One of the biggest names in PC Watercooling is EK. They rose through the ranks during the watercooling land rush when the hobby started to gain traction and hardware enthusiasts were inventing block designs, experimenting with automotive heater cores and arguing about what it took to get the best performance. Names such as Danger Den, Asetek, PolarFlo, Thermalright and Swiftech were driving the market in the US while EK was doing the same in Europe.

As with many niche markets the cost of doing business is high, especially when you are dealing with the PC world. Many experienced hardware enthusiasts will experiment with bleeding edge technologies while other more reserved pc builders will stick with what they know or what they learn about from friends.
