The heatpipes are split in pairs inside the heatsink distributing the airflow more evenly over the plates:

The heatpipes are at 1.2 mm distance from one another in the base of the cooler. The gaps between them are filled with aluminum inserts. The base is more or less even and the finish quality is pretty typical for a cooler with Heatpipe Direct Contact technology.

Alpenfoehn Brocken is equipped with one nine-blade fan that measures 120x120x25 mm:

This fan is very beautiful: its semi-transparent blades and glossy frame make an unforgettable impression:

The rotor sticker reads “DF1202512CL-005”; however, no search engines could locate the original maker of this fan model.

The fan rotation speed is PWM controlled in the interval from 850 to 1500 RPM. It creates maximum airflow of 60.04 CFM and generated 21.4 dBA of noise (this must be the minimal noise level, according to the manufacturer). The fan uses a fluid dynamic bearing that should last 30,000 hours or over 3.4 years of non-stop operation guaranteed.

The fan is equipped with four purple LEDs and sits on the heatsink over four silicone shock-absorbing mounts:

The cooler accessories include another four mounts for the second fan.
