Arctic Liquid Freezer III Pro 240

Arctic Liquid Freezer III Pro 240

The 2025+ Pro revision of the 240mm Liquid Freezer III adds a thicker 38mm radiator and a VRM fan while keeping the 240mm footprint, earning a strong 76 at enthusiast tier with LGA1851/1700 and AM5/AM4 support. It's a meaningful step up for those wanting more thermal mass without going to 360mm. Watch top-mount clearance, as the 38mm-thick radiator needs more room than a standard 240.
