4. ARCTIC Freezer 12 - Semi Passive Tower CPU Cooler for Intel and AMD

• Semi passive cooling: the 92 mm fan only starts up at a pwm signal with 40 % pulse width. this saves energy, extends the service life and makes the cooler at low load completely silent
• Innovative ventilation: fluidic analysis and long testing hours allowed us to push the fan efficiency boundary further. this is leading to greater airflow and cooling at lower noise level
• Optimal compatibility: fast and easy to install on amd am4 and intel 115x, 2066, 2011(-3)
• Easy installation & safe transportation: thanks to different mounting models for various sockets and a backplate, the freezer 12 is not only fool-proof to install, but also absolutely transport safe
• Decisively improved: 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
