Alphacool Core 140mm PWM Fan

The Alphacool Core 140mm is a 140x140x25mm case fan built for quiet, efficient airflow in desktop computers. It connects via a standard 4-pin PWM header and suits builders who want reliable cooling without RGB lighting.

Sustained-load behaviour

Hydraulic bearings keep the axis running smoothly during continuous operation, supporting a long service life and low noise. The 40cm cable reaches motherboard headers or fan controllers directly. Speed is adjustable from 600 to 2000 rpm, delivering 103.03 CFM airflow and 2.81 mm/H2O static pressure at the top end.

Deciding specification

The 2000 rpm maximum speed with 2.81 mm/H2O static pressure determines suitability for radiator or high-restriction case mounting. Buyers needing higher static pressure or integrated lighting should look elsewhere.

Questions about this item

How loud and how much power does the Core 140mm draw when running at 2000 rpm all day?

The fan spins from 600 to 2000 rpm via PWM and delivers 103.03 CFM with 2.81 mm/H2O static pressure at full speed using a hydraulic bearing for quiet operation.

What must my motherboard or controller provide to run this 4-pin PWM fan?

A standard 4-pin PWM header supplies the DC voltage and PWM signal the fan requires; the included cable is 40 cm long.

Will this 140 x 140 x 25 mm fan fit the mounting holes on my older 140 mm radiator or case?

Yes, the 140 mm square frame with 25 mm thickness matches the standard 140 mm mounting pattern used on radiators and cases.
