The EK Liquid Cooling Lineup
For turnkey CPU cooling, the EK AIO 120mm D-RGB Liquid Cooler targets compact chassis with native AM4 socket support and integrated lighting. If you build custom Intel loops, select dedicated hardware like the EK EK-Quantum Velocity 2 1700 CPU Block, Plexi. This water block provides Intel LGA 1700 socket compatibility alongside acrylic material for direct fluid visibility.
Custom configurations also divide by pump compatibility and fluid types. The EK-Quantum Kinetic TBE 200 D5 Acetal Combo suits you if you need D5 pump compatibility, six G1/4-inch ports, and acetal housing. To fill your system, premixed fluids like EK EK-CryoFuel Acid Green Coolant 1000mL provide low electrical conductivity and verified compatibility with rubber, acrylic, and PETG.
Where the EK Hardware Range Fits
The listed EK selection suits you if you build custom loops or need compact AMD cooling. Sizes run from 21mm rotary fittings and 100mL fluid bottles up to a 200mm pump-reservoir combo and a single 120mm AIO radiator. Aesthetics cover D-RGB illumination across blocks and pumps, plus unlit acetal and nickel finishes.
Key hardware gaps exist across this lineup. You find no 240mm, 280mm, or 360mm radiator options. Socket coverage omits platforms outside AMD AM4 for AIO cooling and Intel LGA 1700 for custom water blocks. You also receive no standalone tubing or unlit CPU blocks.
Choosing the Right EK Liquid Cooling Hardware
-
Match Your CPU Socket
Liquid coolers require exact mechanical alignment with your processor socket. If you choose an all-in-one unit, confirm the mounting bracket matches your motherboard platform. For example, the EK AIO 120mm D-RGB Liquid Cooler provides dedicated support for AMD AM4 sockets. Water blocks designed for Intel LGA 1700 will not fit older AMD layouts without correct hardware. Check the socket compatibility field in the product specifications before purchase to ensure proper cold plate contact.
-
Decide Between Premix and Concentrate
Coolant comes either pre-mixed or in concentrated form. Premix fluids arrive ready to pour directly into your reservoir without measuring. Concentrate options save storage volume and allow custom dilution ratios when preparing fluid for multiple loop maintenance cycles. For instance, the EK EK-CryoFuel Clear Concentrate Coolant, 100mL provides a compact base that requires manual mixing before filling. Both formats feature low electrical conductivity and non-toxic formulas. Choose premix bottles if you prioritize instant setup, or select concentrate bottles if you prepare maintenance refills in batches.
-
Verify Loop Material Compatibility
Custom liquid cooling loops combine multiple materials, including acrylic, PETG, acetal, and rubber seals. Using incompatible fluids can degrade plastics or cause chemical breakdown inside your loop over time. Formulations like EK EK-CryoFuel Premix Coolant 1L specifically test for chemical stability across acrylic, PETG tubing, and acetal components, while integrating biological growth inhibitors. Always review the published material compatibility lists for coolants and water blocks. Selecting fluids verified for all plastics and rubber gaskets in your configuration prevents degradation and maintains clarity throughout long operating periods.
-
Plan Port Counts and Plugs
Reservoirs and distribution blocks provide multiple threaded openings for fluid intake, draining, and tube routing. You must securely cap any port left unoccupied during assembly. Threaded caps like the EK Quantum Torque G1/4 Black Plug Fitting utilize CNC-machined brass bodies paired with rubber O-rings to block fluid leaks and exclude dust. Check the total number of G1/4-inch ports across your reservoir and blocks before assembly. Compare your planned tubing paths against available openings to ensure you have enough solid plugs to seal every open chamber port.
-
Check Pump Reservoir Clearance
Integrated pump-reservoir combo units combine fluid circulation and storage into a single piece of hardware. Units like the EK-Quantum Kinetic TBE 200 D5 Acetal Combo feature a 200mm height, six G1/4-inch ports, and D5 pump support. When choosing a pump combo, measure your chassis vertical height and horizontal distance from graphics cards or radiators. Also verify how you will mount the unit. If your case lacks dedicated reservoir mounting rails, confirm whether you need a separate 120mm fan bracket to secure the assembly to an intake or exhaust fan slot.

Account for Tight Fitting Radii
Routing tubing between closely spaced components requires fittings engineered for low profile clearance. Standard straight compression fittings can cause sharp tube kinks in cramped cases. Using parts such as the EK Quantum Torque Micro Rotary 90-Degree Fitting provides a compact 21mm turn radius with perpendicular rotation, threading directly into standard G1/4-inch ports using a 6mm Allen key. Check the clearance between your water block ports, chassis side panels, and memory modules. Selecting low-profile rotary fittings prevents tubing strain and keeps fluid pathways aligned across tight bends.
Frequently asked questions
Does EK offer all-in-one liquid coolers for AM4 builds?
Yes, the EK AIO 120mm D-RGB Liquid Cooler supports the AMD AM4 socket natively. It features integrated D-RGB lighting and fits enclosures with a single 120mm fan mount. Unlike modular custom loop gear, this unit functions out of the box as a self-contained all-in-one CPU cooler without requiring separate fluid filling, reservoir mounting, or custom tubing runs.
Can you use EK-Quantum Velocity 2 water blocks as standalone AIO coolers?
No, the EK Quantum Velocity 2 D-RGB 1700 Water Block is not a standalone cooler. It requires external loop hardware such as a dedicated pump, reservoir, and radiator to operate. Designed specifically for Intel LGA 1700 processors, it adheres to EK-Matrix7 dimensions and features integrated RGB illumination to route coolant across your custom loop setup.
What materials are safe to use with EK CryoFuel coolants?
EK CryoFuel premix and concentrate coolants provide broad material compatibility across common loop components. You can run them safely through systems containing acrylic, PETG, acetal, and standard rubber. These non-toxic, low-conductivity fluids also feature biological growth inhibitors in select premixes like the 1000mL bottles, protecting your water blocks and reservoirs against internal biological buildup.
How do you mount an EK pump and reservoir combo to a 120mm fan slot?
You install the EK-Loop Uni 120mm Pump Bracket directly onto standard 120mm fan mounting positions. Built from 1.5mm painted steel, this bracket provides a slim 11.5mm profile that saves chassis clearance. It supports both horizontal and vertical orientations, allowing you to secure combo units like the EK-Quantum Kinetic TBE 200 D5 within compact or crowded PC cases.
What is the difference between EK CryoFuel premix and concentrate fluids?
EK CryoFuel premix arrives ready to pour into your loop, while concentrate requires you to mix it with liquid. The 1000mL premix options provide instant filling with low electrical conductivity right out of the bottle. Concentrates, such as the 100mL bottles, offer a compact, biodegradable fluid base that you dilute yourself before cycling it through your cooling blocks and tubing.
How many ports does the EK-Quantum Kinetic TBE 200 D5 pump reservoir combo provide?
The EK-Quantum Kinetic TBE 200 D5 Acetal Combo provides six G1/4-inch ports for flexible tubing routing. This 200mm acetal combo unit features an integrated D5 pump and addressable D-RGB illumination. Having multiple inlet and outlet ports lets you plan cleaner loop layouts, add drain valves, or cap unused openings with matching G1/4 plug fittings.
How do you seal unused G1/4 ports on EK liquid cooling components?
You seal open cooling ports using dedicated plugs like the EK Quantum Torque G1/4 fittings. These caps use solid CNC-machined brass bodies paired with integrated rubber O-rings to prevent fluid leaks and block dust intrusion. Available in black, nickel, and satin titanium finishes, they thread into any standard G1/4-inch port across radiators, reservoirs, and GPU or CPU water blocks.
