Model TL FLEX 120 - 3 Pack with Controller

  • Reverse blades push 83.4 CFM through a 0.6mm gap for focused cooling
  • 66 mmH₂O static pressure handles dense radiators and restrictive filters
  • FDB bearings and copper shielding keep noise low at 2300 RPM
  • 5 V 3-pin ARGB syncs lighting with motherboard software while PWM sets speed
  • Wireless L-Connect 3 control adjusts fans and LCD features without extra cables

Three-Pack 120 mm Reverse-Blade Fans

This set contains three 120 mm case fans with reverse blades and ARGB lighting. A controller is included in the box. The fans use FDB bearings and copper shielding for stable operation up to 2300 RPM.

Builders Who Want Wireless or Motherboard Sync

The updated FLEX receivers support PWM speed control, 5 V 3-pin ARGB motherboard sync, and L-Connect 3 wireless management. Builds that rely on a single fixed control method without software flexibility will not benefit from this platform.

Fits Standard 120 mm Mounts With Tight Gap

Each fan has a 0.6 mm blade-to-frame gap and LCP blades that deliver 83.4 CFM airflow and 2.66 mmH₂O static pressure. The package frees up internal cabling by consolidating power, lighting, and LCD signals through the included receiver.

Questions about this item

Do I need a 5 V 3-pin ARGB header on my motherboard to control the lighting on these 120 mm fans?

The fans support 5 V 3-pin ARGB control for lighting via motherboard software, while fan speed can be managed through PWM or the included wireless controller.

Can the supplied controller run these reverse-blade fans together with standard-direction UNI FAN models I already own?

The Flex receiver platform handles PWM and wireless speed control for all connected fans, but mixing reverse and standard blades in one airflow path will reduce cooling efficiency.

How can I confirm the 83.4 CFM airflow and 2.66 mmH₂O static pressure are being reached after installation?

Monitor RPM in L-Connect 3 or your motherboard BIOS; at the 2300 RPM maximum the fans deliver the rated 83.4 CFM and 2.66 mmH₂O figures.
