The Kühler H₂O K-series, our newest generation of all-in-one closed loop liquid CPU coolers, is uniquely engineered to protect your CPU’s performance, increase the life of your CPU and ensure that you can count on its performance for years to come.

Water pump
The uniquely engineered pump is integrated with the radiator, preventing unwanted vibrations from damaging the CPU.

Low profile CPU block
Only 50 mm thick
Removing the pump from the CPU block sheds excess weight, reducing the likelihood of the motherboard bending and warping over time.
