EK-FC R9-290X DCII is a high performance full-cover water block for ASUS design Radeon R9 290X and -390X DirectCU II series graphics card. Please check our Cooling Configurator online compatibility system for detailed compatibility list!
This water block directly cools the GPU, RAM as well as VRM (voltage regulation module) as water flows directly over these critical areas thus allowing the graphics card and it's VRM to remain stable under high overclocks. EK-FC R9-290X DCII water block also features a very high flow design therefore it can be easily used in liquid cooling systems using weaker water pumps. The cooling engine now uses refined, 0.6mm wide microchannel structure to even further improve the heat transfer.

Base is made of nickel plated electrolytic copper while the top is made of quality cast acrylic material. The sealing is performed by quality rubber washers. Screw-in brass standoffs are pre-installed and allow for safe, painless installation procedure. Block is mounted with enclosed M3x4 DIN7985 screws.
EKWB recommends the purchase of aesthetic retention backplate (EK-FC R9-290X DCII Backplate - Black) which improves the looks of your graphics cards and also provide some passive cooling to the VRM section.
G1/4" threaded fittings can be used on both sides of the FC terminal. Flow orientation doesn't matter and is thus not prescribed.
Up to four EK-FC R9-290X DCII water blocks can be used on a single ATX form factor motherboard by using EK-FC Terminal (DUAL, TRIPLE or QUAD type) system or other means of interconnectivity. Please note that EK-FC Bridge & Link system is not compatible with this water block.
Enclosed:
- EK-FC R9-290X DCII series water block
- mounting mechanism with screw-in brass standoffs
- thermal pads
- thermal grease EK-TIM Ectotherm (1g)
PLEASE NOTE:
- Due to immense variety of fittings/barbs available on market and no prescribed standards, we guarantee compatibility only for connectors bought from our web site.
- This water block aligns with EK-FC R9-280X DCII.
EK-Quantum Momentum Aorus Z490 Master D-RGB is the new Quantum Line monoblock specifically engineered for the Gigabyte® Aorus Z490 Master motherboard. Featuring the latest generation Velocity cooling engine with low restriction and high performance, this monoblock is equipped with a 3-pin D-RGB (addressable) LED strip and it offers unparalleled aesthetical customization alongside superior performance! The D-RGB LED in the monoblock is compatible with Gigabyte RGB Fusion 2.0 which offers a full lighting customization experience.
EK® Momentum series monoblocks utilize the 5th generation of the award-winning EK® CPU water block cooling engine, further tweaked for performance and optimal coolant flow! This water block directly cools Intel® 1200 socket-type CPU, as well as the power regulation (MOSFET) module. Liquid flows directly over all critical areas, providing the enthusiasts with a great solution for high and stable overclocks. Like with every EK monoblock, the EK-Quantum Momentum Aorus Z490 Master features a high flow design and it can be easily used with the system using weaker water pump or lower pump speed settings as well. The Momentum monoblock also comes with sophisticated addressable D-RGB lightning which connects to a standard 3-pin 5V D-RGB header on the motherboard.
The purest nickel-plated copper available on the market is used for the cold plate which is precisely machined to a dense micro-fin structure. The nickel-plated brass screw-in standoffs are pre-installed and allow for easy installation. Top of the monoblock features a CNC machined glass-like cast acrylic top piece.
The new cooling engine is characterized by the top-integrated jet nozzle which is combined with a thicker jet plate allowing a more precise bow control. The simplified water block structure offers a more optimized coolant flow and easier maintenance, while the jet plate ensures the best contact surface for the CPU.
Unlike other solution on the market, this is a true one-piece, sturdy and reliable liquid cooling product which requires only two connector fittings for proper operation. The enclosed thermal pad is used on voltage regulator modules to improve stability, performance, and prolongs the lifespan of the motherboard. For the CPU, please use the enclosed (electrically non-conductive) thermal grease EK-TIM Ectotherm.
The block is already equipped with 3-pin 5V Addressable D-RGB LED strip which is compatible with the Aorus Z490 Master 3-pin 5V D_LED (Addressable LED Strip) headers. This product is also compatible with D-RGB controllers that support the pinout: +5V, D, Blocked, Ground. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the D_LED (Addressable LED Strip Headers)
Technical specifications:
- D-RGB connector 3-pin 5V digital LED header (Pinout: +5V, D, Blocked, Ground)
Enclosed:
- EK-Quantum Momentum Aorus Z490 Master D-RGB Monoblock
