Antec H2O 950 KUHLER liquid cooler

The Antec H2O 950 KUHLER is a self-contained liquid cooling system designed for CPU thermal management. It arrives prefilled and requires no maintenance, using a copper cold plate to draw heat away from the processor. Two integrated 120 mm PWM fans with 25 mm thickness adjust speed automatically based on temperature. RGB LED lighting on the pump unit changes colour to indicate CPU temperature status.

Builders wanting an all-in-one cooler

This unit suits builders who want a closed-loop cooler with integrated PWM fans and software monitoring tools. The 159 mm radiator height and 50 mm depth define the space needed inside the chassis. Buyers who need a larger radiator surface area or a different fan configuration should look at other options. The fixed 120 mm fan size limits radiator compatibility to single-fan mounts.

120 mm radiator with two 25 mm PWM fans

The defining specification is the 120 mm radiator paired with two integrated 25 mm thick PWM fans. This combination determines whether the cooler fits the available mounting points and clearance in a specific case. The pump and fan assembly measures 120 mm by 50 mm, while the radiator measures 160 mm by 120 mm by 50.80 mm. Software provides control and monitoring for the complete unit.

Questions about this item

What CPU socket interface does the KUHLER H2O 950 use and what does that limit?

The unit is a self-contained liquid cooler with a copper cold plate; the socket mounting kit determines compatibility, not a pump interface.

What are the exact radiator and fan dimensions for case clearance?

Radiator is 159 mm tall, 120 mm wide, 50 mm deep; each fan is 120 mm by 25 mm thick.

How is the KUHLER H2O 950 installed and which step is often missed?

Mount the backplate, secure the pump on the CPU, attach the radiator with two 120 mm fans, then connect the PWM fan headers and USB cable for software control.
