EK Evolution


Edvard König buys his first computer and soon realizes that air cooling is not enough. He starts spending his time developing sketches of water blocks.


Edvard’s dream finally comes true. He has successfully designed and machined his first water block prototypes named EK-1, EK-2, and EK-3.


EK releases the very first sandwich-type Full Cover water block with a new WWA (Wave Water Accelerator) cooling engine. This product becomes the baseline for VGA Full Cover water blocks.


EK grows fast and is the first to provide a complete set of components for custom loop liquid cooling. A renowned Cooling Configurator is then introduced, becoming the new industry standard.


EK launches hydraulically balanced jet micro-fin design for VGA Full Cover water blocks, improving the thermal performance by several degrees and setting the industry benchmark.


EK enters the enterprise and server market with the world’s first water cooling solutions for NVIDIA® Quadro® and Tesla® series graphics and compute cards.


EK moves into a brand new facility and introduces EK-Supremacy EVO – the new flagship performance CPU water block that further increases the gap between competitors.


EK launches its first AIO liquid cooling unit – the Predator, setting a higher standard for performance and expandability while providing pre-filling service of EK GPU water block add-ons.


EK releases 100 pieces of Limited Edition Supremacy EVO water block, commemorating its 10th Anniversary with profits going to charity.


Pre-built fully liquid-cooled gaming PCs named EK Fluid Gaming Systems are launched, as well as the Quantum line. EK also takes part in the IN WIN® 30th Anniversary Celebration by co-organizing a highly successful “Mod in Taiwan” live case modding event.


The EK Mod Pit takes a different approach to bring PC modding closer to the general public. EK Classic line is also released, as well as the new closed-loop solution called EK-AIO.


EK introduces a new high-end CPU water block, EK-Quantum Magnitude, that wins the prestigious iF Design Award. The same year, EK teams up with the tech industry’s biggest names, bringing products like EK-QuantumX Delta TEC, MSI® MPG Carbon EK X, and Special Edition water blocks for the latest AMD® GPUs and CPUs.
