DeepCool FK120 Review

The DeepCool FK120 gets searched by people who want a plain white or black non-RGB fan pack without paying for lighting they'll never plug in.

It's a no-frills, quiet fan that's an easy pick for a white-themed build that doesn't need lighting at all.

Comparison to Alternatives

Against the Arctic P12 PWM PST in our catalog, the FK120 has near-identical airflow and noise numbers but ships without the six-year warranty Arctic offers. Compared with the DeepCool CF120, the FK120 skips lighting entirely for a slightly quieter, cheaper fan aimed purely at plain case airflow.
