Alphacool ES 80 mm PWM Case Fan, 80 x 80 x 25 mm, Black

The Alphacool ES is an 80 mm fan engineered for continuous operation in environments such as servers, workstations, and on liquid cooling radiators. It utilizes a dual ball-bearing motor, a component choice intended to provide consistent operational stability and a long service life under sustained workloads. The fan connects via a standard 4-pin PWM header, which allows system motherboards or dedicated fan controllers to dynamically adjust its rotational speed according to thermal demands.

This model is designed to produce high static pressure, rated at a maximum of 14.29 mmH2O, making it effective for moving air through dense heatsink fins and restrictive dust filters. Its wide operational range of 1,000 to 6,000 RPM allows users to balance cooling performance with acoustic output. The fan also integrates electronic protection circuits and a soft-start function to support reliable startup and operation in performance-critical systems, all within a compact black housing.

• Generates a maximum airflow of 77 CFM
• Features a standard 80 x 80 x 25 mm frame
• Reports rotational speed to the system via an integrated tachometer
• Produces a noise level of 50 dB at maximum speed
• Equipped with a 0.3-meter power and data cable
