when flexibility is required for the right setup, as in the case of a distribution plate or vertical GPU mount.

This terminal is CNC-machined out of glass-like cast acrylic.
