Fan Alphacool 24845 12 cm 4000 RPM Black

Alphacool Core 120mm is a PWM-controlled 120 mm fan designed for high-performance cooling in computer systems. It operates at 12 V and reaches up to 4000 RPM, offering a maximum airflow of 119.8 CFM and a static pressure of 12.67 mm/H2O. The fan uses a double ball bearing for smooth operation and extended service life and comes in black without ARGB lighting.

Advantages

The Alphacool Core 120mm combines a wide PWM control range (0–4000 RPM) with high static pressure and strong airflow, making it suitable for both radiators and case ventilation. Its dual ball bearing ensures quiet, reliable operation and increased durability. A 40 cm cable with a 4-pin PWM connector allows direct connection to a motherboard or controller without extra adapters.

Suitable for

• Mounting on water-cooling radiators
• Case ventilation in desktop PCs
• Use on CPU coolers that accept 120 mm fans

How to use

Connect the fan to a motherboard or PWM-capable fan controller using the included 4-pin connector. Configure fan curves in the BIOS or through software to take advantage of the 0–4000 RPM control range. Install the fan on a radiator or inside the case using standard 120 mm mounting holes and appropriate screws. Ensure airflow direction matches your intended cooling setup.

Recommendations

For radiator mounting, use fan shrouds or push/pull configurations if space and radiator thickness allow to maximise heat dissipation. When installed as a case fan, position the Alphacool Core 120mm to create a balanced intake and exhaust flow to maintain stable internal temperatures.
