Cooler Master's latest addition to its Seidon line of all-in-one liquid CPU coolers, the Seidon 120V, is set for launch by mid-October. Positioned above the Seidon 120XL, the cooler features a meatier CPU block, and a 27 mm-thick 119 x 154 mm radiator. The cooler is characterized by its cuboid block+pump assembly, which supports a retention module that isn't too different in design to Corsair's Hydro H80i, except that there's no magnetic lock. Four notches at the edges of the block slide into holes on the retention module, holding it in place.

The copper base is rectangular in shape, and features a micro-fin structure where heat from the CPU is dissipated to the flowing coolant. The block+pump assembly measures about 62 mm x 62 mm x 36.4 mm (WxDxH). A 120 mm PWM-controlled fan is included, which spins between 600 and 2,400 RPM, pushing up to 86.15 CFM of air, with up to 40 dBA of noise output (as low as 19 dBA). Cooler master is speaking of improvements to the design of the pump impeller, with ceramic bearings, and a flow chamber that doesn't cave in too easily. Backed by a 2-year warranty, the Seidon 120V from Cooler Master is expected to be priced at US $49.99.
