EK Evolution


Early Edvard König days (1999-2003)

In 1999, Edvard König bought his first computer. Soon he had realized that air cooling is not enough to cool his highly overclocked computer. So he tried to find an appropriate substitute. He found out about water cooling and shortly after he had a great desire to make his own water block. He spent days, nights and weekends developing sketches of water blocks.

  • In early 2003, Edvard’s dream came true. He finally designed and machined his first prototypes called the EK-1, EK-2 and EK-3. Edvard’s friend David joined the team to create their first CPU die simulator. Simulator helped the duo to find the best design with the tools they had at their disposal.
  • In 2003, Edvard designed the EK-4 from the experiences learned in the past.
  • By late 2003, the EK-6, derived from EK-4, became Edvard’s first mass produced CPU water block.
