  • TypeCase Fan
  • ColorBlack
  • LEDAddressable RGB

Model Reversed

  • Reversed blade design pulls air through tight radiator fins
  • 5V addressable RGB with side lighting illuminates the case interior
  • PWM control spans 800 to 1800 rpm for silent or maximum airflow
  • 3 to 30 dB(A) keeps acoustics low at typical speeds
  • Rated 40000 hours MTTF at 25 °C for long-term reliability

Reversed 120 mm ARGB fan for intake layouts

The Corn Electronics FR-505B uses a reversed blade design to pull air through restrictive front panels or radiators. Addressable RGB LEDs on the frame and side edges sync with standard 5 V three-pin headers. It suits builders who want coordinated lighting without software lock-in.

PWM speed control with 4-pin fan connector

The fan connects via a standard 4-pin PWM header for automatic speed curves between 800 and 1800 rpm. A separate 3-pin 5 V ARGB plug powers the lighting. No extra controllers or adapters are required if the motherboard provides both headers.

47.2 CFM airflow with 1.6 mmH2O static pressure

At full speed the fan delivers 47.2 CFM and 1.6 mmH2O pressure, enough for mesh-front cases or single-radiator liquid cooling. Noise stays at 30 dB(A) maximum. It is not suited for dense radiator stacks or high-restriction heatsinks that demand higher static pressure.

Questions about this item

How do I confirm the FR-505B is spinning at the correct 800-1800rpm after installation?

Check the fan speed in your BIOS or monitoring software; it should read between 800 and 1800rpm with a tolerance of ±10%.

What connectors come on the FR-505B and what separate cables might I need?

The fan includes a 4-pin PWM power connector and a 3-pin 5V ARGB connector; ensure your motherboard has matching 4-pin and 5V 3-pin headers or buy adapters.

Which airflow and noise figures help me decide if this 120mm reversed fan suits my build?

It delivers 20.98-47.2CFM at 13.3-30dB(A) with static pressure of 0.32-1.6mmH₂O, so compare those ranges to your case's airflow needs.
