ARCTIC Freezer A11 provides 150 Watts of peak cooling power and is an ideal replacement for stock AMD CPU cooler with features such as 3 Direct-Touch double-sided copper heat pipes precisely manufactured leaving no gap at the critical contact point to promote quick and efficient heat dissipation. Specially designed fan blades and aerodynamically-shaped fan guard that promote smoother air flow and innovative fan mount with rubber vibration-absorbers further reduce the noise while improving the cooling efficiency. ARCTIC Freezer A11 keeps your processor much cooler than the inefficient and noisy stock cooler, generating less than 23 dBA only even at full load! Newly designed transport-proof mounting mechanism secures the ARCTIC Freezer A11 and the processor tightly minimizing potential shifting during transportation. The long-lasting 92mm fluid dynamic PWM fan creates constant air flow quietly and efficiently. Non-capacitive and non-electricity-conductive MX-4 thermal compound is included for safe and easy installation. ARCTIC Freezer A11 supports AMD sockets: FM2, FM1, AM3+, AM3, AM2+ and AM2. ARCTIC Freezer A11 comes with a 6-year limited warranty. Contact arctic.us@arctic.ac for service.
