Водный блок EK Water Blocks

Описание товара на английском языке:



This is the 2nd generation Vector GPU water block from the EK® Quantum Line, designed for EVGA® XC3 RTX 3080 and 3090 graphics cards based on the latest NVIDIA® Ampere™ architecture. The compatibility list is not final and other EVGA 3080 and 3090 graphics cards may get confirmed as compatible in the following days. For a precise compatibility match of this water block, we recommend you refer to the EK Cooling Configurator.

An EK water block for Nvidia GeForce RTX 3080 and 3090
EK-Quantum Vector XC3 3080/3090 D-RGB water block is compatible with EVGA XC3 RTX 3080 and 3090 graphics cards.


The Vector water block directly cools the GPU, VRAM, and the VRM (voltage regulation module) as a cooling liquid is channeled right over these critical areas. The water block is in contact with the power stages of the VRM.

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 EK-Quantum Vector Series water blocks use an Open Split-Flow cooling engine design, which proved to be a superior solution for GPU water blocks. It is characterized by low hydraulic flow restriction, meaning it can be used with weaker water pumps or pumps running on low-speed settings, and still achieve top performance. The jet plate and fin structure geometry have been optimized to provide even flow distribution with minimal losses and optimal performance when used in any given coolant flow orientation.


Fin array is populated by 27 microfins with 0.5mm wide microchannels that provide optimal cooling performance, without unnecessary flow restrictions or clogging hazards.

The base of the block is CNC-machined out of nickel-plated electrolytic copper, while its top is CNC-machined out of durable black POM acetal. These 2nd generation Vector GPU water blocks also feature acetal terminals that match the top cover. The watertight sealing is ensured by high-quality EPDM O-rings, while brass standoffs are already pre-installed and allow for a safe and easy installation procedure.

D-RGB lighting on EK-Quantum Vector XC3 RTX 3080/3090 D-RGB water block
The aesthetic end-piece is housing the addressable D-RGB LED strip. This water block boasts a total of 12 individually addressable RGB LEDs, and it is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin D-RGB LED connector is to be aligned with the +5V marking on the D-RGB (addressable) header.
