Fans DeepCool FL12 SE 3IN1 Black 3 x 120mm ARGB Halo Fans - R-FL12SE-BKAPN3-G

DeepCool FL12 SE 3IN1 Black is a set of three 120 mm case fans aimed at builds where you seek a balance between cooling, low noise, and organized interior appearance. The black casing and ARGB halo lighting allow you to connect them to the 5V ARGB header on the motherboard and synchronize the look with the rest of the hardware. The speeds of 400~1900 RPM provide a wide range – from nearly silent idle to serious airflow under load. Combined with the hydraulic bearing, this is a set that is a logical choice for a modern gaming or work build.

What you get
With these three 120 mm fans, you completely fill a standard front or top configuration for a mid-tower case. With an airflow of up to 50.74 CFM and maximum static pressure of 2.04 mmAq, you can safely use them behind denser front panels or filters without “choking” the airflow. The noise level of up to ≤28.67 dB(A) is in the comfortable zone for everyday use – at lower speeds, you will “forget” about them while keeping temperatures in check. The 4-pin connector provides PWM control from the motherboard, while the separate 3-pin 5V ARGB allows flexible connection to an ARGB header or controller depending on how you prefer to arrange the cables. With a consumption of just 0.1 A / 12 V per fan, the load on the power supply and motherboard is minimal.

• A set of 3 x 120 x 120 x 25 mm fans, which is enough for a complete front intake or top exhaust solution in a standard ATX case.
• A wide range of 400~1900 RPM±10% gives you the option for a very quiet profile during light tasks and aggressive cooling during gaming or rendering.
• Maximum airflow of 50.74 CFM helps effectively expel hot air from the case or draw in cold air through filters and mesh panels.
• Static pressure up to 2.04 mmAq makes the fans suitable for operation behind dust filters or more closed front panels, where resistance is higher.
• Noise level up to ≤28.67 dB(A) allows you to maintain reasonable acoustics even at higher speeds, especially with well-tuned PWM curves.
• Hydraulic bearing for smoother operation and lower noise compared to basic sleeve bearings, suitable for systems that run many hours a day.
• 4 PIN fan connector and 3 PIN 5V ARGB for easy connection to the motherboard or controller and synchronization of Addressable RGB lighting.
• The black color and ARGB halo design make it easy to combine with almost any case and build theme – from minimalist to full RGB.
• A warranty of 36 months gives you peace of mind for long-term use in a primary or secondary system.

Who it is suitable for
This set is a good option if you are building a gaming or work machine with an emphasis on good airflow, clean appearance, and ARGB synchronization, without chasing extreme overkill. It is suitable for mid-range builds with air or AIO cooling, where you want a meaningful balance between temperature and noise. If you are pursuing an absolutely uncompromising silent fanless setup, active fans are generally not your solution.

The most sensible aspect here is the combination of three 120 mm fans, PWM control, ARGB lighting, and decent airflow and noise performance, all gathered in one set from DeepCool with a long warranty.
