Introduction and Specifications

Fractal Design is well known in PC enthusiast circles for their excellent cases, and they also entered the self-contained liquid CPU cooler market in 2014 with the Kelvin, and today are releasing a brand new cooler lineup called Celsius. There are two models being introduced, with the 360 mm Celsius S36 and the 240 mm Celsius S24; the latter of which we have for review today.

While on the surface this might appear to be a standard 240 mm all-in-one liquid CPU cooler, there are some key features that help to differentiate the Celsius lineup in an increasingly saturated market. The hoses (themselves flexible rubber in nice-looking sleeves) are attached at both ends with metal fittings, with the radiator side the standard (and removable) G1/4 variety, and the fans connect via an unusual radiator-mounted header that receives power via a hidden fan cable in one of the sleeved hoses. Additionally, the Celsius coolers offer a dual-mode setting with the choice of automatic fan control or PWM passthrough from the motherboard - and this is controlled via a clever switch built into the trim ring around the pump.
