Two-pack 120 mm RGB case fans

The Corn Electronics Corona 2-pack supplies a pair of 120 mm hydraulic-bearing fans with 4-pin PWM control and addressable RGB lighting. Each unit runs at 1000-1800 RPM and moves up to 54.51 CFM while staying at 31.4 dBA maximum noise. The fans are designed for standard case mounting and synchronise with Gigabyte, MSI and ASRock motherboard RGB utilities.

Sustained-load behaviour

Hydraulic bearings maintain consistent speed and noise levels during continuous operation, with a rated life of 30,000 hours. The nine-blade diversion design keeps airflow steady across the 1000-1800 RPM range without sudden acoustic spikes. Dual-sided rubber anti-vibration pads absorb motor vibration so chassis resonance does not increase over long sessions.

Compatibility checklist

Verify your motherboard provides a 4-pin PWM header for each fan and supports 5 V addressable RGB control for the lighting. Confirm 120 mm mounting points with 25 mm thickness clearance in the intended case locations. Ensure the power supply can deliver 0.22-0.45 A per fan at 8-13.2 V without exceeding header current limits.

Questions about this item

How loud is the Corona fan at full 1800 RPM during all-day use?

The fan reaches a maximum of 31.4 dBA at 1800 RPM, with a 9-blade diversion design and eight rubber shock absorbers to keep vibration low.

Which motherboard header and software are needed to control the RGB lighting?

A 4-pin PWM header and a 5 V addressable RGB header let the motherboard manage speed and sync colours through Gigabyte, MSI or ASRock utilities.

Will the 120 mm frame and 25 mm thickness fit in the same mounts as my older 120 mm fans?

Yes, the 120×120×25 mm dimensions match the standard 120 mm mounting pattern used by older fans.
