Corsair AF120 Slim RGB vs DeepCool FK120: Comparison
Corsair AF120 Slim RGB vs DeepCool FK120 airflow compared
Start with airflow, because it is the widest measured gap between them: Corsair AF120 Slim RGB 56.3 CFM against DeepCool FK120 68.99 CFM, 18% in favour of DeepCool FK120. Add static pressure to that, 1.9 mmH2O on the Corsair AF120 Slim RGB versus 2.19 mmH2O on the DeepCool FK120, and the pattern holds. There is a split on fan thickness as well, 15 mm on the Corsair AF120 Slim RGB versus 25 mm on the DeepCool FK120. Rgb lighting is not the same on both, Yes on the Corsair AF120 Slim RGB versus No on the DeepCool FK120.
Corsair AF120 Slim RGB vs DeepCool FK120: which one fits your build
Buy the Corsair AF120 Slim RGB for small-form-factor cases with tight fan clearance and front panels needing RGB without extra depth, though it is not built for standard mid-tower or full-tower cases and radiator or high-restriction airflow paths. The DeepCool FK120 suits white or black non-RGB builds and quiet general case airflow, though it is the wrong buy for RGB-focused builds and high static pressure radiator duty. Our rating of the Corsair AF120 Slim RGB (6/10): A niche but well-executed pick for SFF cases that physically can't fit a standard-depth fan. Our rating of the DeepCool FK120 (6/10): A solid, quiet non-RGB fan for white or black builds that don't need lighting.
What Corsair AF120 Slim RGB and DeepCool FK120 have in common
