The 5th generation of the Ninja CPU Cooler series offers some interesting new features. The Ninja 5 includes two Kaze Flex 120 PWM fans which are significantly more silent solution without compromising the high performance that users expect from the Ninja Series. This goal has been achieved by mounting the two fans using the Push/Push principle and setting the fan rotation limit to only 800 rpm. The award-winning Kaze Flex fans use Sealed Precision Fluid Dynamic Bearings for a long lifespan of 120,000 hours (MTTF). The heatsink is designed for high compatibility, supporting even LGA 2066 motherboards with eight RAM slots. Six nickel-plated 6-millimeter copper heatpipes, a nickel-plated copper base-plate and the black anodized top-plate underline the high-quality workmanship. In addition, the third version of the Hyper Precision Mounting System (H.P.M.S.) is used, which significantly simplifies assembly and offers compatibility with a variety of sockets of the processor manufacturers AMD™ and Intel™.
