Corsair AF120 Slim RGB Review

Looking for an RGB fan that fits where a standard 25mm-thick 120mm fan won't, the AF120 Slim RGB is Corsair's answer at just 15mm deep.

It's built for small-form-factor cases with tight clearance behind the front panel or under a shroud, and we wouldn't pick it for anything else since the thin profile costs it real airflow and static pressure.

Why Slim

At 15mm thick instead of the usual 25mm, this fan fits SFF cases like the NR200 or Meshlicious where a standard fan physically won't clear the motherboard or PSU shroud.

Comparison to Alternatives

The non-RGB Corsair AF120 Slim already in this catalog has the identical airflow-focused design without the lighting, so skip the RGB version if you don't need it and want to save on the ARGB controller cost. For SFF builds that need static pressure over airflow, none of the slim fans in this catalog compete with a full-thickness fan like the Arctic P12 PWM PST, so only go slim when case clearance actually forces it.
