These slim fans can be used in low-profile CPU coolers/heatsinks, low-profile cases, and small form factor (SFF) cases, where there is no or very little room for fitting a regular-sized 120mm fan. Slim 120mm fans can also be used on radiators (120mm / 240mm / 360mm radiators) and normal PC cases to free up some space for other components in a congested environment. You may also use them on passively cooled GPU heatsinks if you want better cooling on passively cooled graphics cards. In PC Cases they can be used as front fans, rear fans, or top-mounted fans. These slim 120mm fans might offer a bit less airflow compared to the standard 120mm fans because of their thinner fan blades and compact motor.
