## Description

Air Slimmer 120 Enhanced performance 120mm slim fan with full-range PWM. Slimmer in size but statistically significant: Air Slimmer 120 is a 15.6mm thick slim fan engineered to achieve maximum performance in space-limited systems. Air Slimmer 120 features 9 scimitar fan blade designed for increased air pressure and high airflow rate, enabling quick heat dissipation through radiators or heatsinks. With the high efficiency fan blades, complemented by a specially designed grille with beveled intake edge, Air Slimmer 120 provides rapid exhaust efficiency where it’s designed to perform best in. Equipped with superior all-copper FDB and actively-cooled motor which allows Air Slimmer 120 to exhibit a low level of friction with high durability and operational efficiency.

Review: Great Fan! Super quiet and slim to fit - Love this fan! If you need a thin / slim fan that pushes a lot of air and is quiet, look no further. I have two of these in my build as exhaust fans and I can't even tell they are running, they are that quiet. I have never been let down by silverstone products as of yet!
Review: Excellent Performance and Low Noise in a Slim 120 mm Fan - Bought this fan based on a video review that compared roughly 25 slim 120 mm fans, where this model ranked at the top. It exceeded my expectations in a small form factor case, delivering lower temperatures and noticeably lower noise levels. It pairs extremely well with the AXP-120-67 and a Ryzen 9700X that is undervolted and overclocked.
