Model Squama 2503R 140x25mm Reverse

Option 3 Packs

  • Reverse blades pull air in from the front for cleaner intake layouts
  • 140 mm fans move 91.15 CFM at 2.63 mm H₂O for strong radiator performance
  • Hydro-dynamic bearings run at 34 dB(A) for quiet operation under load
  • PWM control spans 800 to 2400 rpm for precise speed tuning
  • Dual addressable RGB loops sync with 5 V motherboard headers for per-LED effects

Three-pack 140 mm reverse-blade ARGB fans

This set contains three 140 mm case fans with reversed blades so the front face works as an intake. Each unit uses hydro dynamic bearings and a 4-pin PWM connector for speed control between 800 and 2400 rpm. Addressable RGB lighting runs on a 5 V 3-pin header and features a dual light loop for synchronised effects. The white frames include Squama particle patterning to smooth airflow.

PWM range and static-pressure ceiling

The 4-pin PWM interface limits automatic speed control to the 800–2400 rpm window; the fan will not spin slower or faster than this range under motherboard command. Maximum static pressure reaches 2.63 mm H₂O, which caps the fan’s ability to push air through dense radiator fins or restrictive filters. At full speed the noise level hits 34 dB(A), so silent builds may need to run below the top of the curve. Airflow peaks at 91.15 CFM, defining the upper bound for case turnover.

25 mm frame thickness

The 25 mm frame depth decides whether the fans fit in slim radiator mounts, tight side-panel clearances or compact chassis brackets. Buyers with thinner mounting slots cannot use this three-pack.

Questions about this item

Should I buy the single fan or the 3-pack for a 140mm setup?

The listing is a 3-pack of 140mm white fans with reversed blades, dual ARGB loops and 4-pin PWM control, so you get three matching units in one box.

What does 91.15 CFM and 2.63 mm H₂O mean for my build?

At 2400 RPM the fans move 91.15 CFM with 2.63 mm H₂O static pressure, giving strong airflow through radiators or mesh while staying at 34 dB(A).

Will the 5 V 3-pin ARGB and 4-pin PWM headers work on my motherboard?

Each fan uses a standard 5 V 3-pin addressable RGB connector for lighting and a 4-pin PWM connector for speed control from 800 to 2400 RPM.
