The FAN1156PWM CPU Cooler with PWM Cooling Fan for Socket LGA1156/1155 systems provides reliable & efficient cooling for compatible Intel Core i 3/i 5/i 7 CPUs. With Pulse Width Modulation (PWM) technology, the fan speed can be dynamically controlled by the motherboard, so the fan runs at a speed that suits the operating conditions
- lowering power consumption & fan noise when the system is idle, & delivering maximum cooling under full load conditions.
