Fractal Design today announced the Celsius line of all-in-one, closed-loop, liquid CPU coolers. The lineup consists of two models based on radiator size, the Celsius S24 featuring a 240 mm x 120 mm radiator, and the Celsius S36, featuring a 360 mm x 120 mm radiator. The cooler features a slew of design refinements over the company's previous-generation Kelvin-series of coolers. It features a quieter pump-block, standardized G1/4" fittings between the block and the radiator, and discrete cabling for the radiator fans, with two or three 4-pin PWM fan headers on the radiator, with source cabling discretely attached on one of the coolant tubes.

The included Dynamic X2 fans take in 4-pin PWM input, spin between 500 to 2,000 RPM, pushing up to 87.6 CFM of air, with a noise output of up to 32.2 dBA. The Celsisus series comes with out of the box support for two of the latest CPU socket types, LGA2066 and AM4, besides LGA115x, LGA2011/v3, AM3(+), and FM2(+). The coolers are backed by 5-year warranties, and are priced at USD $109.99 for the Celsius S24, and $129.99 for the Celsius S39.
