Antec is an established company and brand-name in the computer component space, offering quality solutions for everything from cases and power supplies to thermal paste and case-mounted fan controllers. Their latest foray is into the world of liquid cooling. The KUHLER H20 1250 is their flagship liquid cooler, featuring an all-in-one dual pump design, a 240mm x 120mm x 25mm aluminum radiator, and hardware monitoring support via the integrated USB cable and the included Antec Grid software. The KUHLER H2O 1250 comes standard with support for all current Intel and AMD CPU offerings. To gage the performance of Antec's flagship cooler, we set it against several other high-performance liquid and air-based coolers. With a retail MSRP of $109.99, the KUHLER H2O 1250 cooler comes at a premium for all the premium features it has to offer.

The KUHLER H2O 1250 liquid cooler was designed for a single purpose, to keep your process as cool as possible. Antec includes two pumps with the unit, one integrated into each fan. The top pump pulls liquid through the radiator and pushes it to the CPU block through the radiator outlet, while the bottom pump pulls water from the CPU block through the radiator inlet and pushes it through the radiator towards the top pump.

The water block is composed of a plastic shell protecting the PCB and copper innards of the block. The top of the block containing an RGB LED that changes color based on block temperature, going from blue to red as the temperature increases. The base plate is a machined and polished copper plate with 12 hold down screws holding the plate to the block body. The hold down screws are arranged around the outer edge of the base paste and are counter-sunk into its surface to minimize block contact issues with the CPU. The base plate is polished to a mirror-like finish for optimal surface mating with the CPU.
