Zalman CNPS9500A LED Copper CPU Fan For Intel Socket 1155/1156/1150/1366/775 & AMD Socket 754/940/939/AM2/AM2+/AM3 The Zalman CNPS9500 LED CPU Cooler is 100% copper heatsink with aerodynamically optimized tunnel design for maximum cooling efficiency, and innovative and patented, curved heatpipe design for a heat transfer capacity of up to six heatpipes with the use of just three. With optimized heatsink layout for maximum cooling efficiency with minimal materials and 0.2 mm ultra-slim fins for minimized weight and reduced airflow resistance, it features ultra quiet CNPS 92mm opaque fan with blue LEDs, aerodynamically optimized heatsink for smoother airflow and minimal noise, and is compatible with all Intel Dual Core Pentium (Socket 775), Pentium 4 (Socket 775/478), and AMD Dual Core AMD Athlon 64 X2 (Socket 939), Sempron/AMD64 CPUs (Socket 754/939/940).

Adjustable fan speed controller (Fan Mate 2) enables control of noise and fan speed.
