  • Our take on the Cooler Master 240L ARGB

    The MasterLiquid 240L ARGB is a 240 mm all-in-one liquid cooler with two 120 mm addressable-RGB PWM fans and a dual-chamber pump. It fits most older and current desktop sockets, including AM4, LGA 1151 and LGA 1200, but not AM5 or LGA 1700 out of the box. It suits mid-range builds where looks and quiet PWM control matter more than top-tier cooling. Against 240 mm rivals it is a solid mid-pack performer; 280 mm and 360 mm coolers handle hotter chips better.

    Questions and answers

    Does it fit AM5 or LGA 1700?
    Not out of the box. The listed sockets stop at AM4 and LGA 1200, so newer builds need a separate mounting kit.
    Is it enough for a high-end CPU?
    For most mid-range chips yes, but a 280 mm or 360 mm cooler gives more headroom for overclocked or many-core processors.
    Do the fans need a separate RGB controller?
    They need an addressable-RGB header on the motherboard or a compatible controller. The PWM fans plug into the board for speed control.
    How loud is it?
    Fans are quiet at low and medium speeds. Under sustained load the fans become audible, and some owners report pump noise over time.
    What comes in the box?
    The 240 mm radiator, two 120 mm ARGB PWM fans, the pump block, mounting hardware for the listed sockets, and thermal paste.
