The K2 is not too dissimilar to the other dual tower coolers which dominate the air cooling market. It features a pair of aluminium fin arrays which are optimized to work effectively with lower speed fans by utilizing performance-enhancing features. What does set the K2 apart from its counterparts is its set of 8 6mm heatpipes. Yes, you heard me correctly, 8! Each heatpipe transfers heat away from the copper base to the aluminium fin array which makes for some effective heat transfer potential when 8 are combined. A centre 140mm fan is accompanied by a 120mm fan on the front side of the K2. Operating at a maximum of 1100 and 1500 RPM, respectively, and making use of Alpenföhn’s wing-boost blade design airflow should be very accommodating. Controlled by a 4-pin PWM connector which can reduce the fan speed to less than 30%, the fans look as if they offer the perfect balance between noise output and performance.
