Purpose & Audience

The Corn Electronics Aurora 120 Angel Eye is a 120mm case fan built for PC builders who want blue LED illumination and a hydro bearing. It suits standard case mounting points and draws power from either a motherboard 3-pin header or a Molex LP4 connector from the power supply. Buyers who need PWM speed control or addressable RGB synchronisation should look elsewhere.

Thermals, Noise & Power

The fan spins at 1500 RPM with a ±10% tolerance and pushes 38 CFM of airflow at a static pressure of 1.3 mmH2O. Acoustic output is rated at 23.5 dBA, which is quiet enough for typical desktop use. Power is supplied at 12 VDC through the chosen connector; the supplier warns that connecting both the 3-pin and LP4 plugs simultaneously may cause a short circuit.

Build & Connectors

The frame measures 120 x 120 x 25 mm and weighs 150 g (0.33 lb). A hydro bearing provides a rated 20,000-hour MTTF. Translucent blades and a halo ring create the blue lighting effect. Four mounting screws and anti-vibration pads are included to reduce transmitted vibration. Only one power connection type should be used at any time.

Questions about this item

How do I install the Aurora 120 Angel Eye Blue fan and which power connector should I use?

Mount the 120 mm fan with the four included screws and connect either the 3-pin header to the motherboard or the LP4 connector to the PSU — never use both at the same time or you risk a short circuit.

What maintenance or replacement will the hydro bearing need after the rated 20000 hours?

The hydro bearing is sealed for its 20000-hour MTTF; once noise or vibration rises past the specified 23.5 dBA the whole fan should be replaced because the bearing is not user-serviceable.

At 1500 RPM what limit appears first during sustained operation — airflow, noise or bearing life?

Bearing life is the limiting factor; the hydro bearing is rated for 20000 hours at 1500 RPM, while airflow stays at 38 CFM and noise at 23.5 dBA throughout that period.
