120 mm.

• Upgrades the NH-U12S redux to a push/pull dual-fan configuration for improved performance or lower noise levels when running both fans at lower speed
• Can reduce temperatures by 1-3°C, especially on higher heat-loads such as during turbo use, on overclocked systems or higher TDP processors
• Second high-quality NF-P12 redux-1700 PWM fan supports automatic speed control via the motherboard, can provide massive airflow at load and run whisper-quiet at idle
• Low-Noise Adaptors allow the maximum fan speed to be reduced from 1700 to 1300rpm for near-silent operation
• Includes 1x NF-P12 redux-1700 PWM fan, 4 anti-vibration pads, 1 pair of fan mounting clips, 1x 4-pin PWM y-cable and 2x Low-Noise Adaptors
