Alphacool Core 120mm PWM Fan

The Alphacool Core 120mm PWM fan delivers adjustable cooling performance for system builders. Its hydraulic bearing and 4-pin PWM connector provide a wide control range from 600 to 2500 rpm. At maximum speed it moves 72.63 CFM with a static pressure of 2.42 mm/H2O. The 120x120x25mm frame fits standard mounting points in most chassis.

Suited for quiet builds and radiator use

This fan suits builders who want effective airflow without addressable lighting. The hydraulic bearing supports smooth operation and a long service life at lower noise levels. It is less suitable for users who require RGB illumination or fans with specialised frame designs for restricted clearances. Buyers needing higher maximum airflow or different colour accents should consider other options.

Integrates with standard 4-pin headers

The included 40cm cable connects directly to motherboard PWM headers or dedicated fan controllers without adapters. Operating at 12V DC, the fan draws power from the header and frees up internal space thanks to its standard 25mm thickness. Its high static pressure makes it a strong choice for water-cooling radiators or as a general case exhaust or intake.

Questions about this item

What motherboard header do I need to control the 4-pin PWM fan?

A standard 4-pin PWM header on the motherboard or a dedicated fan controller is required; the included cable is 40 cm long.

Will the 120 mm frame fit the mounting holes on my existing radiator or case?

Yes, the fan measures 120 x 120 x 25 mm, matching the standard 120 mm mounting pattern used on most radiators and cases.

How can I verify the fan is running within its 600–2500 rpm range after installation?

Monitor the RPM reading in your BIOS or fan-control software; it should report speeds between 600 and 2500 rpm depending on the PWM duty cycle.
