CPU Coolers for System Integrators

Asetek liquid coolers deliver high performance thermal control for CPU and GPUs for sustained system operation and deep overclocking potential.

We are all about liquid cooling

For more than 20 years, premier thermal solutions from Asetek have been cooling processors around the globe. We invented the sealed loop liquid cooler and we take quality and reliability seriously. Without it, we could not have become the recognized leader of sealed loop liquid coolers with over 6-million coolers in the market. To make this possible, our coolers undergo rigorous testing to ensure reliability.

  • Performance Testing
    Our liquid coolers are 100% performance tested before they leave the factory. All functions on the assembled liquid cooler are tested prior to shipment.
  • Helium Leak Testing
    We do 100% inspection of products for leaks in the factory. Each assembled liquid cooler is filled with helium under vacuum and checked for escaping gas prior to filling. If tiny Helium molecules cannot escape, neither can much larger water molecules.

With our Generation 6 technology, we’ve added new features, functionality and upgraded aesthetics for a premium look.
