Gradually, we’re seeing a certain weariness with RGB lighting. Some members of the community find the lighting too flashy , and even turn it off altogether. Fortunately, for lovers of discreet systems, Cooler Master offers its MasterLiquid Atmos II Stealth. No lighting, no illumination, just discretion!
MasterLiquid Atmos II Stealth: Cooler Master’s stealth AIOs!
All-in-one watercooling in 240 and 360 mm!
With these kits, Cooler Master announces AIOs whose radiator adopts 240 and 360 mm formats. The latter are a little thicker than usual at 29 mm. In practice, this means a larger heat exchange surface. The aluminum construction remains unchanged.
As for the pump, the brand supplies its kits with alternative pump covers. By default, a plastic cover is fitted, but you can choose between a cover with a metal lid or a model that includes a fan for the motherboard VRMs directly.
Ventilation is provided by two or three Mobius 120P fans. These mills operate at high speeds: 2400 rpm. At this speed, the static pressure reaches 3.61 mmH2O, while the air flow reaches 190 CFM.
On the assembly side, we find compatibility with AMD AM4 and AM5 platforms. On the Intel side, it will be compatible with LGA-1851/1700/1200/115x. Note that offset mounting is available on Arrow Lake motherboards.
Price still unknown!
Even though the series has been officially announced, the selling price is still unknown. Unfortunately, this is not yet known. On the other hand, we can expect a lower price than the rest of the Atmos II series. As a reminder, prices start at €110 for a 240 mm model with VRM fans, and go up to around €140 for versions with LCD screens.
