Ventoinha Alphacool 24853 14 cm preta 2000 RPM hidráulica

The Alphacool Core 140mm (model 24853) is a 140 mm computer fan designed for efficient and quiet cooling. It combines a hydraulic bearing for low-noise operation and long service life with a PWM control range up to 2000 RPM, making it suitable for use on radiators, CPU coolers and as a case fan where good airflow and static pressure are required.

Advantages

The hydraulic bearing ensures smooth, quiet operation and extended lifespan. PWM control over a 4-pin connector allows precise speed adjustment from 0 to 2000 RPM. At maximum speed the fan achieves strong airflow (103.03 CFM) combined with high static pressure (2.81 mmH2O), making it effective on radiators as well as for general case ventilation. The 40 cm cable enables direct connection to the motherboard or a dedicated controller without additional extensions.

Suitable for

• Mounting on water-cooling radiators
• Installation on CPU coolers
• Case ventilation for desktop PCs
• Systems requiring a non-RGB, high-pressure cooling fan

How to use

Connect the fan to a 4-pin PWM header on the motherboard or to a compatible fan controller using the included 40 cm cable. Configure PWM fan control in the system BIOS or via software to set desired RPM range (0–2000 RPM). Mount the fan on a radiator, CPU cooler or in the case using standard 140 mm fan screws, ensuring correct airflow direction for your cooling setup.

Recommendations

For radiator mounting, prioritize orientation that directs airflow through the radiator fins and set PWM curves to balance noise and cooling performance. Regularly check and clean the fan to maintain optimal airflow and prolong bearing life.
