Scythe SCNJ-5100 Ninja 5 Rev. B Processor Air SCNJ-5100

The Ninja 5 Rev. B CPU cooler pays special attention to whisper-quiet operation thanks to the Kaze Flex 120 PWM fans running in dual mode and the generously dimensioned heat sink. The Kaze Flex 120 PWM fans 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). Despite its size, the heatsink has been 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 revised, fourth version of the Hyper Precision Mounting System (H.P.M.S.) is used in Revision B of the Ninja 5, which, in addition to the usual simple assembly, now also offers full compatibility with Intel’s LGA1700 and AMD’s AM5 sockets.

High Memory Compatibility
The Ninja 5 Rev. B CPU Cooler features a special fin design to improve memory compatibility without compromising the cooling performance. The lower fins are reduced in size to allow installation of RAM modules with heatsinks up to 55 mm in height. These fins are present on both sides of the cooler, thus offering memory clearance even for LGA 2066 mainboards with eight memory slots.

Dual Fan Design with Push/Pull Setup
The Ninja 5 Rev. B CPU Cooler features two Kaze Flex 120 PWM fans with a max. speed of only 800 RPM. This Dual Fan Design improves the cooling performance without sacrificing low noise levels. The corners of the fans are equipped with rubber shock absorbers to prevent transfer of any vibration. In addition, the shape of the headsink helps directing the airflow from one fan to the other, thus creating a better heat transfer and dissipation by using the Push / Pull principle.

H.P.M.S. IV (Hyper Precision Mounting System IV)
The Ninja 5 Rev. B uses the updated H.P.M.S IV mounting system which offers full LGA 1700 and AM5 compatibility. A pre-assembled mounting bar with spring-loaded screws ensures balanced pressure distribution. During the installation process, the universal backplate is securely fixed to the mainboard by rubberized spacers, making the process considerably easier
