Decisively enhanced The successor of the Freezer 11 series convinces all along the line with regards to noise level, cooling capacity, mounting versatility & transport-proofness. As semi passive cooler, the Freezer 12 also works extremely efficiently as the fan only starts up at a PWM signal with 40 % pulse width. The contact surface of the Freezer 12 direct-touch heatpipes does not cover the full protection cap of the CPU, but, more importantly, covers the whole processor DIE of the various compatible CPU. This leads to ideal cooling performance. Semi Passive Cooling With semi passive operation the Freezer 12 provides again a special feature. A sophisticated fan controller that was developed by German engineers allows passive cooling of the CPU during simple applications such as surfing & creating documents. The 92 mm fan only starts up at a PWM signal with 40 % pulse width. This saves energy, extends the service life & makes the cooler at low load completely silent. Innovative Ventilation Fluidic analysis & long testing hours allowed us to push the fan efficiency boundary further. This is leading to greater airflow & cooling at lower noise level, which not only crushes the stock cooler performance but also leaves our Freezer 7 Pro far behind. Optimal Compatibility Fast & easy to install & extremely reliable, the mounting system is compatible with Intel & AMD sockets. Easy Installation & Safe Transportation Thanks to different mounting models for various sockets & a backplate, the Freezer 12 is not only fool-proof to install, but also absolutely transport safe. Versatile Installation Extremely versatile to fulfil your preference on the airflow pattern within the PC case, you can mount the Freezer 12 in any way you want to get the exact airflow you need.
