The Ninja 5 CPU cooler brings several innovations and places a special emphasis on whisper-quiet operation thanks to the two included Kaze Flex 120-PWM fans. The fans are mounted in a push/pull configuration and provide good cooling performance despite a low maximum speed of 800 RPM. The proven Kaze Flex series utilizes sealed fluid bearings (Sealed Precision FDB), ensuring a long lifespan of 120,000 hours (MTTF) and exceptional smoothness. The design of the heatsink is optimized for high compatibility, supporting even LGA 2066 motherboards with eight RAM slots. Six nickel-plated 6-millimeter copper heat pipes, a nickel-plated copper base plate, and the black anodized top plate highlight the high-quality craftsmanship. Additionally, the third version of the Hyper Precision Mounting System (H.P.M.S.) is employed, significantly simplifying installation and offering compatibility with a wide range of sockets from processor manufacturers AMD and Intel.
