Our story: making liquid cooling a reality
The liquid cooling solutions that we provide today have certainly evolved from our initial product offering just over a decade ago. Hardcore Computer Inc. was formed in 2006 to design and manufacture high performance computers for the gaming market. Its first product, the Reactor, was highly rated by popular review sites such as G4TV. A second product, the Detonator, was introduced a year later to compete in the workstation market.
In 2013, the company was rebranded as LiquidCool Solutions and pivoted its business model from end-to-end design and manufacture to a partner model in which LCS technology is licensed to downstream partners. LCS transformed its product line to cater to data centers, ruggedized systems, and other commercial applications.
