Ninja 5 Rev.B


An upgrade from its predecessor the Ninja 5 Rev.B focus significantly on silent operation without compromising the high performance that users expect from the Ninja series. This goal is achieved by mounting two Kaze Flex 120 PWM fans using the Push-Pull principle and setting the fan rotation limit to only 800 rpm. The award-winning Kaze Flex fans use Sealed Precision Fluid Dynamic Bearings (FDB) for a long lifespan of 120,000 hours (MTTF). Massive heatsink and 6 sintered nickel-plated 6-millimeter copper heatpipes, a nickel-plated base-plate and black anodized top-plate underline the high-quality workmanship and  provides top-tier cooling performance. Cut-out fin design offers great compatibility for tall memory. The new H.P.M.S. IV mounting system offers secure and easy-to-install experience for Intel LGA1700 and AMD AM5 sockets.


Top-Tier Cooling Silent Operation

Massive heatsink (53% more area than Mugen 5) constructed with 6 sintered heatpipes and copper base plate to maximize heat dissipation thereby providing a top-tier cooling performance. It is potentially a fanless solution as a complete silent PC cooler.

Tall Memory Compatibility

Cut-out fin design features improve memory compatibility without compromising the cooling performance. It allows installation of tall memory heatsink up to 55 mm in height, even for LGA1700 / LGA2011(V3) / LGA2066 motherboards where RMA are on both side of socket. NOTE: Fan would be lift up with tall memory heatsink.

Dual Fan Design with Push/Pull Setup

Then Ninja 5 Rev.B cooler features two Kaze Flex 120 PWM silent fans at maximum speed of only 800 RPM. The corners of the fans are equipped with anti-vibration rubber shock absorbers effectively eliminating possible vibrations and allow silent operation. The shape of the heatsink helps directing the airflow from one fan to the other, thus creating a better heat transfer and dissipation by using the Push/Pull principle.


Scythe easy-to-install H.P.M.S. IV mounting system presents more optimal contact pressure to the latest CPUs on the market and provides full Intel LGA 1700  and AMD AM5 support.
