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.EK-Quantum Vector TUF RTX 3080/3090 Active BackplateThe 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.Enclosed:- EK-Quantum Vector TUF RTX 3080/3090 Active Backplate - Acetal- Necessary mounting screws, nuts, and washers- 1x Nickel plated brass plug G1/4- EK-Loop Multi Allen Key (6mm, 8mm, 9mm)- Thermal padsTechnical Specification:- Dimensions: (LxHxW) - 254,5x144x5x33,5mmCompatibility:- ASUS TUF Gaming GeForce RTX 3080 10G (TUF-RTX3080-10G-GAMING) - ASUS TUF Gaming GeForce RTX 3080 10G OC (TUF-RTX3080-O10G-GAMING) - ASUS TUF Gaming GeForce RTX 3080 Ti 12GB OC- ASUS TUF Gaming GeForce RTX 3090 24G - ASUS TUF Gaming GeForce RTX 3090 24G OC
