These coolers are based on the 7th generation of AIO CLCs by Asetek, which feature variable pump speeds starting at 840 RPM, and improved ROG Strix fans included with the coolers. The round pump-block of the ROG Strix LC II is Asetek-standard, and compatible with AMD's sTRX4/sWRX8 CLC brackets.

The ROG Strix LC II 360 comes with the largest radiator of the series—360 mm x 120 mm, its ARGB model includes illuminated fans.The 120 mm fans included with the 240/360 models turn at 800 to 2,500 RPM, with a stunning 5.00 mm H₂O static pressure, 80.95 CFM max airflow, and 37.6 dBA max noise output. The 140 mm spinners included with the 280 model come with Axial-Tech webbing, do 700 to 2,100 RPM, push 102.3 CFM max airflow with 3.1 mm H₂O static pressure, and 35.7 dBA maximum noise output.
