EKWB is the consumer-facing brand of LM TEK d.o.o., a Slovenian private company (Komenda, Slovenia) that designs, manufactures, and distributes premium liquid cooling solutions for high-performance computing. The product portfolio spans custom-loop components under the EK Quantum line (CPU water blocks such as the Velocity³ for AMD AM5/Intel LGA 1700/1851 and GPU water blocks such as the Vector³ for NVIDIA RTX 50 Series), the EK Nucleus AIO cooler family for maintenance-free installation, the EK Nexe line targeting simplified custom-loop adoption, the EK Pro series for workstations and servers, and the RM-4U8G high-density liquid-cooled server for AI and HPC workloads. Underlying technologies include the proprietary Wave Water Accelerator (WWA) cooling engine introduced in 2004, a hydraulically balanced jet micro-fin design (2011), and the EK-Matrix7 compatibility standard; supporting tooling includes a Cooling Configurator covering 4,185+ video cards and 3,228+ motherboards and a Custom Loop Configurator for capacity, heat-load, and flow-rate calculations.
The company operates a hybrid go-to-market model: direct-to-consumer e-commerce through ekwb.com with worldwide shipping (EU free delivery over €300), regional pre-built gaming PC brands in the US (ekfluidgaming.com) and EU, a B2B partner program (b2b.ekwb.com) for resellers and system integrators with dedicated account management, and an enterprise channel via lmtek.com for AI/HPC server and workstation deployments. Pricing spans entry fittings at €2.98 to complete loop kits above €3,300 and quote-based EK-Pro/RM-4U8G enterprise orders. The EK brand, founded by Edvard König in 2003, was consolidated under LM TEK d.o.o. in 2024 with backing from Egzakta Group; co-development partnerships with AMD, NVIDIA, Intel, ASUS, MSI, and Seagate embed EK cooling into OEM/ODM SKUs such as the ROG Maximus Z690 Extreme Glacial and MSI MPG X570S Carbon EK X.
