Lore & Background
EKWB was founded in 2003 by Edvard König, who sought better thermal and acoustic performance for his personal computer. By 2011, the company had become one of the three largest personal computer water-cooling companies. EKWB works with the overclocking community through forums to understand customer needs. In April 2024, Gamers Nexus reported that EKWB was undergoing a liquidity crisis, with unpaid suppliers and staff. Founder and CEO Edvard König admitted to delayed payments and a lack of communication. Gamers Nexus also reported that EKWB allowed a hostile work environment in its US subsidiary. The company's product line includes CPU water blocks such as the Supremacy and Quantum lines, GPU water blocks, RAM water blocks, case fans, and radiators in the Quantum Surface series. EKWB collaborates with hardware brands like Asus, MSI, and Gigabyte to produce custom monoblocks for high-end motherboards and GPUs, which cool the CPU, VRMs, M.2 slot, and chipset. Blocks are offered in copper, nickel-plated, or gold-plated bases with tops made from nickel-plated brass, acetal, or plexi.
