EK-Classic GPU Water Block RTX 3080/3090 D-RGB is a high-performance full-cover water block for Reference design NVIDIA GeForce RTX 3080 and RTX 3090 graphics cards, that are based on NVIDIA Ampere architecture. This water block comes with a pre-installed 3-pin 5V D-RGB LED strip. For a precise compatibility match of this water block, we recommend you refer to the EK Cooling Configurator.This water block is purpose-designed with a much thicker 11.2 mm copper base to clear the tall capacitors on most reference design graphics cards. This gives the water block advantage on the market of having a clean design and a wider compatibility list, without sacrificing any coolant flow restriction. The block features additional cutouts on the base to accommodate non-standard fan-headers and additional PCB components that certain reference designs have.The EK-Classic water block directly cools the GPU, VRAM, and the VRM (voltage regulation module) as cooling liquid is channeled right over these critical areas. The water block is in contact with MOSFETs and chokes to maximize cooling and minimize the chances of coil whine, unlike some products that are currently available on the market.EK-Classic GPU Water Block RTX 3080/3090 D-RGB is compatible with most reference design (not Founders Edition) GeForce RTX 3080 and 3090 graphics cards. These newly developed water blocks feature optimized flow paths that reduce hydrodynamic instabilities and vortexing (dead spots) inside of them. Additionally, this new design allows the terminal to be screwed directly onto the copper cold plate of the GPU block, making it more rigid and reducing the chances of damaging the water block. The base of the block is CNC machined out of nickel-plated electrolytic copper while the top is CNC machined out of high-quality acrylic material. The sealing is ensured by quality rubber O-rings. Screw-in brass standoffs are pre-installed and allow for a safe, painless installation procedure.This product is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the D-RGB (A-RGB) header.EKWB recommends the purchase of an aesthetic retention backplate which improves the looks of your graphics cards. The EK-Classic GPU Water Block RTX 3080/3090 D-RGB is compatible with EK-Classic GPU Backplate RTX 3080/3090 Black.G1/4\" threaded fittings can be used on both sides of the FC terminal and for multiple GPU connectivity, please refer to our offer of GPU Terminals.Technical specifications:- D-RGB cable length: 30cm- D-RGB connector classic 3-pin (+5V, Data, Empty, Ground)Enclosed:- EK-Classic GPU Water Block RTX 3080/3090 D-RGBCompatible: - ASUS EKWB GeForce RTX 3080 10GB - ASUS EKWB GeForce RTX 3090 24GB - EMTEK GeForce RTX 3080 10GB Black Edition OC - Gainward GeForce RTX 3080 Phoenix - Gainward GeForce RTX 3080 Phoenix GS - Gainward GeForce RTX 3090 Phoenix - Gainward GeForce RTX 3090 Phoenix GS - GALAX GeForce RTX 3080 SG (1-Click OC) (38NWM3MD99NN) - GALAX GeForce RTX 3090 SG (1-Click OC) (39NSM5MD1GNA) - KFA2 GeForce RTX 3080 SG (1-Click OC) (38NWM3MD99NK) - KFA2 GeForce RTX 3080 SG 10GB (38NWM3MD99NK) - KFA2 GeForce RTX 3090 SG (1-Click OC) (39NSM5MD1GNK) - KUROUTOSHIKOU GeForce RTX 3090 24GB GALAKURO (GG-RTX3090-E24GB/TP) - Palit GeForce RTX 3080 GamingPro (NED3080019IA-132AA) - Palit GeForce RTX 3080 GamingPro OC (NED3080S19IA-132AA) - Palit GeForce RTX 3090 GamingPro (NED3090019SB-132BA) - Palit GeForce RTX 3090 GamingPro OC (NED3090S19SB-132BA) - PNY GeForce RTX 3080 10GB XLR8 Gaming EPIC-X RGB Triple Fan Edition (VCG308010TFXPPB) - PNY GeForce RTX 3090 24GB XLR8 Gaming EPIC-X RGB Triple Fan Edition (VCG309024TFXPPB) - PNY GeForce RTX 3090 OC XLR8 Gaming Epic-X RGB Triple Fan Edition, 24GB GDDR6X, HDMI, 3x DP (VCG309024TFXMPB)
