Before Unboxing, some might be thinking what is Liquid Cooling and how it works?

The Antec KÜHLER series high-performance CPU coolers are intended specifically to provide optimal cooling for the most complex, high-powered builds – with convenient options to suit all kinds of systems.

How Self-contained Liquid Cooling Works:

The Science of Liquid Cooling:

  • Liquid has a higher heat density than air
  • Liquid is 784 times denser than air
  • Liquid absorbs heat 23 times faster than air
  • Example: 65F room temperature vs. 65F pool temperature

This enables liquid to:

  • Absorb large amounts of heat energy in a small area
  • Transport / dissipate this heat energy over long distances
  • Utilize a wide range of heat exchanger variants to transfer heat energy to air

The Arrhenius Equation:

  • Component life raises with degree temperature decrease
