High-Performance Liquid CPU Cooler

The Corsair CWCH70 is a closed-loop liquid cooler built for enthusiasts who need reliable thermal management for modern desktop processors. It fits all current AMD and Intel sockets with hardware included in the box.

Improved Cold Plate and Dual-Fan Radiator

A low-profile pump assembly and redesigned cold plate make installation straightforward while improving heat transfer from the CPU. The thicker radiator nearly doubles the cooling surface area, and two 120mm fans mount in a push-pull layout to maximise airflow through the fins.

Thermals, Noise and Power Draw

The 120mm fans operate between 1600 and 2000 RPM, delivering 50.35 to 61.2 CFM of airflow. Acoustic output ranges from 26 to 31.5 dBA across the speed range. The unit weighs 800g and uses standard 120mm fan dimensions of 120 x 120 x 25 mm.

Questions about this item

What airflow range does the 120mm fan deliver at 1600–2000 RPM?

The fan produces 50.35–61.2 CFM across its 1600–2000 RPM range, with noise between 26–31.5 dBA.

What case clearance is required for the 120mm radiator and fans?

The radiator fits a standard 120mm fan mount; each fan is 120×120×25 mm, so allow at least 25 mm depth plus radiator thickness.

How do I mount the pump block on a modern Intel or AMD socket?

Use the included universal bracket kit: fasten the back-plate, apply paste, seat the low-profile pump, then secure the thumb-screws in a cross pattern.
